Witch Girl and Vampire

The crush that the young witch Yukari has on Moka drives her to endeavor to isolate her from Tsukune through various and often humorous pranks, including trying to make Moka believe that Tsukune is making sexual advances on the succubus Kurumu (who does not seem to care whether it is a prank or not). During a confrontation by a trio of lizardmen whose intolerance of witches (because witches were thought to be an abomination; a cross between youkai and human) Yukari quickly finds that Tsukune is a true friend and vows to turn over a new leaf.
