Emilia

Subaru fell in love with her at first glance, largely due to her being the first one to show him kindness when he was transported to the new world. He devoted himself to protecting her no matter what happens to him, even if that meant having to repeatedly go back in time by dying. Initially, she didn't understand the meaning of his playful flirting with her, but gradually she nevertheless developed reciprocal feelings for him and even became jealous if she saw his "interest" in other girls. Their relationship is one of the main themes of the series and, in fact, the main reason for Subaru's development as an individual, because thanks to her, he gradually got rid of his impulsive personality and learned to be more reliable, judicious and useful person than how he was at the beginning of the novel. Later Subaru officially became her knight which symbolizes the strong bond of trust she has developed towards him.

Satella

Satella is the one who granted Subaru Return by Death and also stands behind his summoning to the new world. Originally, Subaru harboured intense hate and fear for the Witch but upon finally meeting her face to face in the Witches' Tea Party and coming to understand her intense emotions with the help of Carmilla's Authority of Lust, Subaru promised her that one day he'll find her and save her no matter what, despite Satella's initial request to kill her. In the prologue of the 9th volume, Subaru shows mutual and intense feelings for Satella which gradually turned into (and were described) as representing each of the seven deadly sins, starting from sloth and ending with jealousy.

As already mentioned, The Witch of Envy stands behind Subaru's Return by Death. Whenever Subaru breaks "their promise", Satella preforms some type of punishment, either by crushing his heart, or on an extremely rare occasion, crushing the heart of Emilia. In Arc 6, Satella repeatedly caused the destruction of the Pleiades Watchtower and killed everyone in it, as long as Rui Arneb was latched onto Subaru. 

Puck

Subaru has a relatively positive friendship with Puck, likely stemming from the spirit's friendship with Emilia. However, in a loop where Subaru accidentally killed Emilia by telling her about Return by Death, Puck angrily froze him to death for breaking his promise with Emilia, returning to the mansion against her wishes, and being the one that killed her.

Beatrice

Subaru and Beatrice initially had an antagonistic relationship. Subaru's personality often annoyed Beatrice, leading her to always mock and insult him. Subaru however began to rely on Beatrice for knowledge and advice and exclaimed how close they are. While Beatrice's actions had implied the friendship was one-sided, she did to an extent cared for Subaru as she cured him of his curse and foretold him about his death and how he could avoid it. She willingly made the contract to protect him from any potential threats to his life and defended him from Ram and Roswaal's attacks post Rem's death. After she became his Spirit partner, she started to open up to him.

Rem

After initially starting out on a bad foot, Rem eventually comes to fall for Subaru after he ends up emotionally and physically saving her during the events of the second arc, where afterwards she began devoting herself to him. After she confessed and won over a part of his heart after her numerous efforts to support him in the third arc. Subaru even agreed to take Rem as his second wife, but only if Emilia would allow it. In the fourth arc, he admitted to Emilia that both her and Rem are very precious to him, though Emilia still remains first for him. Subaru was heartbroken to discover that Rem had fallen into a hibernation-like state and that not even his Return by Death could save her. However, he pressed forward knowing that would have been what Rem would have wanted him to do and in the hope that he can one day free Rem from her slumber, After freeing Rem from her sleep she did not remember anything and was unable to trust Subaru due to his strong smell of miasma and his dubious attitudes.

Ram

Ram has a rather amicable relationship with Subaru despite the constant disparaging remarks she throws at him. During his time as a butler, she was in charge of teaching him about their daily duties. She even took the time to teach him how to write so he became more accustomed to life at the manor. Ram was also the first person to vouch for his character when it came to the possibility of him being a spy even when his past was still virtually unknown. Despite harshly assessing his skills as a butler, she nevertheless held a sense of fondness for him as her junior colleague. Ram would later come to trust Subaru's intuition even if the likelihood of the scenario had no basis due to his unexpected successes. Although they both hardly mention it, they both care very much for each other's well-being and they are both good friends.

Roswaal L Mathers

Subaru was originally impressed by Roswaal, admiring him as the head of Roswaal Manor and Emilia's primary benefactor despite the mage's eccentric behaviour. After the event of Arc 4, however, he realized that Roswaal is actually an egoistic and cruel person dedicated solely to reviving his master. Among Subaru's allies, he is the first to figure out that Subaru is looping through some method, though he never understood in what exact way. After Subaru defeated Roswaal in their challenge, Roswaal has agreed to help him but has also threatened to force Subaru into undergoing another loop if he makes a mistake.

Otto Suwen

After Subaru saved Otto from financial ruin and offered him a job as the minister of interior affairs for the Emilia Camp, the two became steadfast friends. Though their relationship has involved Subaru light-heartedly teasing Otto, the two of them are still rather loyal to each other, with Otto always having his best interests for Subaru in mind. Furthermore, Otto is one of the people Subaru trusts the most, and usually always talks to him first, before making any important decisions.

Garfiel Tinsel

Subaru helped Garfiel to understand the truth about his mother and became good friends with him. Despite his fights in the past, Subaru was still willing to talk to him. Their relationship eventually blossomed to that of a loyal subordinate and his captain, their camaraderie tied by not only that but also deep friendship.  

Though Garfiel knows that Subaru doesn’t have the same physical strength as himself or other warriors, he highly respects his judgment, even if that includes having Garfiel take on a dragon.

Ryuzu(s)

In Arc 4, Subaru and the Ryuzus all seemed to get along. When concerning matters about Garfiel, the ones with strong self-awareness - Alma, Bilma, Shima, and Delma - they would inform him of what happened in the past, and they would trust him with their concerns for the boy, even trusting him to help set Garfiel straight. Though, Shima was at first a little wary since she could sense the Witch’s scent on him.

After the events of Arc 4, they, along with Garfiel, would end up giving names, different colored ribbons, and differing hairstyles to the Ryuzus without much self-awareness in order to help them grasp a better sense of their own identity. In particular, the clone known as Pico seemed to be particularly attached to Subaru throughout Arc 4.

Petra Leyte

Subaru has an amicable relationship with Petra, though he does not realize that she has a crush on him. He often tries to take her worries into account to the best of his abilities.

Meili Portroute

After Elsa Granhiert's death, Meili was captured and was locked up under new Roswaal Manor. Subaru forgave her and gave her a panda to convince her to help him out. During the events of the 6th Arc, the two of them grew closer and closer, to the point Subaru asked her if she'd join their camp. Meili views Subaru almost as an older brother.

Felt

Subaru met Felt in the first loop when some thugs assaulted him but Felt didn't help. Later on, she was about to get killed by an assassin but got saved by Subaru. From there, they both established a friendship. Sometime later, when they met again in the Royal Capital, Felt showed that she was still making fun of him. As their friendship deepened, she respectively refers to Subaru and Emilia as big brother and big sister.

Reinhard van Astrea

Upon first meeting Reinhard, Subaru immediately recognized him as someone who has been chosen by God himself. Originally jealous of his gallantry and manliness, Subaru did not waste much time and started his soon-to-be-necessary relationship with him on a good note. As it later turned out, Reinhard's presence was vital in overcoming the Loot House incident and defeating Elsa while saving Emilia's life and returning her stolen Insignia. Despite being better than Subaru in every way imaginable, Reinhard considered Subaru to be his equal; even more so after Subaru defeated the Hakugei, liberated the Sanctuary and played a vital part with retaking of the Watergate City of Priestella, having been the key card in taking out the Sin Archbishop of Greed.

Currently, both Reinhard and Subaru harbour immense respect towards each other, with both of them swearing to each other that they'll fill the other party's shortcomings; Reinhard will play the role of a sword and Subaru will play the role of the tactician. They both consider each other as good and reliable friends.

Rom

Subaru and Rom are on mutually friendly terms with one another. Although he thinks that the old man is somewhat like a villain, Subaru finds it hard to dislike Rom.

Crusch Karsten

Subaru has fostered a good alliance with Crusch after the success of killing the Hakugei, with Crusch even giving most of the credit of the victory to him. After her memories were eaten by Lye Batenkaitos, their relationship became somewhat neutral, but leaned toward friendly.

In Arc 5, the two would meet again on friendly terms. Not long after, however, the Witch Cult attacked Priestella, forcing the Royal candidates to fight back. Deciding to ignore his injury, Subaru would join the task force to retake City Hall, where he and Crusch would fight sight by side. The two would repetitively save each other and fight as equals, Crusch jumping to push Subaru out of the way from Lust’s flames, and Subaru using the remnants of his fading consciousness to tie her to the foot of the transformed Garek Thompson, who had attempted to save them, to keep her from falling.

Back at City Hall, when Crusch would request to see him, he would end up feeling terrible about not being able to prevent her from contracting the curse from Lust. Similarly, he would be ashamed of himself for wanting her to blame him, when in reality, she was worried for his safety. Shortly after, though, he would discover that he could transfer the curse from her to himself, albeit painfully and at an unfair rate. He would be fully prepared to take the curse from her, but she pleaded with him not to, believing that the people needed him more than herself, and asking him to tell her to “leave everything to me”, to which he did, albeit hesitantly. Subaru is still resolved to take in the curse in the future if there is no other alternative.

Ferris

Although Subaru did not particularly see Ferris in a negative light, due in part to his prior meeting with Subaru, his outburst during the Royal Selection’s start, and Ferris’s own hatred towards being weak, Ferris did not like him all that much. In fact, when Julius “helped” Subaru via their bout, Ferris questioned why he went so far. Later, however, when Subaru came to negotiate with Crusch for her assistance, his view of him improved, and a short time later, he would even compare Subaru to his late friend. In fact, this view would improve even more as they fought alongside each other against the Hakugei and Sloth. During one failed loop, Ferris even cried that he was forced to use his power to help end Subaru’s life.

Approximately one year later, their friendship would remain intact. However, thanks to the attack on Priestella and Crusch being cursed by Lust, Ferris would lash out in anger, not even Subaru escaping his scornful voice. Of course, due to the circumstances, this would not affect their relationship.

Shortly thereafter, when Subaru discovered that he could remove Crusch’s curse by transferring it into his own body, Ferris was conflicted with Crusch not allowing him to take the rest into his body. After she finally fell asleep, Ferris would turn to Subaru to ask what he should do, to which Subaru had to remind him of his duties, in spite of what they both really want.

Wilhelm van Astrea

Subaru views and respects Wilhelm as the very ideal of a man. Although the two did not Subaru helped the Sword Demon in avenging his wife, Theresia van Astrea, by participating in the subjugation of the Hakugei. Wilhelm gained respect for Subaru after this, and in turn, he helped Subaru defeat the Sin Archbishop of Sloth. Subaru was considerate enough towards Wilhelm by attempting to heal his relationship with Reinhard and letting him confront his wife after discovering that she was a revived corpse soldier in Priestella.

Anastasia Hoshin

Subaru and Anastasia's relationship is somewhat complicated. In one loop where Subaru accidentally told information about Crusch's Camp she abandoned him after revealing that she was actually using him. Despite this, Subaru still saw her as a key potential ally alongside Crusch during the campaign to subjugate the Hakugei.

A year later, he would work alongside Anastasia, acting as a general of sorts in the resistance of the Witch Cult. The two would recognize each other’s leading skills and trust each other’s judgment. Following Subaru’s speech to the people of Priestella, Anastasia would even find herself invigorated by his words. Thanks to these interactions, Subaru would be one of only a few people to recognize that “Anastasia” was not Anastasia towards the end of the arc.

Following the events of the following arc, Anastasia would go out of her way to cross two countries to help retrieve Subaru from Vollachia, where he’d been teleported away.

Julius Juukulius

Subaru and Julius started with off on a bad note, due to Subaru rash acting at the Royal Selection and offending the whole Royal Knight garrison, which Julius was unable to accept. While both had apologized to each other after the battle with the Hakugei. Despite that, Subaru had told him that he still hated him, to which Julius stated that he didn't think they could be friends. After Julius' name was eaten by Roy Alphard, their relationship has gotten somewhat better and they both became close friends with a strong mutual liking and respect which was shown during their trip to the Pleiades Watchtower.

Ricardo Welkin

Subaru first thought of Ricardo as a very annoying guy. Throughout the battle with the Hakugei, Subaru realized that Ricardo was looking out for him. During the fight against the Hakugei, Ricardo saved Subaru by taking the hit and sustaining major injuries in the process. In exchange, he gave Subaru a message which in turn helped Subaru realize the trick behind the Hakugei's multiplying ability that allowed Subaru and Crusch to create a plan and defeat the giant Demon Beast.

Eridna

They first officially met when Subaru confronted “Anastasia” at the end of Arc 5, and when he heard the artificial spirit claim the name Echidna, he was instantly hostile to her, to her surprise. After getting across that she was different from the Echidna he knew, he would at least listen to what she had to say, though due to her demeanor being an exact match for her creator, he couldn’t trust her in the slightest. Ultimately, the two decided to work together during the expedition towards the Pleiades Watchtower.

Shortly after entering the tower, Subaru and Eridna would talk to each other on the balcony, where Eridna would ask him who he was, having been unable to find out when Anastasia looked into his background. Subaru would notice her clenching tightly to her clothes, indicating fear of him, which had only intensified over the course of the last two arcs.

However, close to the conclusion of Arc 6, it seems that his relationship with Eridna has somewhat improved, though the extent of that improvement is unknown.

Priscilla Barielle

After initially seeing how she treated Emilia during the Royal Selection's commencement, Subaru began to dislike Priscilla and found himself enraged at her arrogance. While Subaru finds her mood swings to be terrifying and generally regards her as untrustworthy, Priscilla regards him as a commoner and fails to evaluate him highly, even claiming to not recognize him in the beginning of Arc 5. However, it can be assumed that she is paying some form of attention to him, as later during the very same arc, she mutters a comment about his “always having good timing”. The extent of the attention she pays towards him, however, is unknown.

Al

As Al works under Priscilla as a servant, Subaru's relationship with him is complex. He views Al as a senior with more experience in the new world he finds himself in, yet Subaru is unable to immediately trust him due to his affiliation with Priscilla.

In arc 5, Al would be the one to back up Subaru when the group was discussing who should give the speech to calm Priestella and raise its morale, reminding them that Subaru was not some Superman that could handle every burden that came his way. Ironically, it would be Al’s words that inspire Subaru to give the speech, though Al warned him of what that meant.

In arc 7, it would be Al who would encourage a depressed Subaru, telling him to earn the words that were revoked back. Deciding to assist him with this, he would follow Subaru to Chaosflame. During their travels, Subaru would come to trust Al much more than before.

Furthermore, Al fully believes in Subaru as this world’s hero. In arc 8, with this belief firmly in mind, he made it his goal to pave the path for Subaru’s arrival believing him to be the person needed to defeat the Great Disaster.

Heinkel Astrea

Despite how the two have only met once, Subaru immediately thought that Heinkel was an unpleasant man who embodied the very face of malice itself. After hearing about his history from Julius and discovering how he held Felt captive in an attempt to guarantee his own safety, Subaru's feelings about Heinkel's personality were further diminished.

Shaula

Initially, Shaula did not give any special attention to Subaru, attempting to snipe him and the other members of the Pleiades Watchtower expedition team as per her master’s orders (succeeding in two loops). However, after Subaru inadvertently broke the barrier that sent him and a few of his comrades beneath the sand, Shaula ceased her attack and immediately went to greet him, suspecting him to be her master.

After he woke up from being saved, he immediately met Shaula who, despite appearing intimidating at first, instantly pounced on him and would not let go. Claiming Subaru to be her master thanks to her sense of smell, she was willing to follow all of his orders. Of course, Subaru had no clue what she was talking about and stated multiple times to her that he was not her master.

During the stay at the watchtower, Subaru grew close to Shaula and wished to take her out of the tower. However, after one of the rules of the tower was broken, she was forced into her Crimson Scorpion form and began attempting to kill him. Unfortunately, following her defeat, she was left in the state of a tiny scorpion without a proper mind of her own, leaving Subaru heartbroken.

Vincent Abellux

Vincent and Subaru first met at the starting point of Arc 7. Though wary of Subaru's intentions, Vincent soon realised he wasn't in danger, letting his guard down and even helping him. Vincent even went as far as gifting Subaru a dagger with a Vollachian symbol embedded in it. The dagger later came to serve Subaru rather well, as he used it to cut his way through dense flora in the Buddheim Jungle as well as unknowingly getting on Todd's good side as the Captain thought Subaru was a Vollachian noble. Later Subaru and Vincent managed to get themselves entangled with the People of Shudrak, being forced to partake in the Ritual of Blood. After successfully defeating the giant black snake Demon Beast, Vincent asked Subaru to assist him regain the Imperial throne again.

Subaru and Vincent often express their disagreement for each other's way of thinking as their mentalities continued to heavily clash against each others'; Subaru's idealistic and hero-like mentality could not comprehend Vincent's ruthless and cold, yet calculative tactics, and the fact he's willing to throw away innocent lives to further his own goals. With time, however, the two started to see eye-to-eye. Vincent started relying on Subaru as some kind of strategist, though Subaru is somewhat indifferent to Vincent, as he doesn't wish to view himself as his ally or accomplice.

Cecilus Segmunt

Subaru would first meet the infantilized Blue Lightning in Ginunhive. Their relationship was rather strange, as Subaru was often left dumbfounded and exasperated with Cecilus’s point of view and actions. However, he would recognize his strength as unbelievably dangerous. Meanwhile, Cecilus sees something special in Subaru, even going out of his way to pull him and Tanza from the waters that surrounded the island and stake his life on his bet with Gustav. When Subaru would restart from zero at Ginunhive, he would better understand how to deal with Cecilus, and he would save requesting his assistance for last, simply to get on his nerves.

Cecilus often uses words from Subaru’s home world, having grown fond of and enjoying the words. In fact, he would ultimately end up referring to Subaru as “Boss,” respecting his leadership of the Pleiades Batallion. He also seems to notice something strange about Subaru, referring to what he has as “true sight.” The two would make a promise under the moonlight to not use their respective strengths to save each other, but both of them knew that they would readily break that promise if the other party was in danger of dying.

Olbart Dunkelkenn

Subaru does not like the old man, but he is fully aware of his strength. In fact, it would be because of Olbart that Subaru would experience the “ten seconds of despair,” causing him to hold a grudge against him. It is unknown how Olbart felt about him following the false “Great Disaster” in Chaosflame.

When they were forced to work together to push back the Great Disaster, Subaru tasked Olbart alone with invading the restructured Imperial Palace. Upon entering and realizing the drastic changes, he believed Subaru to have already foreseen this turn of events, leading Olbart to believe his foresight useful yet dangerous for the future.

Yorna Mishigure

Initially, Subaru did not have a very good impression of the woman, comparing her to Priscilla. However, he would come to respect her after meeting in his infantilized state, recognizing her as a kind woman who cared for children and the residents of her home. He would even feel gratitude towards her for the numerous times that she tried to save him over the “ten seconds of despair.” When he would be forced to retreat from Lupugana, he would be worried for her safety when he learned she was left behind.

Zikr Osman

Though the two met while Subaru was under the guise of Natsumi Schwartz, even after discovering he was male, Zikr treated him with respect and referred to his by the name Natsumi. When Subaru vanished following the events in Chaosflame, Zikr was worried for him.

Jamal Aurélie

Jamal was one of the first people that Subaru met in Vollachia, and they were immediately antagonistic to each other. Like Todd, Jamal thought of him as a dangerous enemy, only being backed by the falls of the Buddheim military camp and Guaral.

They would meet again later, though Jamal probably does not recognize Subaru as the same person due to the infantilization. Despite his mouth, he was grateful yet apologetic that Subaru was the one who had to give his sister the news about Todd’s supposed death. Later, the two would be forced to work side by side, albeit reluctantly, and when Jamal stated his intention to fall in battle to support his sister, Subaru was against this and told him he wouldn’t allow the soldier to die.

Mizelda Shudrak

Their initial meeting was not the greatest, Subaru having been placed in a cell for trespassing in their territory alongside Vincent. However, he would garner great respect from the woman during the Lifeblood Ritual, becoming a warrior in her eyes. Naturally, believing that this fight would be his last, she and the other Shudrakians would go to save Rem for him. That said, having survived, her respect stayed, and she was willing to help him like Vincent as if he was one of their own.

Taritta Shudrak

Subaru and Taritta get along fairly well. Although they started out rockily, she would come to respect him like her sister would and consider him as one of their own. Later, on the way to Chaosflame, she would reveal to him her insecurities towards being entrusted with the title of Chieftain, even claiming some envy towards Subaru’s boldness when posing as “Natsumi Schwartz.” Wanting advice from him, Subaru would tell her that it’s fine to run away if she wanted to, comparing his own insecurities to her own. He claimed it would be selfish if he told her to be strong and accept it, and that it would be telling her to numb her feelings, which he felt would be wrong. Ultimately, though, she would end up not running, and she would be thankful towards him.

Taritta has been conflicted with Subaru before, what with the prophecy that was given to her by her late friend, Mariuli, which would lead her to attempt to kill Subaru. Subaru is currently unaware of Taritta being “the Hunter” who shot him during his first failed loop in Vollachia. However, whether this would effect his views of her is unknown.

Flop O'Connell

Subaru would first meet the kind merchant in Guaral, where he would assist Subaru’s group in entering the city. Similarly, he would go out of his way to save Flop from the ruthless Todd, having witnessed him give his life so that Subaru could escape. Ultimately, Flop would join Subaru in the retreat from Guaral, and he would even help him with the Bloodless Siege that followed. Ultimately, the two harbor a great respect for each other.

Medium O'Connell

Like her brother, Subaru would meet the excessively optimistic Medium when she and her brother helped them into Guaral, and like Flop, she would also escape with Subaru. Later, the two would travel to Chaosflame together. Being entrusted with this task by her brother, Medium gave her all to help Subaru and Vincent. Like with her brother, the two harbor a great respect for each other, Medium even going out of her way to help comfort a distressed Subaru in their infantilized states.

On their way to face the Great Disaster, Medium thanked Subaru for meeting her and her brother in Guaral, believing that thanks to that, she wouldn’t have met all the kind people she had, nor would she be given this chance to speak with an old friend. Likewise, Subaru felt the same, believing that she was a great help to him, just like he was to her.

Tanza

Subaru’s relationship with Tanza wouldn’t begin until Ginunhive, where the two were teleported following the conclusion of the events in Chaosflame. There, the two had aligning goals, forcing them to work together. Though Tanza would often find herself exasperated with his actions, she would come to gain a great respect for him. In the failure of Ginunhive, with Subaru’s authority seeming to malfunction, she would even cry as Subaru was dying in her arms.

Like Gustav, Tanza would act as Subaru’s advisor in the Battalion, and at times, like a battering ram, much to her annoyance. However, because Subaru trusts her with these tasks, she will let the slights slide. She also tends to worry about him, especially when he seems to ignore her feelings on certain matters. However, he does listen to her, and he will trust her with tasks that align with her wishes, such as confronting Yorna in the zombie-infested Lupugana.

Gustav Morello

Subaru respects Gustav, who, with everything he was capable of, tried to maintain peace and order on Ginunhive, in deep contrast to how it apparently used to be. Not including Cecilus, Subaru would save convincing Gustav for last, believing him to be the hardest to convince. After challenging him to a “Sparka,” Gustav, who had rather complex views of Natsuki Schwartz, decided to become Subaru’s ally. In the Pleiades Battalion, he would act as Subaru’s advisor of sorts.

Hiain, Weitz, and Idra

The members of Subaru’s unit started off completely uncooperative, but they would eventually come to harbor great respect for Subaru. This has gotten to the point where they have become essentially his lieutenants in the Pleiades Battalion. They will fight by Subaru’s side, come hell and high water, as seen when they each gave their lives to protect him during the failure of Ginunhive.

Halibel

These two are friendly with each other and respect each other. Having seen an example of Halibel’s strength on the coupled dragon carriage, he couldn’t help but be left amazed. When he was requested to assist Subaru in reclaiming Lupugana, Anastasia asked the wolf man to listen to Subaru as much as possible. He would listen to her, and when he realized why he was sent to handle Eugard Vollachia instead of the dragon, he recognized Subaru’s foresight.

Elsa Granhiert

Although he initially found Elsa bewitching, Subaru would soon come to the the conclusion that she was out of her mind. He loathed and feared Elsa for her inhuman skills and for finding pleasure in murdering other people.

Todd Fang

Upon their first meeting in a previous loop, Todd and Subaru were on friendly terms. Subaru thought that Todd was a nice guy and thought well of him. However, that would quickly change in their subsequent meeting, where Todd would instantaneously lodge a knife into Subaru's shoulder upon believing that he was being manipulated. The two of them dislike each other, but only Subaru hates Todd while the the latter views the former as a target who must be killed due to his own internal and excessive fear. After encountering Todd on numerous occasions, Subaru firmly believes that he is scum comparable enough to the Sin Archbishops.

Echidna

Echidna was greatly interested in Subaru's Return by Death, as it allows him to collect all kinds of information that no other person could. She later invited him to her tea party in order to strike a conversation with him and later even offered Subaru her assistance in the form of a contract. However, Subaru rejected the offer after the other witches gave him hints that Echidna wasn't telling the full truth, noticing that she is actually using him to satisfy her endless greed. After the other Witches helped Subaru realize how Echidna's only goal was to use him as a lab rat, he decided to cut all ties with her. His opinion of her corresponds with his opinion of Roswaal, and it would even fog his views of Eridna, who shared the same name and behavior with her creator.

Petelgeuse Romanée-Conti

Petelgeuse and Subaru first crossed paths back in the early stages of Arc 3, during Subaru's 2nd failed loop. The Sin Archbishop ordered his followers to dispose of the earth dragon carrying Rem and Subaru and bring the boy to him, while killing the blue-haired maid. Upon waking up, Subaru was subjected to an unsettling scene of self-harming and madness, perpetrated by Sloth and his followers–a scene that would forever engrave itself in Subaru's mind. Soon after, Rem–mortally wounded but still alive–breached into the Witch Cult's hideout, however, Petelgeuse easily disposed of her with his Authority. The brutal action seeded deep roots of hate into Subaru's mind, and in the following loops, Subaru's hate for Petelgeuse would only continue to grow and escalate, due to witnessing the madman's campaign of terror through Arlam Village and Roswaal Manor, until, Petelgeuse became the person Subaru despised the most in the world, and was prepared to do anything in order to kill him. In the Arc's climax, Subaru would gather a subjugation force and tackle Sloth. It would, however, take two tries to defeat his body, but even utilising Julius' strength wasn't enough to defeat the Evil Spirit. It was only after a wild chase through the forest on a dragon carriage, that Subaru was able to defeat Petelgeuse by lighting him on fire and crushing him under the wheels of the carriage. Immediately following Petelgeuse's death, Subaru received the Witch Factor of Sloth.

During Subaru and Julius' fight with Petelgeuse, after Sloth possessed his body, Subaru felt he could understand and somewhat sympathise with the madman, though it didn't last for very long. In Arc 5, it is stated that Subaru felt absolutely no shread of remorse and hated his very existence from the moment the two first crossed paths a bit over a year before the events of Arc 5.

Furthermore, during the Subjugation against Greed in the latter half of Arc 5, Subaru deliberately referred to his Authority of Sloth as an Unseen Hand rather than Invisible Providence to crusch Regulus' pseudo-heart located inside Emilia's chest, likely in order to subconsciously prove Regulus wrong for berating Sloth's Authority for being too sluggish and weak – the very same Authority he considered to be miniscule in danger to him, proved to be his undoing.

Sirius Romanée-Conti

Subaru would first encounter the Sin Archbishop of Wrath at the very beginning of the Siege of Priestella. Having experienced her apologetic and grateful side while she was giving her speech, he at first believed her to be the closest one to normal when compared to the other Sin Archbishops. However, he would come to realize that she was just as demented as the others as she would proceed to kill him three times. That said, he would find her sudden attitude shift towards Emilia to be completely shocking, as even in spite of her dementedness, he had not seen her even remotely close to this in his previous loops.

Sirius does not seem to realize that Subaru is the one who ultimately ended her beloved Petelgeuse. In fact, after having witnessed his use of the Authority of Sloth, she would believe that the madman had continued existing in this brand new body, and she would shower him in her crazed love. Of course, Subaru would deny this, but it would still go in one ear and out the other.

Towards the end of the arc, Subaru would go to meet her in an attempt to glean any information he could out of her, which although minimal and not what he wanted to hear, he would pretty much succeed. Upon leaving, she would come to believe that Petelgeuse existed within Subaru, but he was overwhelmed by Subaru’s soul. As such, she would suggest to him to get rid of the three Sin Archbishops of Gluttony, and she would tell him to keep his body healthy for Sloth’s return.

Regulus Corneas

Subaru confronted him during his and Emilia's wedding in Priestella, which led to a battle that Reinhard joined in on and concluded with Regulus' death. Regulus and Subaru started off on a rather respectful note, but soon after exchanging a couple of words, they both started to strongly resent each other; Subaru's dislike stemmed from Regulus' abduction of Emilia while Regulus finds fault in Subaru's talkativeness and him disregarding his opinions which, which for him, meant that Subaru was belittling his rights, therefore he must be punished appropriately. Subaru regarded Regulus as an irredeemably evil person who had to be killed.

Capella Emerada Lugunica

Subaru would first meet Lust at City Hall in Priestella during the first counterattack. Though shocked by her initial draconic appearance, he would be the one to keep her attention. When he and Crusch entered the building, they attack the dragon that they see, but they are ambushed by the little girl they saved, who turned out to be Lust herself. After having seen what she had done to the people who were taken hostage in City Hall, he was absolutely disgusted by her methods, and he would be even more disgusted by her thoughts on what love really was. Ultimately, while he would lose to her, she would curse both himself and Crusch with the Dragon’s Blood Curse. Coming across the demi-beasts shortly after this, and even seeing the state that Crusch was left in, Subaru hatred for Lust rivaled that of the other Sin Archbishops.

Lye Batenkaitos

Even though Subaru didn't know Lye that well, he felt immense anger and hatred towards him for eating Rem's name and memories and placing her in a coma. Lye saw Subaru as his saviour as his Return by Death would allow him to experience tastes and memories like no other. 

Roy Alphard

Subaru and Roy's relationship is quite one-sided, as unlike his two siblings, the latter has not opted to target Subaru. However, upon their meeting in Priestella, Subaru directed immense rage towards Roy while mistakenly believing that he was the culprit behind the plundering of Rem's name and memories. When he was later defeated by Julius and Subaru was still reeling from losing Shaula, he wanted to direct all of his pent up rage and sorrow by killing Roy, although he was convinced otherwise by Anastasia since he was still necessary for releasing the remaining names and memories.

Rui Arneb

Subaru found Rui and her siblings' ways of stealing other people's existences to be abhorrent. He spared no sympathy for her and had no qualms with leaving her by herself in the Corridor of Memories.

Spica

Though the events of what happened to Rui in the Corridor of Memories remains unknown, shortly after that, Spica manifested in front of Subaru, and she alongside Rem were teleported to Vollachia together. Due to his connection with Rui, he and Spica got off to a bad start, Spica bearing the same appearance and Authority to the girl he knew. However, the personality she bore was vastly different to what he knew, causing him to be wary and afraid of her and her true intentions.

Over the course of Arc 7, Spica would continuously try to stick by Subaru’s side, attempting to protect him from harm from numerous characters, such as Rem, Todd, and the citizens of Chaosflame. However, the greatest example of her desire to protect Subaru came when she died protecting Subaru over and over again to Olbart Dunkelkenn. Because of this, not to mention seeing her bleed for him before this, Subaru’s views of her greatly changed.

Though they are separated for a while after this, when the two reunite, Subaru is glad to see that she is okay. During the retreat from Lupugana to Garkla, he finally confronted Spica about their relationship. Though he claimed he couldn’t forgive her actions, he still offered her his hand to start anew as an entirely different person to Rui Arneb, choosing to stick by her side if she wished to do so to prove to the world that she has changed. With their talks concluded, Subaru gave her a new name - Spica - so as to mark the start of her new life.

Sphinx

The two first encountered each other on the coupled dragon carriage, where he would stop “Valga Cromwell’s stratagem” from killing everyone on board. Sphinx would recognize Subaru as one of the largest threats to the Great Disaster after this.

Later, they would encounter each other again in Lupugana, Sphinx believing that the “foreign entity” may have been throwing off her plan. When they came face to face, Subaru would claim that he is her natural enemy, and Subaru’s group would engage in combat with her, ultimately winning after managing to outsmart her.
