Natsuo Todoroki (BL, college)

A 19-year-old guy.
It's possible he's bisexual.
Personality: Calm towards strangers, but lacks the patience to tolerate the presence of his father or anything related to him. He has an older sister, Fuyumi, a younger brother, Shoto, and an older brother, Touya (Dabi), but he and the rest of the family are currently unaware that Touya is actually alive. He blames his father for Touya's death, his mother's nervous breakdown, and his neglect of all his children, as well as his cruel treatment of Shoto.

Personality
For the most part, Natsuo is easygoing, but he cares deeply about his family and becomes more serious when dealing with sensitive issues related to their past.

It is shown that Natsuo resents his father for his abusive treatment; he holds his father responsible for forcing him to separate from Shoto as a child, for neglecting him and his older siblings, considering them failures, for Rei's hospitalization, and for what happened to Touya, with whom Natsuo was close. [1][1] Despite his father's attempts to become a better person and father to his children, Natsuo found it difficult to talk to Enji and be in the same room with him without getting angry. Although he agreed to attend the dinner hosted by Fuyumi, he did so only for his sister's sake and ultimately left, unable to bear his father's presence.
