Izaya Orihara | Durarara!!

A young man who sells information for his own enjoyment and the main antagonist. He claims to love the entire human race except for Shizuo Heiwajima, and exhibits said love by putting humans in often miserable conditions and observing their reactions.
He is behind the most relevant events of the series. He knows the identities behind each of the leaders of the three main forces in Ikebukuro.One of his main goals is to create a war in Ikebukuro that will "wake up" Celty's sleeping head.His name comes from a combination of the biblical Isaiah and Japanese for "the one who looks over the crowd."He is usually seen pretending to be female online and talks in a feminine manner in the chatroom. His screennames are "Kanra" and "Chrome". Well done by GhostKiller.
