Summary
You serves as a kleptomaniac and informant for Assistant Warden Tamaki, having been hired to keep an eye on Ganta in exchange for substantial Cast Points. While he maintains a facade of friendliness and politeness, his true nature is ruthless, scheming, and somewhat paranoid, a result of his role as a spy for the prison administration. You is an unusual case among the inmate population, as he deliberately got himself captured and sent to Deadman Wonderland with the specific goal of locating his sister, Minatsuki, and purchasing her freedom using the Cast Points accumulated from his work for Tamaki. He is deeply devoted to her, to the point where others often suspect he suffers from a sister complex, a perception that greatly disgusts Minatsuki. Despite this initial friction, the two siblings eventually manage to reestablish a strained relationship.
