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!?

Kojou was a normal 16-year-old high school student 3 months prior to the beginning of the story, until becoming the 4th progenitor after his predecessor, Avrora Florestina inserted her spirit into his body as the result of a wish. He claims to remember nothing of the incident. When aroused, his blood lust takes over and the only way to satisfy it is to drink his own blood, usually from the nosebleeds he experiences. As a vampire, Kojou possesses superhuman strength, speed, reflexes, and durability, but has far greater power than that of a normal vampire due to his status as a progenitor. He has also inherited Avrora’s twelve familiars. Due to never having drank human blood, Kojou at first has no control over his powerful familiars, but after drinking an individual’s blood, one familiar will acknowledge him as its master. By drinking the blood of others who have familiars, he is able to gain control over their familiar. By volume 9, he is able to control 6 of the familiars. Kojou is also lacking the 6th, 10th and 12th familiars, the 12th being in Nagisa and the 6th and 10th still have their human bodies. In Strike the Blood EX, he has two daughters (in the future); Reina from Yukina, and Moegi from Asagi.
A 14-year-old middle-school Sword Shaman from the Lion-King organization, Yukina was sent to observe the 4th progenitor and was told to kill him if he becomes a threat. At first, Kojou tries to trick her into thinking he’s the wrong person, but his strength is revealed when he intervenes in a fight between her and another vampire. She is constantly following him everywhere he goes and as a result has become very close to him, even allowing him to suck her blood in order for him to gain control over his familiars. Unbeknownst to her, she was actually sent for this very purpose; with the organization intending for her to be his first blood partner, and even his mate. Like many others, she was supposedly sold to the Lion-King organization by her parents. By the end of the first arc, she seems to have developed feelings for Kojō. In one episode she told him to stay by her side forever. In Strike the Blood EX, she is presumed to be married with Kojou and they have a daughter named Reina.
A 16-year-old War Dancer (specializing in hexes and assassinations) from the Lion-King and Yukina’s former roommate. She is highly over-protective towards Yukina and dislikes all men – Yukina tells Kojou that she used to screen her calls because she couldn’t stand having a male voice talk to her. At first, she despises Kojou for being close to Yukina, but after she offers her blood to him (to awaken his second familiar) Sayaka begins to develop feelings for him. Like Yukina, Lion-King actually arranged the meeting between Sayaka and Kojou, intending for her to become his blood partner as well.
Natsuki is Kojō’s English teacher and an attack mage. Despite claiming to be 26 years old, she has the appearance of a grade school girl. She is usually seen wearing a gothic lolita dress. She is one of the few people who knows that Kojō is the 4th progenitor. She is a high ranking mage and is called “The Witch of the Void”. It is later revealed that she is actually the guard of the magical prison barrier that houses the most dangerous supernatural criminals; her actual body is sealed deep within the prison, while the teacher and mage everyone interacts with is actually an illusion. Kojō, Aiba, and Yaze usually call her “Natsuki-chan” despite her repeated demands to address her as “sensei.”
