Zodiac sign: Taurus
Kojou was just a regular high school student until three months ago, when the original 4th Primogenitor transferred her spirit into him—supposedly to fulfill some kind of wish or deal they'd made. The exact details are fuzzy; he can barely remember what actually went down.
His new vampire side doesn't always play nice. Sometimes his urges flare up, his eyes start turning red, and he gets nosebleeds and coughing fits. Yukina has pointed out that it shouldn't be possible for a human to randomly become a Primogenitor like this, which is part of what makes his situation so weird.
Being a Primogenitor comes with serious perks. He's got the standard vampire package—superhuman strength, speed, reflexes, and durability—but cranked up way higher than your average vampire because of his status. He also inherited Avrora's twelve familiars, which gives him even more power to work with.
