This is Masahiro, one of the two main characters of
Grassblades! Masahiro does not like you. Masahiro does not like your friends. In fact, Masahiro does not like ANYONE, and would very much like to be left alone now, please, so he can get where he's going. However, beneath that grumpiest of surfaces, he can't help but be a little bit decent - a little, but just enough to, you know, not leave bloodstained little girls to their fates in the woods. Masahiro does not actually want to fight you, but he will if you push him.
Has vaguely defined powers, including eyes that sometimes light up blue, and a tendency to lash out with a similarly blue-glowing sword. Is also missing his left hand from the wrist down, but keeps that hidden with his sleeve.
