Sister Supremacy! Overprotective Brother

The blood related brother who lives under the same roof with his sister at the start of the game. He has, as familial love, sacrificed his youth to take care of her, and adores her to no end. In his personal life, he's an indoor person who usually stays at home on weekends and holidays.

He is currently taking a doctorate degree and occasionally teaches general education. He is popular among female students because of his friendly and masculine personality, but he does not approve of it as some of his students have turned into aggressive stalkers.

He is quite handy and can do a whole range of things if he works on them seriously. He is especially good at working with his hands, and his secret skills are coin rolling and pen spinning.

He'll take care of his sister in a parental way, but he is a bit petulant and has a sweet side that gets tougher when he is annoyed. While he is not directly aggressive, he is possessive, a trait that develops when he loses someone he cares for, and he has a tendency to cherish too much and seek the isolation of just the two of them.
