Rosario to Vampire Season II

Synopsis:

Tsukune, Moka, Yukari and the others are back, and ready for more adventures at the Youkai Academy. After hunting down a doppelganger, exposing a serial prankster and even dealing with the hassle of joining school clubs, things take a serious turn for the worse: an evil human organization threatens the sanctity of the monster haven, using an innocent girl in the process! With Moka's vampire blood now running through Tsukune's veins and a limiter keeping him from turning into a ghoul, plenty of Moka's sisters now in the picture and a conspiracy around the corner, this year at Youkai Academy will prove to be the most dangerous yet!
