Zombieya Reiko

Terror has struck the sleepy little town of Shiraike. A serial killer stalks the streets murdering innocent girls. Twenty-nine grisly murders have been committed, with no clues to catch the killer. That is, until the town receives a strange visitor: a beautiful young woman who can raise the dead. She is Reiko the Zombie Shop, necromancer for hire. For a price, she'll wake your dead, if only to find a clue to their demise, but she's not responsible for what the dead will say or do once they awaken!
