Character Arc

Rihito Tatsuno is the wholesome high-schooler whose family runs the Koi-no-Yu bathhouse, and the unwitting target of Ranmaru's long game. Cheerful, earnest, and a little naive, he has no idea that the friendly new part-timer is actually a centuries-old vampire counting down to his eighteenth birthday.

Much of the comedy comes from Rihito simply trying to live a normal teenage life, with crushes and classmates and after-school plans, while Ranmaru hovers in the background sabotaging anything that might threaten his purity. Rihito reads the vampire's meddling as overbearing big-brother energy, never guessing the real motive behind it.

As the season goes on, the bond between the oblivious boy and his self-appointed guardian becomes genuinely affectionate. Rihito's good-natured sincerity is what slowly softens Ranmaru, turning a hunter-and-prey setup into a warm odd-couple friendship.
