Brothers Conflict Wiki

Subaru Asahina (朝日奈 昴, Asahina Subaru) is the ninth brother in the Asahina family and one of the main characters of the series.


Subaru has short, messy grey hair and grey eyes. He is often seen wearing a sleeveless shirt with a hood jacket with the name of his university at the back along with track pants.


Subaru has been dedicating his life to basketball ever since he was young. Because of his stoic and upright personality, combined with the fact that he’s absolutely not interested in anything other than sports, Subaru doesn't have any experience with women. He is very shy around Ema and always stutters when he speaks to her. Although he is shy, he is the first person to confess his feelings to Ema.

Before Ema entered the family, Subaru let his passion for basketball captivate his life so completely he couldn't think about much else. He didn't interact with women, and having Ema in the house made him feel awkward. However, he was surprised at how perceptive and kind she was, even though she barely knew him. He was shocked and touched that she noticed how hard he worked at basketball, training every day and doing road work as well. Her kind and giving nature made him feel attracted to her, and for once in a long time got him to care for something more than just basketball.

However, in the beginning, he didn’t know how to handle his new feelings for her, which resulted in him doing something he would come to deeply regret. On the night of his twentieth birthday party, while drinking with some of his older brothers, he was embarrassed by Tsubaki’s taunting and ended up saying that he finds Ema annoying. As he was leaving the living room he was shocked to see that Ema had overheard everything. Not long after, he went to her room to apologize for his outburst; however, whether due to his emotions or the alcohol, he wound up forcing a kiss on her. Ema would later chalk this up to an accident, but Subaru would experience so much guilt over his actions that his basketball skills suffered. It was only after Ema made it clear that she didn’t blame him for anything that he was able to move on.

After this, Subaru became protective of Ema, and her mere presence gave him strength. He accepts his love for her, and wishes to keep her by his side forever, knowing that he can reach his full potential as long as he has her. He hates to see Ema upset, and feels ashamed whenever he lets his anger get the best of him, and as a result, punches Natsume in front of Ema. He wants to become a good man, so he can make her happy, and will never give up until she is his.


Hinata Ema[]

Subaru is often self conscious and awkward around Ema, and has been drawn to her upon their first meeting. They very often have awkward moments, and Ema blushes while she tries to come up with something to say. He is usually caught sneaking glances at her when no one is looking. Later on, when Subaru leaves the house and tells Ema to forget about everything that happened between them, in order to focus on basketball. She ends up crying, but awaits for his return. She also admits, she likes, and admires Subaru for his love for basketball. She even went to one of his games, and because of her being there, he was able to win the game, and do his best while on the court.

Only at the end of the novel, though, Ema is the one to confess to Subaru and they become a couple. In 13 bros. maniax it is shown they have a daughter named Chitose and they all live together in Tokyo.

However,only in the manga end he is shown patching things up with Natsume, before confessing that he truly did love Ema, but is willing to let her be with Natsume if that will make her happy.
