Terminology

A page explaining the various terms used in the context of the Re:Zero universe.

General
The Great Calamity (大災厄 Daisaiyaku): A critical event that occurs 400 years before Natsuki Subaru is summoned to the 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 Flugel, Reid Astrea, Volcanica and Shaula.

Silver Flower Dance (銀華乱舞): A series of notable duels taking place in the city of Picoutatte between the “Sword Demon” Wilhelm Trias, and the warrior Kurgan. Both of the men were fighting on behalf of their country, Wilhelm fighting for Lugnica, and Kurgan fighting for the Vollachia Empire. Despite taking relatively heavy injury, Wilhelm Trias would walk out as the clear victor, cutting off six of Kurgan’s eight arms.

Demi-human War (亜人戦争): See Demi-human War

Emperor 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 women 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 himself 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 his 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 Territory 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 Territory, the territory owned by Roswaal L Mathers.

The Great Expedition: See Great Expedition

The Day of Red Earth and Sky: Seven years before the main story, Puck unfroze Emilia from the ice she was imprisoned in. It was only a half year later when Melakuera 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 against him. Ultimately, Elior Forest became the battleground of Melakuera and Puck's battle, with the latter being the victor of that battle. That day became infamously known across Lugnica as the "Day of Red Earth and Sky".

Earth Dragon (地竜): 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 colors 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 Water Dragon (水竜): A lesser species of dragon, like Earth Dragons. Water Dragons are aquatic creatures, with long serpentine bodies, with short stubby limbs. They have blue, slippery skin and have the 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. All Water Dragons are born with a Divine Protection which protects them from the effects of the water.
 * Flanna Species (フランナ種): The most numerous versatile species.
 * Eliq Species (エイリーク種): Earth Dragon species for cold environments.
 * Agaress Species (アガレス種): An Earth Dragon Species for desert environments.
 * Diana Species (ダイアナ種): The species of Patrasche. It's a prideful and relatively rare species.

Winged Dragon (翼竜): 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. It is likely that they are also born with a similar Divine Protection as with Earth Dragons and Water Dragons.

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 Lugnica. Ligers are very territorial, so they can be difficult to raise. They are often used by the members of the Fang of Iron 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 to 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".

Food: Various foods are known by different names, such as Ringa (リンガ) for apple (ringo), Lemom (レモム) for lemon, Solte (ソルテ) for salt, Peppa (ペッパ) for pepper, Vinegee (ビネギー) for vinegar, and Pimaru (ピーマル) for bell pepper (piman).
 * Fluffy (フワフワ): Fluffy is a famous cotton candy-like thing sold in the capital of Lugnica. Fluffy made by first-class craftsman is good enough that they can't be told apart from clouds in the sky.
 * Coff (コーフ): Coff is a drink that is made from beans that are transported and made in the Vollachia Empire. In the side story Rem's Latte Art, Subaru claims that coff is actually just something which is similar to coffee.
 * Ryokucha (リョクチャ): A popular drink created in Kararagi.

Kingdom of Lugnica 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 Lugnica.

Demon Beast (魔獣): See Demon Beast.

Demi-Beast (亜獣): A kind of species that appeared after the flooding of Priestella. Interestingly enough, they are not related to Demon Beasts. The beasts are described to be a cross between steel and flesh, having weapons like axes, spears, and such protruding from their body. Most are blind and lack certain body parts. The beasts are Capella's creations, of which, she heavily implied that they were made from corpses. It's left unclear whether her Authority resurrects the corpses and transforms them, or if she does it moments before their death.

Witches of Sin (大罪魔女): See Witches of Sin.

Witch's Miasma: Also sometimes called the "Witch's Scent", is an invisible air that exudes from those who hold the power of witches or are connected to them. The Witches of Sin, the Archbishops of the Witch Cult and Demon Beasts 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. The miasma is normally harmless when it is in small doses, however in high density it will start having an effect on living things like people and beasts by driving them into madness. 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.

Demi-human: 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. 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-humankind in general to a lesser degree.

Magritza's Guillotine (マグリッツァの断頭台): A book which Beatrice was reading during the second Arc. It's classic Vollachian literature which originates from a tale about a character named Magritza. There are noticeable scenes such as the "interaction between an old disciplinarian and the preceding King" and "The old king who deceived his disloyal attendants and allows assassins he hired himself to sweep him away." At the end of the story, the hero who conspired with the Father King is guillotined.

E・M・?: Various shortened phrases Subaru uses to praise Emilia. These include E・M・B (Emilia-tan Maji Bara), 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).

Royal Selection (王選): An election to decide on who will become the 42nd King of Lugnica. 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.

Dragon Insignia: A small ceremonial touchstone badge with inset a red jewel in the middle. During Royal Selection, it marks those who have the qualification and potential to become the Dragon Maiden and as well as Lugnica's next ruler, signified when its jewel shines brightly. There are 5 in total and all were first given to the royal family of Lugnica at the same time as the Dragon Tablet.

Dragon Tablet: A large stone lithograph bequeathed by Volcanica to the late royal Lugnica family that could foretell the fate of the country. It acts as a guideline to shape Lugnica's future. For example, the idea that the Royal Selection would be held to choose a new ruler and the specifics came directly from it.

Lion King (獅子王): A sage king whose uncanny intuition and leadership guided Lugnica to prosperity in distant past before the contract between Farsale Lugnica and Volcanica was made which not only guaranteed it but its safety as well. Once the established, country became known as the Dragon Kingdom of Lugnica and the royal family 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 and while they still wielded the highest authority in the land, due to their lacking statesmanship since then has waned their influence over state matters much compared to back then as people looked more to the dragon, and the Council of Elders for guidance. Every now and then a royal heir bearing the potential qualities to be next "Lion King" is born.

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.

Mana: A type of 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 is thought to originate from the Od Laguna.

Gate: An invisible portal-like apparatus that exist 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 defective gates which 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 life energy that dwells inside of a living being from birth, 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 serves the purpose of storing some portion of mana that flows through the gate, 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.

Od Laguna (オド・ラグナ): The Od Laguna is a storage of mana located at the origin of the world. No one knows where it is located or whether it has a will of its own. It is said that those who awaken to prohibited arts have had their spirits destroyed by looking at it. Some speculate that it is the world's will and gives Divine Protection to people. Its main purpose is to regulate the flow of souls and memories in the world.

Mana Poisoning: a state in which an individual continues to absorb an excess amount mana beyond their capacity, but is incapable of releasing it, which will eventually destroy their Od and kill them. Improperly configured or detective gates can also bring about 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.

Lagmite: Otherwise known as mana stones. They come in all six elements and serve many practical functions in society. I.e fire lagmite or stones can be used in mechanisms for cooking or heating baths. Light lagmite or stones can be used for portable lamps. Any living being that has a "Gate" can come in contact and use them. They do not need to be able to use magic themselves.
 * Pyroxene Crystal (輝石結晶): A colorless type of lagmite crystal that forms naturally through accumulation of mana turning it into a pyroxene. 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.

Contract: A type of pact between people or beings. The methodology and complexity differ depending on what individuals are involved. One of the most well known examples of contract is one between spirits and a special type of people who have the inborn talent to connected to them spiritually and become Spirit Users, mages who fight with spiritual arts. With spirits there are two kinds of pacts that can be formed Formal Contracts and Provisional Contracts. With "Formal Contracts", the spirit becomes fully attuned to the contractor's gate and they carry several conditions that must be followed by the contractor to maintain their relationship. These terms can range anywhere from complex tasks to fairly trivial ones, but all of them are treated with equal weight and if broken the spirit will become unbound. It is also implied some amount of mana and good compatibility with the involved parties is needed. "Provisional Contracts", are temporary pacts that unlike standard ones, come with no conditions beyond the main reason they were formed and require no inherent elemental mana compatibility of the same type between the contractor and the spirit or spirits. However as a downside these contracts are fragile as they offer little resistance against external forces such as other more powerful spirits who can override them with their own. Moreover they lack the ability to bring out a spirit's power to the utmost. Contracts between people and non-spiritual entities are less complicated in that they are made without extra conditions but both parties need to agree with the terms and conditions to establish it as long as the agreement is still in place. However if one of the individuals reneges on their side of the agreed terms, they will suffer penalty if it is magic binding, depending on the nature of the wager. It is noted that before legal codes for contracts where created, swindlers abused contracts to ruin others for their own gain without the other party being aware. Even in the current era although difficult to do, it is still possible unknowingly bind or manipulate a contract on someone through wordplay if the sorcerer is skilled enough in the use of contracts.

Karnago Powder (カルナゴの粉末): Powder with a strong odor that can erase a person's body odor along with the powder's smell within minutes if applied to the body.

Warning Stone (警戒石): Warning Stones are capable of alerting people of intruders.

Night Banisher: A special type of ammunition composed of a mass of condensed light lagmite. It can be fired from mana-crystal cannons into the sky to generate an artificial sun that lasts for an hour. A drawback is that it so bright it will blind anyone who has their eyes open during its initial activation.

Crystal Lamp (結晶灯): Crystal Lamps gather mana from the atmosphere during the day and can be lit at night by using the accumulated mana.

Time Tower (刻限塔): 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 Solartime & Lunartime which represent the elements of light and shadow. These further divided into sub-section sections that correspond to the 4 primary elements with each representing 6 hours. Solartime is Wind Time & Earth Time aka A.M. Lunartime is Water Time and Fire Time P.M. The crystals waning and glow with the passage to show the time transition.

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 consciousness 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.

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

Anti-Mana Crystal (退魔水晶): A type of crystal that can neutralize or dampen the presence of mana by forcing the energy back into a colorless state where it becomes dominant and invisible. As long as it is in effect, any power related to mana such as magic is weakened. Several of these were used against the Hakugei's mist to thin it out.

Dragon's Fang (龍の牙): A tool used in summoning Valgren. According to Stride, if the fang sucks the blood of heaven sent children, a blood crazed dragon will appear. He summoned the dragon using the blood of 20 Lugnican citizens.

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

Bokko Fruit: A small purple nut that can stimulate mana within a person's gate when taken. It's mainly used in emergencies when a Magic User's internal mana is depleted and their gate becomes dominant but needs to use magic. However because this forcibly reactivates gate it carries a serious risk of damaging the gate itself.

Fannel Fruit (ファネルの実): The Fannel Fruit is a small fruit that when taken as powder can make a person's body feel hot, make them honest, and bring about strong drowsiness.

Book of Wisdom (叡智の書): The Book of Wisdom is a white book crafted by Echidna that allows her to draw knowledge from the world's memory. 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.

 * Witch Cult's Gospel (魔女教徒の福音): Incomplete 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.

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.

Races
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. The currently the only known elven community to appear in the story is frozen in the Great Elior Forest.

Oni (鬼): The Oni are one of the strongest races of Demi-humans known for their strong bodies and mana quality. However as price for their strength, they have the lowest population among humanoid species and order to preserve their purity and pride enact strict taboos and live in villages in the mountains away from others. Most Oni have two horns that are activated by their demon instincts to consume and control the mana in their surroundings to enhance their fighting abilities. However there do exist those with only one or even no horns the later which are known "Hornless", considered the dregs of their society because of it. Moreover Oni born that way are to be killed by tradition to protect the Oni's pride as powerful and nearly perfect species. The village Ram and Rem lived in 10 years prior was the last Oni village, effectively making them the only two Oni left in the entire world. Roswaal remarks that the Oni's demise was because of natural selection, as they refused to accept new ideas, and not because of discrimination or prejudice.

Abilities
Magic (魔法): See Magic.

Witch Factors (魔女因子): Witch Factors are special, abstract factors that enable people to use authorities.

Divine Protection (加護): See Divine Protection.

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

Curse: 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 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 major one restriction in that it can work people have blood relations to the caster rather than just anyone. The spell was originally created by Echidna to gain immortally, but she could not complete before falling at hands of Witch of Envy. Instead it was finished by Roswaal who had been using it survive until the present era.

Magic Circle: 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 temporary 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 less are capable of using it. Magic Circles were deployed frequently by demi-humans during the civil war.
