Yamada-kun and the seven witches

the long version

"Yamada and the members of teh Supernatural Studies Club have been tasked with keeping problem-child Noa Takigawa and her lackeys in line. However, Noa is no ordinary student--she's a witch-- and it's up to Yamada to figure out her power. Yamada will use his brawn and (not so) clever tactics to discover Noa's power and end her hell-raising, but with her unconventional ability and devoted followers, it won't be easy! Can Yamada stop Noa before she causes more chaos at Suzaku High?" --
