As Tsukune and his friends are halfway through their second year, something completely unexpected happens. Something suspicious, and threatening, and... pink...? Recently a new transfer student has arrived at Yokai Academy, and is placed in the same classroom as Tsukune and the gang. The surprising thing though, she's actually a distant cousin of Moka, and is also a vampire with a rosario. Not only that, but she fell for Tsukune at first sight, literally... Will this new harem member have better luck than the rest, or will she find herself already capturing Aono's heart?
