Description
The Fourth Primogenitor is the world's strongest vampire that should only exist in legends, but he has emerged in Japan with twelve familiars to spread chaos. For the observation and obliteration of this fourth primogenitor, the government and Lion King Organization decided to dispatch an attack mage as a Sword Shaman to observe his every move. For some reason [A/N: Which tbh, is plot armor BS], the one chose for the observation was an apprentice Sword Shaman, Yukina Himeragi, who is just an academy girl! Wielding the strongest anti-demon spirit spear, Yukina arrived at Demon District, Monster City of Itogami City, to find the fourth primogenitor. Surprisingly, the primogenitor is an academy student, Y/N L/N, who can't even remember how he became a vampire! However, he seems to be the most peculiar, hiding a mysterious past, he seems to be more dangerous than the previous primogenitor. ---- Rated M for Mature. Mature Scenes, Ecchi, Language and lots and lots of Lemons!
