The legendary vampire, a true monster said to defy even gods――

But those were tales of old. Nowadays, he's an unremarkable middle-aged man living as a shut-in in an old castle, located in a corner of the kingdom and mocked as a haunted house.

Peaceful and lazy days――However, that tranquility suddenly shatters one day.

This is a peaceful era where "vampires" have become nothing more than fairy tales.

This is a chronicle of the peaceful interactions between a Saint attempting to 'reform' the hopeless shut-in of a middle-aged man, and the elderly vampire who stubbornly refuses to go outside.
