he's a good guy, he's kind and caring, lovable and such. he's usually shy and/ lazy around people. but some things can set him off, some much easier than others, simply calling him a name would make him break down and scream, cry, or try to kill you. when he's all alone, he's pretty sad and angry.
um.. his clothes, he doesn't use anything but his hands and the recourses around him at the time.
His life was pretty okay until he was about 5. His father went insane and killed his mother after he found out that she had been cheating on him. Then his father took care of him (no, there were no cops or anything in this place) and got interested in the shrine that harbored a demon, he decided to turn it into a tourist site and then he unleashed it's power and died around the time Setai came to give him his lunch. His father was covered in the energy from the god, which was absorbed into Setai and the demon had been sucked into him. The village Setai lived in was overrun by demons so he just became another outcast that everyone hated. He met someone when he was grieving over the loss of his mother as he did most days and she had helped him scare the crap out of the bullies. They have been friends ever since.
