Babanba Banban Vampire - S01

Ten years ago, Rihito Tatsuno-a kind-hearted boy-saved the life of 450-year-old vampire Ranmaru Mori. Since then, Ranmaru has worked at the Tatsuno family’s bathhouse, hiding his true motive: he’s waiting to taste Rihito’s virgin blood once he turns 18. But Ranmaru’s plans are thrown into chaos when Rihito starts high school and falls for a girl. Fearing the loss of Rihito’s purity, Ranmaru grows possessive, secretly watching over him to shield him from danger. Now the vampire must balance his hidden nature with his mission-keeping Rihito untouched until the day he can finally claim his prize.
