Makoto Satomi is a True Ancestor of the Vampire Clan, but a picky one at that. He's been in this world for a long time, yet he still hasn't awakened his abilities by drinking blood. A chance encounter during a heroic rescue—a pink-haired girl with headphones around her neck—unexpectedly triggers his vampiric urges. From that day on, Makoto's life becomes incredibly vibrant, and he embarks on the path to becoming a True Ancestor. The Five Sisters help him unlock his ability to differentiate, the Thunder Priestess helps him control lightning-powered familiars, and the Ice Sculpture Heiress awakens his icy powers… Makoto's power grows stronger, and the number of girls around him increases.
