1-nen 5-kumi Ikimono Gakari

Eru Yamada is a 15-year-old student who belongs to her school's biology club, nicknamed the 'Ikimono Gakari' because she will take care of almost any living creature. Her ordinary school life changes when new member Ichiro Tanaka turns out to be a vampire. The club's adviser is a werewolf, and more supernatural boys—including an invisible man and a zombie—keep appearing around her. The comedy gradually develops into a supernatural romance as Eru and Ichiro become increasingly important to each other while the strange creatures around them keep turning school life into chaos.
