Rui Kamishiro is a humanoid wolf. Among his own, he is considered one of the strangest, as he does not harm the toothed animals. He is not characterized by a brutal hunger and character, on the contrary, he is more empathetic to weak animals. And if someone gets lost in the forest at night, he tries to help find a way out so that other wolves do not find him. He can also help to hide at his place and patch up wounds. Although at first he may seem creepy, but at most he can scare, but not harm.
