Uruma Shun/Relationships

Kakeru Uruma
Kakeru is Uruma's younger brother. As children, they were as close as brothers could be, but despite this, Uruma never wanted Kakeru to know the troubles he was having with his classmates.

Even after the accident, Uruma did not stop being close with Kakeru. He would visit him at the hospital very often. Even talking with him about what's going on and what he's going to do. It's evident from the beginning that Uruma has a strong loving bond with his brother.

Shun Uruma Sr.
Shun Sr. is Uruma's grandfather. Uruma's first encounter with his that we see in the story is when he runs into him in the forest, after fleeing from the scene of the killed stray cat. After that, Shun Sr. brings him back home. Uruma's mother is seen to be very exasperated about his presence and warns Shun Jr. to stay away from his grandfather.

After his seemingly accidental parent's death, Uruma was invited by distant relatives to live with them, but declines the offers to instead stay with his grandfather, telling them that 'he does have a place to stay.' His grandfather welcomed him into his home.

Uruma goes out to his warehouse to get something for his grandfather. He notices a big picture of unusual military personnel hung up on the wall and some guns. He picks up one of the guns and is flushed with multiple emotions of vengeance. His grandfather comes in after him and tells Uruma to give the gun to him. Uruma refuses to let go of the weapon, he then told his grandfather of the true nature of his parents death, and cries out that nobody can take his revenge from him.

His grandfather then explains that he was apart of the infamous Kitayama Corps, where he was taught to efficiently kill and was trained in martial arts. He told Uruma that if he wanted to enact true revenge, he would teach him how to do it correcly. Uruma agrees and for the next 4 years, he used all the knowledge he had to train Uruma.

Besides being trained he seems to genuinely love his grandfather and regularly helps around the house.

Kyou Shigoku
Kyou is the main perpetrator of Uruma 's abuse, using Uruma as a "test subject" to see how far a human could be cornered before committing suicide, tormenting him daily. He’s shown to be the mastermind behind Uruma's parents' death. Uruma seems to hate Kyou the most and shows to have a burning hatred for him. Uruma describes him to be pure evil.

Kuga Daichi
Kuga is a pawn of Kyou but majorly just does what he wants he is shown to constantly beat Uruma mercilessly and seemed to enjoy it, however, he seemed to tone it down a little since they grew up, mainly because he has other victims. That, has been unfortunately averted as Kuga was willing to beat Uruma up when the latter challenged the former to a judo match.

Azuma Chizuru
Uruma's first interaction with Azuma is at school, when she noticed that he was being bullied. She tries to offer him help but Uruma assures her firmly that he doesn't need or want help. Azuma found it puzzling that he didn't any want help with his issues.

While Azuma was walking home from school, she was attacked by a pervert who was attempting to rape her. Just as the pervert ripped of her clothes and help a knife to her face, he gets a kick to the face by someone, which is revealed to be Uruma. He continues to fight the pervert and knocks him out cold. All the while, Azuma was watching the whole ordeal wrap out in front of her is surprised with Uruma's agile movements and fast action, this is where her attraction to Uruma might have started. Uruma reassures her that he will turn him in to the police. Azuma goes home, and when she is out of sight, Uruma he stabs the pervert, causing his death, and proving to himself that

The next day, Azuma gives him a cute key chain as thanks for saving her. This confuses Uruma but he accepts the gift anyway.

Later in the story, after Uruma defeats Ganno, Azuma confesses her attraction to Uruma very quickly. They then share a kiss (seemingly Uruma's first) which scares Uruma and he pushes her back away from him. These actions leave Uruma totally mixed up in different emotions, as his whole world was just about killing his targets.

Kaname Shirakawa
Uruma interacts with Kaname for the first time at school by being casted to be the Romeo, while Kaname was casted as Juliet for the school play. While Uruma was bewildered by the new attention he was getting, Kaname was blushing at the very thought of practicing the play. It is revealed that Uruma and Kaname actually first interacted in middle school, after Shun helped her after he saw her being bullied by the 5 antagonists of the story, which caused the antagonists to change their focus from Kaname to Shun. She claims that Shun was her light and he was her first love because he saved her from the bullies. After her rape at the hands of Madoka Hiro, he throws up seeing what happened, blaming himself for what happened to her. After this, he decides to get revenge not only for himself, but also for her. He assures her she will be fine and gives her moral support, claiming that no one will know about her scars and tells her to live on. Later on, after Uruma killed Kuga and became isolated, Kaname approached him and dragged him to an amusement park where the two rode all the rides. Part of it was to thank Uruma for what he did for her and having to carry the burden. Another part was wanting to forget the trauma that Madoka Hiro placed on her, leading her to ask him to have sex with her.

Jun Shirakawa
Jun is Kaname's older brother and an upperclassman of Uruma. He is fairly relaxed around Uruma while Uruma is a nervous wreck around him. This is mostly due to Kaname's nature. Jun explains to Uruma that Kaname has an attraction to him. He tells Uruma to 'take care of Kaname for him.' He adds on a threat that if he doesn't protect and care for her; he 'doesn't know what'll happen.' Nothing seems to have come of this threat. However, ever since the incident in which Kaname was assaulted by Hiro Madoka, Jun ended up holding a grudge towards Uruma as his sister is severely traumatised (whether this is due to his lust towards his sister or his desperation to help her is left ambiguous).
