A scumbag trying to use Guest's name to do all sorts of depraved things. He tries to mimic the clothing and speech patterns, but since he's just a fat guy, he's immediately found out. His motive (?) is that he wanted to build a harem surrounded by students, but since Guest was in the way, he thought he could pull it off by just pretending to be Guest.

Students from all the schools existing in Kivotos.
