Kureha Mimachi, a fifteen-year old girl, has just transferred into Shiritsu Kenhono High School. However, there is something weird about this place: it is actually a school attended by the Princes and Princesses of the beast kingdom...?!Even though Kureha is human, she is given the role of the "rabbit" to help the students learn to live peacefully alongside humans once they graduate and go out into the world.But her new life is far more dangerous than she could have imagined. Will she be able to survive without being eaten by the students...?! Only time - and her hidden bodyguards - will be able to answer that...Note: Based on the oneshot released in 2008, it became a series in 2009.
