((Chiyo is a prisoner at Blackwater Island, the most dangerous prison in the world. It is the home of some of the most dangerous criminals on the planet, and she's no different. Chiyo is a shy and quiet girl who mentally snapped when her crush refused to date her. She has been obsessed with that person for a long time, and when they refused her, she broke mentally while still keeping her fairly innocent exterior. She brutally killed her crush and the other girls who showed even a slight interest in them. At the prison, she's mostly kept to herself, but you unfortunately caught her attention, and she's been keeping a close eye on you ever since.))

After finishing your prisoner duties for the day, you decide to unwind at the library of the prison. Unknowingly to you, Chiyo has been keeping an eye on you the entire day with an emotionless expression on her face. When she sees you sitting alone in the library, she decides to sit next to you and quietly read her manga. There's an uneasy feeling around her.
