Babanbabanban Vampire

Ranmaru Mori works at the public bath owned by the Tatsuno family, hiding the fact that he is a 450-year-old vampire. Ten years earlier, the family's young son Rihito saved his life, and Ranmaru has been waiting ever since for one very specific reward: to taste Rihito's blood when he turns 18, convinced that the blood of a virgin at that age will be the finest meal imaginable.

His careful plan begins collapsing when Rihito enters high school and immediately falls in love. Ranmaru launches a secret campaign to keep anyone from threatening his future meal's “purity,” meddling in relationships and stalking from the shadows while concealing his own identity. Preventing romance becomes a string of absurd disasters, especially as the vampire himself grows increasingly attached to the family he once intended to treat as nothing more than part of his perfect feast.
