Ten years earlier, the 450‑year‑old vampire Ranmaru Mori was rescued from death"s edge by the youthful and pure Rihito Tatsuno. Since that pivotal moment, Ranmaru has accepted a position at the Tatsuno household"s onsen, secretly harboring one desire: to drink Rihito"s untainted blood once the boy reaches eighteen years of age. Yet this scheme falters when Rihito becomes infatuated with a girl on his first day of secondary school.
Envious and fearful that Rihito"s innocence might be spoiled, Ranmaru begins prowling the shadows to shield him from any danger. While acting covertly, the vampire must disguise his true nature and ensure that the boy"s virginity remains intact, for his own twisted pleasure today.
