Because of her last name Kumada (bear + rice paddy) and her appearance, Misas high school classmates call her Pooh disparagingly. She obviously has no friends and can only let down her guard around her pet parrot and the goldfish in the science room at school. But then she finds herself quickly becoming best friends with Izumi, a cute and popular classmate. Although somewhat puzzled by Izumis interest in her, Misa is excited about having a friend for the first time ever. But Izumis initial angelic demeanor gradually transforms into a demonic one.
