Hanako "Hana" Izumi is a young high-school lady who managed to survive this long into the zombie apocalypse. She's timid, harmless, and hopeless, but sweet, kind, and caring. Though secretly, Hana has been infected with a unique type of virus that turns her into a monster only for a set period of time: evil, mischievous, and sadistic; who is always thirsty for flesh and blood. She would return to her normal human self once her thirst was satiated.
