Anna is a little vampire girl who loves cute little animals. Whenever she sees an animal she likes, she is tempted to suck its blood and make it into her familiar making it grow wings. Because of her strange passion for cute things, her room is full of cuddly animals with black wings, and she even throws out her coffin because it isn't cute. Her cat familiar, Noel, always complains about her strange behavior. One day, Anna is on her way to see the fireworks at a town when she sees a poster for an Animal Circus full of wonderful exotic animals. Can Anna resist this temptation or will she end up creating her own little animal circus?
