Kojou Akatsuki

**Kojou Akatsuki** (暁 古城, *Akatsuki Kojō*) is the male protagonist of the story. He is the older brother of Nagisa Akatsuki and the childhood friend of Yuuma Tokoyogi. Although he appears to be a normal high school student studying in Saikai Academy, he is actually the fourth primogenitor; the strongest vampire in existence, an immortal demon thought only to exist in legends. He became a vampire and the fourth progenitor only three months before the beginning of the story. For much of the story, he cannot remember how he became a vampire and gets an intense headache whenever he thinks about it too hard. His vampiric urges surface every time he is sexually aroused, his nose bleeds during these situations, and he can only stop his vampiric urges by drinking blood. At the beginning of the story, Yukina Himeragi is sent from the Lion King Organization to observe him and to eliminate him if he is deemed dangerous.

## Appearance

Kojou is 16 years old at the beginning of the story. He has dark silver-blue hair and blue eyes which turn red when he is either aroused or angered. He is usually seen wearing the Saikai Academy school uniform which consists of a white button up shirt and black pants. He also wears a blue under shirt and a white hoodie. Since he is a vampire and tends to avoid daylight, he has fair skin. He has well-toned muscles and a "well-endowed" body.

## Personality

Kojou is a kind, empathetic person, who goes out of his way to help others. He is also an intelligent, sly and carefree individual. When angered, Kojou becomes quite fearsome adversary. Kojou has indomitable willpower, supernaturally strong charisma which has attracted the attention of both admirers and allies, allowing him to even befriend his enemies. Kojou is shown to care and worry about his sister a lot. He is however generally oblivious to the romantic feelings that others have of him due to his strong siscon nature.

## Abilities

Despite being laid back, he has repeatedly shown to be extremely intelligent, clever and a quick learner, although these traits are not usually shown because he usually tends to charge without thinking, but he can be impressively logical, observational, deductive & tactical. These traits make him an excellent leader.

**Enhanced Vampiric Abilities:** He possesses supernatural strength, durability, agility, awareness, speed, senses, regeneration capabilities, pheromones, endurance and immortality. Being the Fourth Primogenitor, his incredible powers are far above that of most vampires. Kojou is absolutely immortal meaning he doesn't age or get sick and he will rapidly recover from any damage he receives, even from decaptation or complete incineration.

**Familiar Summoning:** Kojou has twelve familiars which are manifestations of his vampire's powers. Initially, these familiars would not fully obey Kojou and would often go on rampage. This is due to the fact that he refuses to drink human blood and thus, they would not acknowledge him as their master. However, he is able to control his familiars and summon them properly once he drinks blood. It is revealed that Kojou is still lacking three familiars inside him, one of them is the 12th that lies inside Nagisa while the 6th and 10th still have their Kaleid Blood bodies. They are currently in Oceanus Grave II under the custody of Dimitrie. Every time Kojou releases new familiar, he says the following chant:

I, Akatsuki Kojou, successor to the blood of "Kaleid Blood", now release your constraints. Come ....(number and name of familiar)
