Shishito Madoka

Shishito Madoka is a Complete Forgery in the First Unit. Later, in chater 36, it is discovered he intended to personally torture and kill Ganta. Because Madoka severly bullied as a child and lost his father to the earthquake, he grew into a psychopath who enjoyed being "unhappy", so he made others "unhappy" as well. He tortures Ganta by making him feel the sensation of being rammed into the wall. Then he crucifies Ganta. When Madoka discovered Shiro's life meant more to Ganta then his own, he decides to torture Shiro with the iron maiden. Fortunately Ganta and Shiro are able to defeat him in a combined attack.
