Baban Baban Ban Vampire

A bathhouse employee appears to be an ordinary worker but is actually a 450-year-old vampire named Ranmaru Mori. The bathhouse's young heir, Rihito Tatsuno, is a fifteen-year-old virgin who is beginning to develop feelings for a girl at school. Concerned about Rihito's impending loss of innocence, Ranmaru devises a scheme to stop this from happening. His goal is to redirect Rihito's affections toward himself, hoping to eventually obtain the pure blood of an eighteen-year-old virgin.
