Gakuto Mikumo's Manga List

Kojou Akatsuki lives on the artificial island of Itogami, and he has a secret: He's the "Fourth Primogenitor," the most powerful vampire in the world. He's carefully kept this dark knowledge from his family and friends, but one day, a beautiful girl named Yukina Himeragi appears before him and tells him that she knows who he really is--and that she's been sent to...kill him?!

Four years ago, a dragon filled the sky, the nation of Japan fell, and Japanese people around the world were wiped out. Yahiro, a survivor of the tragic event, works as a salvager who obtains Japanese artwork and artifacts for foreign buyers. Not many are willing or able to brave the ruins, which are crawling with monstrous beasts called Moujuu. But Yahiro's the best man for the task. After all, thanks to his regenerative abilities, he can't really die. He's approached about a job to search for the Kushinada, which is capable of controlling the Moujuu, but it will require delving into the most dangerous parts of the city. This is the story of a dragon girl and a dragon slayer.

He never asked for this power.
Kojou Akatsuki used to be an ordinary high school boy--but that wasbefore he became the Fourth Primogenitor, the most powerful vampire of all time. Worse--he doesn't even remember how it happened. Middle schooler Yukina Himeragi, meanwhile, is the Attack Mage sent to observe him--and to stop him if he gets out of control. But was it really a good idea to send a cute girl to observe a massively powerful vampire boy whose abilities activate whenever he gets aroused? And on an artificial island populated with all manner of demonic individuals, each with their own designs on the Fourth Primogenitor--?!
