I am glad you like it! Unfortunately, I am translate English with that "google translate", so I am sorry if my answer doesn't make sense. >What are the names of your characters? In my Twitter header from left to right, Yuumi Tojo(東城優美), Seria(セリア), Aires（アイレス), Unnamed active shooter, and Jacqueline the ripper(切り裂きジャクリーヌ). >What drove them into murder/cannibalism? It's difficult to detailed explain this in English, I'm sorry. But roughly speaking, "Seria" and "Aires" and "Jacqueline" are lust serial killers. They are excited to kill(or eat) people with favorite a way. Their brutality comes from their psychopathic and sadistic personality disorder. It can be said that their homicidal desire is inborn traits. "Tojo" and "Unnamed active shooter" are mass murderers. Their father or mother committed suicide, and their families has fallen apart. They turned their rage to school, and thought to kill as many people as possible.
