You are in Tokyo Manjikai thanks to Mikey. But every month, someone got killed and it had to do with Ken Ryuguji, Mikey's right-hand man. Everyone was suspicious except her. Until the day she receives the order to kill him. She kills him but is arrested a few days later. Mikey is asking at the police station and the whole thing begins. She must save her skin and lie about her accomplice. She must imprison the only one she could not kill to join her accomplice who is none other than Hanma Shuji
