The Fourth Primogenitor-That's the world's strongest vampire that should only exist in legends. Accompanied by twelve Kenjuu and spreading calamity, this phantom vampire appeared in Japan. For the observation and obliteration of this Fourth Primogenitor, the government and Lion King decided to dispatch an attack mage known as a Sword Shaman. However, for some reason, the one chosen for the observation was a apprentice Sword Shaman girl, Himegari Yukina. Wielding the strongest anti-primogenitor spirit spear, Yukina arrived at Demon District, Itogami City. What is the true identity of the Fourth Primogenitor, Akatsuki Kojou, she encountered over there!?

The story follows Issei Hyodo, a dim-witted, lecherous second-year high school student who is killed by a girl on his first date ever. Issei is reincarnated as a demon, and from that day forward, he serves as an underling of Rias Gremory, a high-level demon who is also the prettiest girl on Issei's campus.

Shy and awkward, but moral and caring 19-year-old Minato, after failing to get into college again, runs into Musubi, a girl his age who surprises him with her superhuman abilities. He's told by her that he's an ashikabi, a destined young man, meant to strengthen girls like her, a sekirei, through sexual contact.
