Yuusuke Asahina (朝日奈 侑介, Asahina Yūsuke) is the eleventh son of the Asahina family.
Yuusuke has messy, short red hair with two braids and dark red eyes. He's usually seen wearing a school uniform, but can also be found in athletic attire.
In Season 2 his hair is now in a low ponytail instead of braids. He now wears a white t-shirt and dark red jacket with white, purple, and gray trim. He then has gray trousers, a white belt, and black belt. One more thing is his necklace with a lock on it.
Even though he looks and behaves like a wild Yankee, Yuusuke has a really strong sense of justice. He hates everything twisted, often getting into a fight with delinquents to defend what’s right.
They are classmates. He had a crush on her before knowing that she was going to join the family. He has difficulties accepting Ema into the family due to his feelings and becomes conflicted with even the most trivial of things such as eating the cake she made for Subaru's birthday. When he got accepted in the same university as Ema will enter, he got so happy saying that he will not lose to any of his brothers. In the end of the novels though, Yusuuke cried a lot because Ema didn't chose him, but still wished a happy life for her and Subaru.
They are not on good terms. They always fight each other because of Fuuto's cheeky personality also not respecting Yuusuke.
