Historical Context

 * Note: The characters within the story rarely describe historical events within helpful context, so the unit BA, “Before Arrival”, and AA, “After Arrival”, will be used to place moments in time with the best available knowledge. Both are in reference to Natsuki Subaru’s arrival in the world. In this case, only BA will be used. Also, note that the units are not official.

Great Calamity (大災厄 Daisaiyaku): The Great Calamity is a critical event in the Re: Zero world that occurs approximately 400 BA, or 400 years before Natsuki Subaru is summoned to the new world, in which the Witch of Envy first appears. Her rampage results in her almost destroying the world and is subsequently fought and sealed by the Sage, the first Sword Saint, and the Dragon. See Great Calamity for a more detailed explanation of the event.

Demi-Human War (亜人戦争 Ahito Sensō): The Demi-Human War is a term used to describe the largest civil conflict between Demi-Humans and Humans within the Dragon Kingdom of Lugunica, taking place from 50 to 41 BA. The conflict resulted in the human victory, in no small part due to the combined efforts of the Zellgef Squadron and the Sword Saint of the era. See Demi-Human War for a more detailed explanation of the event.

Silver Flower Dance of Picoutatte (銀華乱舞): Two notable duels taking place in the city of Picoutatte between the Sword Demon Wilhelm van Astrea and Vollachia's strongest warrior, Eight-Arms Kurgan, roughly four decades before the start of the main series. During their first duel, both of the men were fighting on behalf of their respective countries–Wilhelm fought for the Dragon Kingdom of Lugunica, and Kurgan fought for the Sacred Vollachia Empire. The duel ended in a draw, as Stride Vollachia intervened in the fight after Kurgan shattered Wilhelm's right half of his body, and Wilhelm cut off one of Kurgan's arm;Stride did not want to lose his bodyguard just yet. Their second duel took place roughly 3–4 months after their initial duel, in the very same city. This time, however, the duel ended with Wilhelm destroying one of Kurgan's four Demon Cleavers and inflicted mortal wounds all over his chest, leaving him to bleed out–which he would have, if the Divine Dragon wouldn't heal him, after ascending upon the city.

Subjugation of the Blight Dragon (邪龍討滅戦): An event, taking place roughly a year after the end of the Demi-Human War and 3–4 months after the first Silver Flower Dance of Picoutatte. It is widely regarded as one of the worst days in the Kingdom's history. On one faitful day, Stride Vollachia, along with his subordinates–two Shinobi, Twin Shura, the sole survivor of the Evil Eye Tribe, Ashen Bride and the Vollachia's strongest warrior, Eight Arms–and the kidnapped Sword Saint, made his appearance in one of the Five Great Cities, Picoutatte. They kidnapped and killed twenty civilians who bore a Divine Protection and summoned the Black Dragon Valgren. During the nighmarish battle, hundreds of civilians and soldiers from the Subjugation Squad lost their lives and the majority of the city was utterly destroyed. At the end, the Kingdom managed to break the Magical Circles preventing any distubrance with the outside world. In accordance to his covenant with the Dragon Kingdom of Lugunica, the Diving Dragon descended over Picoutatte, purifying Valgren into nothing more than a pile of ash, healing the numerous wounded and exstiquishing the fires burning throughout the city. Despite the gravity of the attack, the casualities were less than a third of what they anticipated. See Subjugation of the Blight Dragon for a more detailed description of the event.

The Day of Red Earth and Sky (天地赤日): Seven years before the main story, Puck unfroze Emilia from the ice she was imprisoned in. It was only a half year later in 6 BA when Melakuera, the Great Spirit of Fire, came in contact with the former two, and acted in accordance with his beliefs. Stating that Emilia was a threat to the equilibrium of the world, Melakuera decided to exterminate her due to being a "Witch". However, Puck couldn't allow the former to happen, thus he decided to fight him. Ultimately, Elior Forest became the battleground of Melakuera and Puck's clash, with the latter being the victor of that battle. That day became infamously known across Lugunica as the "Day of Red Earth and Sky". See Re:Zero Prequel: Bonds of Ice for a more detailed description of the event.

The Royal Abduction Incident (王族誘拐事件): The Royal Abduction Incident is a term that describes a significant event taking place 14 years before the events of the Arc 1. A supposed group of kidnappers were claimed to have snuck into the Royal Castle and abducted Ford Lugunica's daughter. A large scale search led by the Captain of the Royal Guard Wilhelm van Astrea had spawned, however, the child was never retrieved. According to rumours, the Vice Captain of the Royal Guard Heinkel Astrea was involved with the incident, apparently even allowing the intruders to escape with the little girl. While not outright confirmed, it's heavily implied by knowledgeable individuals such as Reinhard and Miklotov that Felt might very well be the missing child, as she is as old as the kidnapped girl would've been, shares the trademark appearance of the members of the Royal Family, and has a name she doesn't know about.

The Great Conquest (大征伐): The Great Conquest is a term used for the first Hakugei hunt led by the previous Sword Saint Theresia van Astrea, in 14 BA. Though it was originally supposed to be lead by the Royal Guard's Vice Captain Heinkel Astrea, the leadership was granted to his mother Theresia, after Heinkel had outright refused to lead the subjugation and recommended his mother to do the job instead of him, despite Theresia putting away her sword for good and vowing not to use it ever again. As expected, the subjugation ended disastrously, as the vast majority of the Royal Knights had been slain, including Theresia, who had lost her Divine Protection of the Sword Saint mid-battle. What most do not know, however, is the involvement of a mysterious figure who sided with the Hakugei and attacked the Royal Knights and the Sword Saint–the Witch of Vainglory. Immediately following the loss of her Divine Protection of the Sword Saint, Theresia encountered the lone girl amongst the mist. Sensing danger, she sprung into battle, but subsequently died off-screen. It's heavily implied Pandora is somehow connected to Theresia's demise.

The Silver Flower Dance of the Sword Saint and the Lightning (剣聖と雷光の銀華乱舞): A duel between Lugunica's Sword Saint Reinhard van Astrea and Vollachia's 1st ranking Divine General Cecilus Segmunt. Roughly half a year before the start of the Royal Selection, Vollachia's strongest individual Cecilus Segmunt uninvitely showed up in the Capital of the Dragon Kingdom of Lugunica, in search of the Sword Saint, requesting a rematch. The duo were allowed to have a proxy duel with both of them representing their respective countries. In front of the Training Ground Arena chalk-full of knights, Reinhard drew the Dragon Sword Reid for the 3rd time in his life. Both survived the duel and the match was declared a draw.

The Hunt for the Hakugei: Roughly a week after the Royal Selection Ceremony, Emilia Camp successfully formed a temporary alliance with Crusch Camp, by offering Crusch valuable information–the Demon Beast's exact time of appearance–in exchange for their help in defeating the Hakugei. With the help of Russell Fellow and Anastasia Hoshin, a subjugation group consisting of Karsten's private army, old Zellgef Squadron veterans, the Sword Demon, Iron Fang members, Rem and Subaru, departed towards Liphaus Highway. There, the army engaged with the Hakugei at 3:30pm (which doesn't corelate to the new world's time, as the clock stopped working properly once Subaru was summoned to the new world). The battle ended in triumph, after Wilhelm van Astrea had delivered the finishing blow, finally avenging his deceased wife which had been taken from him from that same beast, 14 years prior.

The Subjugation of Sloth: Roughly a week following the Royal Selection Ceremony and mere hours after the successful Hunt for the Hakugei, a group of fighters consisting of the same people that were present during the Hunt for the Hakugei plus new reinforcements consisting of Julius Juukulius and unnamed members of the Iron Fang departed towards the Mathers Domain, where the Witch Cult led by the Sin Archbishop of Sloth Petelgeuse Romanée-Conti was said to slaughter Arlam Village and Roswaal Manor. After having successfuly evacuated the villagers and Emilia, the team of subjugators managed to engage with the Witch Cultists and their leader, promptly defeating them. The fight wasn't over yet, though; following Sloth's defeat, the subjugation force learned of a cart that was rigged with a large quantity of Fire magic stones set to explode and wipe out the entire convoy in a blink of an eye. Subaru – with the help of Otto Suwen – managed to catch up with the convoy and dispose of the Fire magic stones in the headless corpse of the Hakugei, but not before battling the bloodlustful Evil Spirit of the Sin Archbishop Petelgeuse who refused to die, setting him on fire and crushing him underneath the cart's wheels. The result of the Sloth Subjugation Battle was a total victory over the Witch Cult, with no casualities taken on the Subjugation Squad's side.

Races and Clans/Tribes
Elf (エルフ): Elves are a race of Demi-Humans known for their longevity and beauty. Because of the Witch of Envy, Elves were also the target of prejudice from others. Currently, the only known elven community to appear in the story are frozen in the Great Elior Forest.

Oni Clan (鬼族): Among the numerous humanoid races that existed in the world, the Oni Clan were considered the mightiest. Their powerful bodies and the potency of the mana quality they employed, both granted the Oni peerless combat strength. However, as the members of the race had a elitist mindset, in order to preserve their purity and pride, enacted strict taboos and lived in villages in the mountains, away from others. Accordingly, the number of Oni was always low. The few Oni settlements tended to be small rural villages located in mountain ranges that adhered to a strong Social Darwinist and isolationist way of life. The only visible physical difference between a Oni and Human were a pair of long curved-horns that sprouted from the forehead of an Oni, when their lives were in danger. The horns would absorb mana from the atmosphere, greatly increasing an Oni's physical and magical capabilities. Twin demons were usually only born with one smaller horn each, thus making them weaker than their two-horned kin. There do exist those with only one or even no horns the latter which are known as Hornless, and were considered the dregs of their society because of it. Moreover, Oni born that way were to be killed by tradition to protect the Oni pride as a powerful and nearly perfect species. The village Ram and Rem lived in 10 years prior to the main story was the last Oni village, effectively making them some of the few Oni left alive in the entire world. Roswaal remarked that the Oni's demise was because of natural selection, as they refused to accept new ideas and not because of discrimination or prejudice.

Giant (巨人): Giants are a Demi-Human race of massive people with tremendous strength and a lifespan of around 150 years. They fought in various places during wartime and because of that their numbers dwindled. The only known Giant in the Royal Capital of Lugunica is Rom. It is mentioned that Sekhmet, a giant herself, killed most other Giants.

Evil Eye Tribe (魔眼族): The Evil Eye Tribe are a type of Demi-Humans that were wiped out by the Empire. There were originally not that many of them and they possessed the ability to see invisible things and interfere with the minds of others with their eyes. Rumours say that there are still living members existing. In fact, throughout the story, there have been quite a few Evil Eye members that have made their appearance, namely in the side stories.

Mole Humans (土鼠人): The Mole Humans are a type of demi-human that used to formerly reside in the Vollachia Empire. However, according to history, they betrayed a woman named Iris, causing the Empire to hunt them down. More than a hundred years ago, a group of Mole Humans dug the Everlasting Darkness (常闇) that connects between the Shamrock Valley in Lugunica and a place near the Vollachian town of Mozotto, where they still reside in the present.

Puppy Humans (子犬人): The puppy humans are a race of small demi-humans that have dog-like features.

Dog Humans (犬人): The dog humans are a race of demi-humans that have dog-like features.

Wolf Humans (狼人): The wolf humans are a type of demi-human that used to formerly reside in the Vollachia Empire. However, according to history, they betrayed a woman named Iris, causing the Empire to hunt them down to the brink of extinction. With the exception of Halibel, the only known wolf humans to publicly profess his heritage, the majority of wolf humans hide their heritage by pretending to be dog humans.
 * Werewolf (人狼): Werewolf is a term for demi-humans who are half wolf human. Like other beast humans, werewolves possess the ability to beastify.

Wolfin Tribe (ウルフェン族): The Wolfin Tribe are a rare type of demi-human who are at the brink of extinction. There is an anecdote about the Wolfins being raised to refer to themselves as Kobolds. Due to how they hide their true heritage, it is possible that they may be related to wolf humans.

Kitten Humans (子猫人): The kitten humans are a race of small demi-humans that have cat-like features.

Hyena Humans (鬣犬人): The hyena humans are a race of demi-humans that have hyena-like features.

Bat Humans (蝙蝠人): The Bat Humans are a species of demi-human that lives near the town Mozotto of Vollachia. They have night vision and an excellent sense of hearing. They often kidnap humans to drink for blood and choose targets based on whether their blood is good or bad. As long as there's no resistance, they won't do any harm to their targets. What's more, they were extremely attracted to rare blood which can deprive them of their normal sense of judgement. Bat Humans' leader is Jacques-Rosé Blau (ジャッカローゼ・ブラウ, Jakkarōze Burau) who calls himself the Lord of Blood (血主, Chi-nushi). Bat Humans also have a "instinct" that can help them sense the danger in the future. Jacques-Rosé himself has sensed the upcoming Great Disaster in the Vollachia Empire and sought to use the "blood bride" to power himself up to prepare for the disaster.

Dwarf Tribe (小人族): The Dwarf Tribe are a common type of Demi-Human that are shorter than normal humans.

Boar Tribe (イノシシ族): The Boar Tribe were usually an uncommon race of Demi-Human, but due to the Demi-Human War and the Sword Saint nearly wiping out their existence, their kind are now rarely seen. They are about the same size as the Wolfin Tribe. They have a head of a boar with a human physique.

Multi-Arm Clan (多腕族): A once nomadic race who finally settled down in the Vollachia Empire decades ago. They are few in number, and with exception of Kurgan, they typically have 4-5 arms.

Steelfolk (鋼人): The Steelfolk are a special type of race and unlike other races. They're rarely seen on the surface as they mostly travel underground, and they're additional a race that's different in mentality and hard to communicate with compared to humans.

Insect Cage Clan (虫籠族): The Insect Cage Clan is a minority group of various Demi-Humans existing only on the Vollachian soil. The clan consists of different demi-human races who–at a young age–ingested a special type of insect with magical properties, allowing them to eventually adopt their powers. The individual's Od syncs with the insect's Od, allowing them to share their souls, merging them into a single living being. By doing so, the person's external appearance drastically changes into that of a bug, giving them a gruesome appearance most people fear, but most importantly, a means of attacking. They're encased in a bug's shell that can easily deflect powerful attacks, have wings that allow them to skillfully maneuver around the battlespace and long hardened limbs which resemble a sickle. Known throughout the Empire for their deadliness and effectiveness, the Insect Cage Clan has no shortage of unique and special attacks which cause most–if not all–warriors a very tough time. Coupled with their large numbers, they're very effective assassins for dispatching groups of powerful foes threatening the Emperor.

People of Shudrak (シュドラクの民): A clan located deep in the Buddheim Jungle. It's a purely female-born race. The clan's people are known for being descendants of war gods who lived in the jungle for hundreds of years. They reproduce with men from the outside. Members of this clan are dark skinned and have pitch black hair, similar to Subaru's. As expected from a warrior clan, the Shudraks have mastered the art of guerrilla warfare, using the terrain to their favour, dispatching their targets with poisonous arrows, deadly precision and devastating traps. According to Vincent Vollachia, the Clan was once saved from a predicament by a previous Vollachian Emperor.

Cyclops Tribe (単眼族): A giant-like race of demi-humans with one eye in middle of their head. Their eyes can see much further than any other race and they are sensitive enough to not only be able detect smallest movement within an individual, but also concentrations of mana or heat. They also have the capability to perceive emotions.

Weaponkin (刃金人): A race of demi-humans born with parts of their bodies metallized which they reshape into any weapon of their choosing as they grow up.

Glow People (光人): A race of demi-humans with glintstones in their heads. The glintstones are said to absorb the souls of those who they kill.

Dragonkin (竜人): The dragonkin are a rare race that possess the ability to make emotional connections with the three kinds of lesser dragons, though they are mostly extinct in the present. The dragonkin differed from other races related to humans at a basic level, meaning that they were not demi-humans. After driving ten other races to extinction, they were nearly led to extinction as a result of their extreme pride. The race's only known survivor is Madelyn Eschart.

Powers and Abilities
Magic (魔法): Magic is a paranormal power that alters mana passing through a being's gate into a form that has an effect on reality. For a more detailed explanation (including different types of magic and all spells currently used), see Magic.

Authority (権能): Authorities are various abilities the Witches, Sin Archbishops and certain other rare individuals use. For more information, see Authority.

Witch Factors (魔女因子): Witch Factors are special, abstract factors that enable people to use authorities. For more information about the Witch Factors, see Authority.

Divine Protection (加護): Divine Protections are various powers that may be given to someone at birth. For a more detailed explanation as well as a list of every Divine Protection featured thus far in the story, see Divine Protection.

Spirit Arts (精霊術): Spirit magic is a type of craft similar to magic that Spirit Arts users employ.

Spirit User (精霊使い): Spirit users, such as Emilia, are people that are contracted with Spirits, and use them in various situations. There are three different classes of Spirits; Lesser Spirits (微精霊 Biseirei), Quasi Spirits (準精霊 Junseirei), and Spirits (精霊 Seirei). There are also man made Spirits known as Artificial Spirits (人工精霊 Jinkou Seirei) which were created by the witch Echidna. Unlike Magic users, Spirit Users gather mana from outside their body. The only downside to Spirit Users is that the greatest amount of mana they can use at one time, is dictated by their contracted spirit. The greater the spirit's capacity for mana, the bigger the spells its contractor can cast.

Curse (呪い): A subcategory of spiritual and magical arts that originated from the country of Gusteko. The most notable traits about curses are they cannot be defended against once activated and they are the most effective class of magic when it comes to killing. However physical contract between the caster and target is mandatory for curses to work. Furthermore, unlike other normal magic, Curses are only limited to taking lives and have no other application in society beyond that. This caused the practice to become taboo leading it to fall out of favor among mainstream Magicians. Incidentally, there are Demon Beasts such as Wolgarm who are capable of inflicting curse spells through their bites and draining mana of the victim.
 * Curse Doll (呪い人形): Curse Doll is a curse which involves the user carving a curse mark that includes the information of the target they want to kill on someone, and upon activation, the person with the curse mark gains immortality, but as a cost they lose their sense of self and can't do anything else but kill the target and they die when the target is killed. Also, there seems to be a limit on the immortality. However, there's supposedly a way to cast the curse without the person losing their sense of self, which is what happened to Elsa, though repeatedly dying turned her into a curse doll.

Wall Strike (壁当て): A combat skill where, by controlling the mana inside the body, a shockwave is produced that can pass through obstacles.

Soul Transference: It is a lost forbidden magic art that allows a person to move their spirit from one body to another by over-writing the soul of the target body with their own. By doing this over and over to extend their life indefinitely, the user can achieve what Beatrice termed as "subjective immortally". However it has one major restriction in that for it to work, the person whose soul is overwritten must be of blood-relation to the caster. The spell was originally created by Echidna to gain immortality, but she could not complete it before falling at hands of the Witch of Envy. Instead, it was finished by Roswaal who had been using it to survive until the present era.

Magic Circle (魔法陣): A type of geometric magic algorithm used to perform complex spells and rituals that can be drawn on the earth or a living being. These can produce great kinds of effects such as large-scale magic that completely alters the state of a battlefield, imbuing an individual with extreme power, or even temporarily cutting off Divine Protections. However "Magic Circles" drawn on the ground once found can have their spells be disputed and the range of the effects of the magic only extent as far the circle's physical range so hiding them until activate is necessary. Since this is ancient magic very few people know about it and even fewer are capable of using it. Magic Circles were deployed frequently by demi-humans during the civil war.

Spirit Eaters (精霊喰らい): Spirit Eaters are people, who can eat and absorb spirits of all kinds, which in turn allows them to use those spirits' abilities until they digest them. A downside to this ability is high susceptibility to mana poisoning. By being exposed to larger quantities of mana, Spirit Eaters get sick way more easily than normal people. Spirit Eating was originally a secret technique found with members of specific tribes that were situated at the frontier of the Vollachia Empire. Due to its insane potential and strength, however, the tribes were brought to ruin and the technique was lost to time. Currently, only one Spirit Eater remains alive and known to the world–the 2nd ranking Divine General Arakiya.

Soul Marriage (魂婚 Konkon): This technique allows Yorna to share her power with anyone, under certain specific conditions. It is said to be one of the lost secrets of the old world and consists of giving away a part of the user's own Od to one or many individuals, provided that they "love" the user. Talented users are even able to use this technique on inanimate things, such as her Kiseru and the Crimson Lapis Castle which she can manipulate at her own will. The people under its effects are stated to have red flames in their eyes, as well as immense strength and enhanced self-healing.

Dragon Kingdom of Lugunica
Council of Wise Men (賢人会): An advisory board that supports Lugunica's ruler comprised of accomplished and distinguished people. They are currently administrating the country in place of a king until the Royal Selection is over. The amount of members is not known, but two of its known members are Miklotov McMahon and Bordeaux Zellgef.

Six Tongues (六枚舌): A secret intelligence order of the Dragon Kingdom of Lugunica, created by Bordeaux Zellgef and currently led by Russell Fellow. Its top priority is to ensure the stability of the Kingdom. Known members include Orphe and Helaine Gatness.

Council of Ten (十人会 Jūninkai) A council that led Priestella. After the events of Arc 5, the whole council was annihilated except for Kiritaka, leaving him as the last survivor of the Council.

Royal Army (王国軍 Ōkoku-gun): An organization that is the military force of the Kingdom of Lugunica. For more information, see Royal Army.

House Karsten (カルステン家): The most prominent noble family from the Dragon Kingdom of Lugunica. For more information, see House Karsten.

The Brotherhood (同胞団 Douhou-dan): An organization that was led by Marcos Gildark 15 years before Natsuki Subaru was summoned into the world. The organization was created to fight against the class-discrimination that was occurring in the Royal Capital at the time.

The Golden Wing Faction (金翼党, Kinyoku-tou): An organization that was led by Fareed Impusen 15 years before Natsuki Subaru was summoned into the world. The organization was created by nobles who lacked a sense of purpose because they were born as third and fourth sons, and the like, thus failing to inherit major duties in their lineage. The organization acted as a vigilante group to quash crime in the Royal Capital.

The Big Three (三巨頭, San Kyotō): A term used for the three most powerful groups of Flanders' underworld.
 * Black Silver Coin (黒銀貨, Kuro Ginka): One of the factions of the Big Three, led by Doltero Amule.
 * Flower Prison Garden (華獄園, Hana Gokuen): One of the factions of the Big Three, led by Toto. They are known to have a very bad relationship with The Scales. They specialize in prostitution.

Magic Related
Mana (マナ): Mana is a type of colourless supernatural energy that exists in the atmosphere which can be found basically everywhere. When magic is being processed, a person's innate attitude will charge the mana particles to their specific “element”, which briefly manifests as formless spell-form before taking shape of the spell chosen. When a person casts magic, they will experience brief physical and mental fatigue which results in sudden weakness if they are not used to expelling magic or if they overcast beyond their capacity. Mana is also used in martial techniques and special abilities such as beastification, making superhuman feats possible, although beastification is often used by individuals who are not very proficient in using magic directly. Mana itself originates from the Od Laguna, the world's Od.

Gate (ゲート): An invisible portal-like apparatus that exists in every living thing. It allows mana to pass through the body and be stored in the Od. Whether one can use magic or not entirely depends on its condition; be it either fully or partly open. Most people only have partly functioning gates so magic is out of reach to them. In addition, there are some with a defective gate that keeps them from releasing mana at all. Overcasting magic can also lead to damaging the gate, and then the permanent loss of magic if the user continues to do so without treatment. However, that is difficult to obtain and if the gate breaks before that then nothing can be done.

Od (オド): Od is the life energy that dwells inside of a living being from birth which is synonymous with the soul, making it the opposite of mana, which is magical energy that exists in the environment. It varies from person to person in terms of quantity and size which represents the lifespan of an individual. It also acts as a vessel for storing mana that flows through the gate from the environment, so having a large capacity is especially beneficial to those who can use magic. Od can be used in place of mana to cast magic, however unlike mana, using Od is like using your own lifespan, and so it isn't recommended outside of emergencies. In case the user runs out of their Od, they won't die but they also won't be themselves anymore. According to the author, such people soon become crippled. Under special conditions, an individual is able to encase themselves in their own Od which will act as some sort of a separate world that is even free from the influence of Authorities. During the events of Arc 5, Anastasia Hoshin used this technique to avoid the consequences of the Authority of Gluttony in order to not forget her knight Julius Juukulius.

Od Laguna (オド・ラグナ): Od Laguna–often referred to as the "world" in layman terms–is a vast storage of mana located at the origin of the world itself, or in other words, at the world's core. It is where all mana comes from in the world, a eventually goes back to. No one knows where it is located and the Author once state that it's an entity similar to the Sun, as it has no will of it's own. It is said that those who stumble over prohibited arts have had their spirits destroyed by simply looking at it. Some speculate that it is the world's will and gives Divine Protections to people. Its main function is to provide stability to the world and its inhabitants by regulating mana, souls and other aspects of life, while limiting the frequency of natural disasters that occur due to mana oftentimes running short. Mana flows from Od Laguna to every individual's Od, which is connected to it via their gate. How much one receives depends on the size of the gate, e.g. the bigger it is the more mana they get, which also affects their aptitude for magic. When mana is expelled from an "Od" through the individual's gate, it can be used to either create magic or power objects such as "magic stones/lagmites" or meteors. Once spent, the residue mana lingers around, becoming atmospheric mana, which Spirits and Spirit Art Users can harness. Eventually, the atmospheric mana returns back to Od Laguna, restarting the cycle again, for all eternity. While Od Laguna does not necessarily possess a physical form, the Author has claimed that Reinhard would be able to defeat/destroy it, if he was ordered to.
 * Corridor of Memories (記憶の回廊): A vast endless white space within Od Laguna, where souls of the dead go to get filtered of their impurities, or in other words, the memories of its previous life, before they get reused. Those memories in turn are then recorded & preserved by turning them into Books of the Dead, which are stored in the Pleiades Watchtower's library.

Defective Gate: A medical term for individuals whose Gate cannot perform the normal circulation process of either absorbing or expelling mana. If the former occurs that person cannot use magic unless they expend their Od. If its the latter, then they are at risk of "Mana Poisoning".

Mana Poisoning: Mana Poisoning is a state in which an individual continues to absorb an excess amount of mana beyond their Od's capacity, but is incapable of releasing it, which will eventually destroy their Od and kill them. Improperly configured or defective gates are the common casue of this. Individuals in this status who don't receive constant treatment are often very sick.

Magic Release Period (発魔期, Hatsumaki): A phenomenon that occurs to individuals and beings who possess potent magical power, powerful gates and Od that allow them to draw-in and store more mana than they let out. It happens when a magic user doesn't maintain a proper release cycle to let off excess mana from their Od which causes it to overflow from beyond their bodies. It can have drastic effects on the person such as mana poisoning, and it can even affect the environment. The mana will eventually burst out of and damage their gate if it's not forcibly released and released from within them.

Flow Method (流法): A method of handling mana within one's body and utilizing it in order to enhance their own physical strength. Mana-based marital art techniques such as "Palm of the Fist King" can be created and performed with mastery.

Oaths: In the world, there exist concepts known as contracts that can either be magically binding or honour-binding. They are collectively known as oaths, which are broken down into three main categories.
 * Pacts/Contracts: Two parties can form oaths, which are usually made between spirit-sensitive humans or Demi-Humans, and Spirits. By doing this, the formerly mentioned parties form a symbiotic relationship with Spirits, and become what is known as a Spirit Art Users.
 * Covenants: Covenants are oaths formed between entire bloodlines, rather than just specific individuals, such as the one between the Kingdom of Lugunica's late Royal Family and the Divine Dragon, which vows the Dragon to aid the Kingdom when in need. Covenants are usually long-lasting (for several generations).
 * Vows: Oaths that either binding two individuals or a single party. They can be magically backed, or simply honour-based promises or agreements.

Miasma (瘴気): Miasma is invisible contaminated mana that exudes from those who hold the power of witches or are connected to them. The Witches of Sin, the Sin Archbishops of the Witch Cult, Demon Beasts and to a smaller extent low-ranking cult members are prominent examples of this. While the criteria for it aren't known, this miasma can be sensed by certain individuals who are sensitive to it. Miasma is normally harmless when it is in small doses, however in high density, it will start having negative effects on all things; living beings with gates will be driven into madness, food will be polluted and go on to corrupt those who eat it. Demon Beasts are attracted to those who give it off and will deliberately attack them as well as grow stronger in places where it is very prevalent.
 * The Witch's Scent (魔女の香) is a similar type of scent exclusively belonging to Satella, and the Witch's Lingering Scent (魔女の残り香) is a scent that those connected to the Witch of Envy have, such as Natsuki Subaru.

Lagmite: Also known as magic stones or glintstones. They are created when atmospheric mana crystallizes under specific conditions over a period of time. Magic crystals are a large type of magic stone that grow over a significant amount of time and have no impurities, but very few currently exist. With the exception of one, they come in six elements and serve many practical functions in society. Fire lagmite can be used in mechanisms for cooking, heating baths or lamps. Earth types are used for strengthening structures like pots or buildings, or used as fertiliser when buried in the ground. Yin and Yang lagmites are often made use of in powering meteor devices. Any living being that has a "gate" can come in contact and use them. The individual does not need to be able to use magic themselves to make use of them. Crystals in raw form are volatile and need to be handled with care otherwise their will unleashed mana stored within with explosive effects.
 * Glintstone (輝石): A rare colourless type of lagmite crystal that unlike a normal mana crystal is very small. They are only found in a place that has a high density of mana. The crystal has been demonstrated to hold incredible powers such as being able to store souls, spirits and fragments of one's Od. In addition to that, it can be used as a means of containing and controlling magical algorithms that generate spells. It often functions as a kind of key for people to pass into places that are otherwise very difficult or impossible due to powerful barriers.

Surplus Mana Circulation Constitution: Words that Ezzo used to describe the physical constitution/make-up which could absorb mana without using Reinhard's technique.

Magical Books: Magical Books are books which can only be read by individuals who are well versed in magic, and can utilise mana. The books look plain on the outside and have blank pages, however, if the reader concentrates, letters made out of mana appear, allowing the holder of the book to read it. According to Beatrice, Echidna had an infinite amount of Magical Books stored in her library.

Story Specific
Gospel (福音): A black book that lists the holder's future. The information is more detailed if the miscalculation between the holder and the world memory is low.
 * Book of Wisdom (叡智の書 Eichi no sho): The Book of Wisdom is a white book crafted by Echidna that allowed her to draw knowledge from the world's memory. The book didn't just know the present and past, it also knew what would happen in the future, and drew its needed information from there. The mind of an ordinary person attempting to read it would be fried by the sheer amount of knowledge flowing into the reader's mind.
 * Roswaal and Beatrice's Books of Wisdom:Beatrice's Gospel ep.32.png Two imperfect gospel books created by Echidna for Roswaal and Beatrice. They allow the holder to use a limited version of the original Book of Wisdom and only two exist in the entire world. Roswaal's book was destroyed by Ram and Beatrice disposed of hers to form a contract with Subaru.
 * Witch Cult's Gospel (魔女教徒の福音): Defective gospel books that are given to potential Witch Cult members. They show the members a route to a future they desire through vague details. These books can only be read by the holder and appear to be incomprehensible to others.

The Trial (試練 Shiren): Roughly two months after Subaru's arrival to the new world, the Royal Selections kickstarted and with them, Emilia's presence became known throughout the entirety of the Dragon Kingdom of Lugunica. Accordingly, the Witch Cult learned of her existence and the Sin Archbishop of Sloth Petelgeuse Romanée-Conti's Gospel instructed him to perform the Trial on her. Though the details of the trial were never discussed thoroughly in the main story, the Ayamatsu IF story provides us with a more detailed description coming directly from Petelgeuse's mouth – the trial is supposed to determin wether Emilia is a suitable vessle to inherit the soul of the Witch of Envy, which would, according to the Witch Cult, prove effective in resurrecting the Witch of Envy. Due to the combined efforts of Natsuki Subaru, Crusch's faction and Anastasia's faction, however, the Witch Cult was stopped and Sloth was slain by the hands of Julius Juukulius and Subaru Natsuki, rendering the Trial seemingly unsuccessful. It should be mentioned, however, that during one of the failed loops Petelgeuse states to Emilia the following: "Though I must say... Unable to pass even a single trial, not even facing a single Deadly Sin, bearing great expectations only to stumble over the frist stone in her path...". Though no explanation has been given for this line in specific, it does beg the question if the Trial conducted by Petelgeuse in Arc 3 is all there is to it, or if there's more to this Trial than meets the eye.

Dragon's Blood (龍の血 Ryū no Chi): A Dragon's blood is blood taken directly from a Dragon, which acts as a miracle agent. It's said that it's capable of curing any disease and even reversing famine instantly. Only the rulers of the Kingdom of Lugunica have access to it, as it is stored in the Royal Palace's vaults. In order to receive it, however, one must kill a Dragon and collect the blood from its last heartbeat. In Volume 26, it is noted that the Dragon's blood stored away in the Royal Castle doesn't belong to the Divine Dragon Volcanica, but rather, to a different Dragon which was as powerful as Volcanica.

Trials of the Tomb (試練): The trials are three different events that take place at Echidna's Grave at night and clearing them releases the barrier on the Sanctuary. Only halves and people who have been given the right by Echidna may take the trials. If anyone unworthy enters, they suffer ill effects such as feeling bad or getting injured. The effects are stronger the more the person is talented.
 * The First Trial (第一の試練): The beginning phrase is "First off, face your past". The trial taker is shown their past and told to get rid of any regret by either accepting or rejecting their past. The trial is finished if the trial taker either accepts that they change or decides that they won't change.
 * The Second Trial (第二の試練): The beginning phrase is "See the unimaginable present". The trial taker experiences themselves living a different life. The trial is finished if the trial taker chooses reality over their dream.
 * The Third Trial (第三の試練): The beginning phrase is "Face the impending disaster". The trial taker becomes conscious and is shown probable futures they will experience. The trial is finished if the trial taker chooses to keep on going even if they know that a tragic future is waiting for them.

Book of the Dead (死者の書): Special mediums that connect to the Corridor of Memories within Od Laguna where one can access memories of the deceased. They are found in the Taygeta Library of the Pleiades Watchtower.

Four Major Disasters (大いなる四つの災い, Ōinaru Yottsu no Wazawai): The four major disasters, also called the four disasters (四つの災い, Yottsu no Wazawai) are four different incidents in each of the Four Great Nations which are said to lead the world to destruction. These disasters include the Kingdom of Lugunica's Witch or Witches, the Kararagi City-States' Night Weeping, the Holy Kingdom of Gusteko's Collapse, and the Sacred Vollachia Empire's Great Disaster.
 * The Great Disaster (大災, Taisai): The Great Disaster is a disaster foretold to bring ruin that not even the light of the sun can reach to Vollachia. According to Ubilk, the Great Disaster is an inevitability that cannot be prevented, and it must only begin with the death of "Vincent Vollachia". However, Ubilk also says that it is possible to ward its destruction away. Chisha Gold used his transformation ability to impersonate Vincent Vollachia and became the fated individual who died in the Great Disaster, saving the true Emperor in the process. The disaster itself was bore by Sphinx, who revived legions of zombies for her plan to destroy the Empire. See Great Disaster for a more detailed explanation of the event.
 * An incident in Chaosflame where a great shadow expelled from Natsuki Subaru is also temporarily known by this name. However, it is not the true Great Disaster.
 * The Night Weeping (夜泣き, Yonaki): The Night Weeping of the City States is a disaster foretold to bring destruction to Kararagi. The details of this disaster are unknown.
 * The Collapse (崩落, Hōraku): The Collapse of the Holy Kingdom is a disaster foretold to bring destruction to Gusteko. The details of this disaster are unknown.
 * The Witch/Witches (魔女, Majo): The Witch or Witches of the Kingdom are a disaster foretold to bring destruction to Lugunica. The details of this disaster are unknown. It is also unspecified if this disaster includes only a single Witch or multiple Witches.

Flying Dragon Cataclysm (飛竜災害, Hiryū Saigai): Flying Dragon Cataclysms are incidents in Vollachia where flying dragons completely destroy a settlement during their breeding season. However, this name was also used for an incident in the Fortress City of Guaral where Madelyn Eschart commanded a herd of flying dragons to lay waste to the city.

Slang and Language
E・M・?: Various shortened phrases Subaru uses to praise Emilia. These include E・M・B (Emilia-tan Maji Bosatsu), E・M・F (Emilia-tan Maji Fairy), E・M・H (Emilia-tan Maji Healer), E・M・K (Emilia-tan Maji Kishidou), E・M・K (Emilia-tan Maji Koakuma), E・M・M (Emilia-tan Maji Megami), and E・M・T (Emilia-tan Maji Tenshi).

Hornless (ツノナシ): A term for Oni who either have lost their horns or were born without them and Demon Beasts who have been tamed by theirs broken. For the former in this state, they cannot draw-in mana from the atmosphere nor sustain the use of it for long periods resulting in a weakened constitution. However they can survive with regular mana infusion from someone who knows the skill.

Hyena (ハイエナ): In the Kararagi City-States, this term is used to refer to people or demi-humans who have no home or anything to eat. They live life by scavenging in trash cans for things to eat. The term is thought to originate from Hoshin's time. Before she was taken from the streets, Anastasia Hoshin lived as a hyena.

Lolicon: A term that was used in Kararagi between Chuden and Ricardo in Anastasia's Kararagi Merchant Path, by the latter after the former mentioned it was "love at first sight" that brought Anastasia to him. The term was coined by Hoshin of the Wilderness 400 years ago and has become a common word in Kararagi since. Some theorize that Hoshin was a lolicon himself.

Apostle of Greed (強欲の使徒): A term and position given to those who have gained Echidna's favor. It grants them the "Command Authority" which forces compulsory obedience from all replicas of Ryuzu. There have been only 3 people who have held this title: Garfiel, Emilia, and lastly, Subaru. However, in Subaru's case, he lost his right as an Apostle in the middle of Arc 4.

Demi-Human (亜人 Ahito): The general term for all humanoid species such as Beast-Humans, Oni, Giants, Elves, various Reptilian races etc. They are found throughout the world, though some are unique to specific regions. Although their social status and treatment vary by country, with Gusteko being the worst. Many half-elves and similar mixed-bloods are particularly detested due to the similarities of their birth with the Witch of Envy, which has extended to demi-humans in general to a lesser degree.

Dragon Maiden: A position and title which will be given to the woman who wins the Royal Selection and becomes Luginca's ruler. Dragon Maidens have existed in the past, but back then they served only as intermediaries between the previous kings and Volcanica as part of the old contract.

Lion King (獅子王): A sage king whose uncanny intuition and leadership guided Lugunica to prosperity in the distant past before the contract between the Lugunica family and the dragon Volcanica which guaranteed the health and the security of the nation from external threats. Once the established country became known as the Dragon Kingdom of Lugunica and the royal family's coat of arms shifted from a symbol of the “lion” to that of the dragon. The former insignia came to pass over to House Karsten instead. Since then, the royal family had only needed to carry the bloodline to ensure the contract. While the de jure-wise wielded the highest authority in the land, due to their lacking statesmanship since then, their influence over state matters has waned from the days of the "Lion Kings". The effects of that led the general populace to look to the dragon and the Council of Wise Men more often than they would have otherwise for guidance instead. Every now and then a royal heir bearing the potential qualities to be the next "Lion King" would be born; unfortunately, every known person with the royal bloodline is now dead.

Shinobi (シノビ): Shinobi are skilled spies and assassins that are originally from Kararagi but are known to be employed by other powers.

Doctor: A person that is extremely skilled at using healing Magic and has passed at the Healing Insitute in Lugunica.

Blight Dragon (邪龍 Jyaryuu): A term used by the general population four centuries ago, to label dragons which did people wrong, by attacking, killing and hunting them. It is mentioned by Beatrice that this term is nothing more than a viewpoint of humans, rather than a designated species name. According to the legends, Blight Dragons were all but exterminated by the first Sword Saint Reid Astrea, four centuries ago.

Myon Myon: According to Echidna, a mage by the name of Myon Myon walked the lands long ago. Back then, magic wasn't systemised yet, so her pupils developed a habit of chanting "Myon Myon" when casting spells. This can be seen during the events of the second failed loop of Arc 2, when Roswaal examined Subaru for his potential in magic. Furthermore, Echidna had the habit of repeating the same chant when "downloading" Subaru's memories in Kasaneru IF Light Novel edition.

Worldbuilding
Consistencies include...


 * Kingdom of Lugunica National Foundation Day (ルグニカ王国の建国記念日): The 25th of the month Marshba (マルシュバ) of Laguna's history. Coincides with the Monthly Festival (月祝祭): Also on the 25th day of every month. Unsurprisingly, it is a monthly morning event celebrating the national anniversary of Lugunica.


 * Months: The world of Re:Zero has its own months, but only four are known so far in the story, "Tadmus", "Arbe", "Marshba" and Kisdam".


 * Seasons (季節): The seasons in the world are categorized into “Red-Sun, Blue-Sun, Yellow-Sun, and Green-Sun”, with each matching a different elemental magic type. According to Subaru, Red-sun refers to the equivalent of Summer, Blue-sun to Winter, Yellow-Sun to Autumn and Green-Sun to spring.


 * Time Tower (刻限塔) and by extension, Time: Time Towers are tall buildings with a time crystal placed in them, similar to a clocktower. Many cities and villages have them and multiple towers are placed within each one. The clock and Time, in general, are split into two phases, Brightsun and Darksun, which represent the elements of light and shadow. These are further divided into sub-section sections that correspond to the 4 primary elements with each representing 6 hours. Brightsun is Wind Time and Fire Time, ranging from 6:00 AM to 6:00 PM. Darksun is Water Time and Earth Time ranging from 6:00 PM to 6:00 AM. The crystals wane and glow with the passage of time to show the transition.

Facets of background politics within the Re:Zero world include...


 * Royal Selection (王選): See Royal Selection.

An election to decide on who will become the 42nd King of Lugunica. The elections span for three years until the same day, which falls on the month before the ritual to form a new contract between Volcanica and the chosen candidate. The five candidates are Emilia, Crusch Karsten, Anastasia Hoshin, Priscilla Barielle, and Felt, all of whom were chosen by the Dragon Insignias. For a more detailed explanation, see Royal Selection.


 * Divine Dragon Ritual (神龍儀): A ritual between Volcanica and either the king or a shrine maiden of the Kingdom of Lugunica where the pledge is reviewed. The next ritual will be held three years and a month after the beginning of the royal election.


 * Imperial Selection Ceremony (皇帝選出の儀): A method which the Vollachia Empire uses to determine succession to the throne. The “process” begins with the current Emperor conceiving children with people from all corners of the country. Those children are supposed to then vie for the throne, and the last known survivor becomes the new Emperor. This ceremony is an example of the Emperor themselves following the country's ideals, earning it the support of the people. It officially begins when the current Emperor is burned to death by the Yang Sword or otherwise loses their credentials. The Emperor's children are gathered together to test whether they hold the credentials by seeing if they can wield the Yang Sword without burning to death, hence signifying the time to fight for the throne has come. It's also possible to decline to take the sword and thus exclude yourself from succeeding the throne, however, such people are typically killed during the ceremony or when a new Emperor takes the throne. The ceremony typically lasts under a year.


 * Western Margrave Domain Meeting (西方辺境伯領会合): A meeting that takes place between people of notable influence regarding the rule of the Western Margrave Domain, the domain owned by Roswaal L Mathers.

Fauna within the Re:Zero world
Dragons (龍, Ryū): Dragons are usually very large and very powerful powerful creatures made entirely of mana clumps. In the days of the Witches, Dragons freely roamed the world in numbers. For more information, see Dragon.

Dragons (竜 Ryuu): Unlike the mana-based Dragons, dragons are smaller and less powerful beings with bodies of their own. They come in different species, such as earth dragons, water dragons, and flying dragons. The earth dragons are said to be created by the Divine Dragon after it blessed the grounds of Flanders. For more information, see Dragon.
 * Earth Dragon (地竜 Chiryū): Dragons created by Volcanica. Much like horses on earth, these wingless, land-based dragons are often domesticated to be used in menial labors such as transport or in warfare. They have varied body types and colours to suit different terrains, environmental conditions and jobs which makes them excellent to work with. All Earth Dragons are born with Wind Evasion a species-based Divine Protection. Specific species types known include Flanna (フランナ種), the most numerous versatile species, Eliq (エイリーク種), an earth Ddragon species for cold environments, Agaress (アガレス種), an earth dragon species for desert environments, and Diana (ダイアナ種), the species of Patrasche, a prideful and relatively rare species. The Diana species is the original species from which all other earth dragons descend from.
 * Flying Dragon (飛竜 Hiryū): A lesser species of dragon, like earth dragons. They are nearly impossible to domesticate, though some people in the Vollachia Empire had found a means to do it. These dragons have been shown capable of surpassing the speed of sound. It is likely that they are also born with a similar Divine Protection as with earth dragons and water dragons.
 * Water Dragon (水竜 Suiryū): A lesser species of dragon, like earth dragons. These dragons are aquatic creatures, with long serpentine bodies, with short stubby limbs. They have blue, slippery skin and have a head that resembles a dragon's. Their mouths are crowded by sharp fangs, and catfish-like whiskers extend from its snout. They are harder to domesticate than earth dragons, as one must be trained from the very day they hatch from their eggs in order to recognise someone as their master. All water dragons are born with a Divine Protection which protects them from the effects of the water.

Black Deer (黒鹿): It is a deer-like large herbivore which lives in Buddheim Forest in Vollachia. It is characterized by its strong horns and black furs. Its first appearance is in Re:Zero Light Novel Volume 27, chapter 1, part 5.

Liger (ライガー) Ligers have an appearance that is similar to wolves on earth. Ligers are a somewhat rare type of species, as they are often seen in Kararagi, but not so much anywhere else, and especially not in Lugunica. Ligers are very territorial, so they can be difficult to raise. They are often used by the members of the Iron Fang mercenary group for menial labors such as transport or warfare. Although they are similar to Earth Dragons, Ligers lack strength, but they are more agile and have higher speed and endurance. They have a high chance of winning if the two were ever needed to fight in a melee.

Falo (ファロー): Falos are animals with a quiet disposition with high stamina comparable to the likes of Earth Dragons or Ligers. They are valued in all countries, however, they have an element of cowardice in their nature. Long ago they were referred to by the name "Grim Oxen".

Galewind Horse (疾風馬): Galewind horse is a giant and horse-like animal in Vollachia Empire. Like horses on earth, they are used for riding or carriage. But since they are quite rare, they are typically used by generals in Vollachia.

Demon Beast (魔獣): Demon Beast is a general name for any number of organisms that are able to sustain themselves off of mana and have origins of creation from the Witch of Gluttony. Under most conditions, they are larger and stronger than regular fauna and typically possess often hazardous magical abilities. See Demon Beast for more information.

Demi-Beast (亜獣): Demi-Beast is a general name for any number of organisms that are a cross between flesh and inorganic objects, with weapons like axes or spears protruding from their bodies and have their origins of creation from the Sin Archbishop of Lust. Interestingly enough, they are unrelated to Demon Beasts. See Demi-Beast for more information.

Undead (屍人): Undead is a general name for corpses reanimated by Sacrament of the Immortal King, a magical curse art that allows a caster to control the bodies of the deceased. They are also known as zombies (ゾンビ) and corpse soldiers (屍兵).
