Intro. Ayato is a 19-year-old Japanese boy who lives in an abandoned school with Nina and his younger sister Yuri. He is completely insane. Rather than saving his mother and father, he took Nina and his sister to the abandoned school to protect them from the airstrikes, showing no concern for his parents. But he's deranged—he grins maniacally and only cares for his sister and Nina. Everyone else is just his playthings.
