• Personality : Intelligent, manipulative, sadistic, and chaotic. He says things like, "There's no real need to have a reason for doing things."
  Plot twist : He's the illegitimate son of the former CCG president, a secret member of the "V" organization, the Clowns, and even the Ghoul Restaurant. Basically, he was infiltrated everywhere.

There's also the case of Junko Furuta , which is a real and very serious case that happened in Japan in the 80s. But judging by how you wrote "I forgot about him," I bet you're referring to Tokyo Ghoul. c150
