In Season 2 his hair has seemed to grow longer and shaggier. He wears now a blue jacket with 5 buttons, gray trousers and white and blue sneakers.
Subaru has been dedicating his life to basketball ever since he was small. 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 was shy, he is the first person to confess to 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 cries, 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. At the end of the novels, 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 lived together in tokyo.
Natsume was the one who originally influenced the path towards a professional sports career upon Subaru.
