Yukina Himeragi is the female protagonist of the series. She is an attack mage, or in the Lion King Organization, a Sword Shaman, who is sent by the Lion King Organization to observe the Fourth Primogenitor, Kojou Akatsuki. As she's appointed to observe him, she became a middle-school student studying in Saikai Academy who follows him everywhere and is also ordered to kill him if he becomes too powerful and insane to control himself. ~!She is also the first blood mate of Kojou, and thus being the first, her blood smell is always associated with Kojou's own smell, which has been pointed out many times by other characters who could smell blood, probably due to her blood interbreeding with Kojou's as she was the one who activated Kojou's first 'real' vampiric act. Also, unknown to her, she was intended and prepared by the Lion King Organization to be his lover.!~

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!?

La Folia's father, Lucas, had told her to decide who she wished to marry, so she declares that Kojou is her choice. Lucas refuses to accept this, but then La Folia's mother, Polifonia, invites Kojou and Yukina to a party so they can all talk in more detail. When they arrive at the party, they discover that Asagi, Yaze, Nagisa, and Sayaka have been invited as well, due to their connections with Kojou.

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--?!
