Chuuya is a Port Mafia executive. One day his ex partner in crime Dazai recruits Chuuya to help him with a jailbreak from Mersualt prison in France. The jailbreak is like a murder game and Chuuya nearly drowns while Dazai ends up falling down an elevator shaft. While trying to escape Chuuya gets bitten by Bram, a vampire, and Chuuya turns into a vampire. While as a vampire he has no control over what he does or says and Fyodor Dostoevsky has full control over him instead.
