OVA
Description
Kojou Akatsuki began as an ordinary human until a critical incident altered his existence. During a terrorist attack at Fairy's Coffin, he shielded his younger sister Nagisa Akatsuki and Avrora Florestina, sustaining near-fatal injuries. In response, Avrora, the Twelfth Kaleid Blood, converted him into her blood servant—a pseudo-vampire. She then commanded him to destroy her and "Root," designating him as her successor and triggering his ascension as the Fourth Primogenitor. This transformation erased his memories of Avrora and the events, though fragments surfaced during battles, such as against the Third Primogenitor Giada impersonating Avrora. A ritual performed by Yukina Himeragi, which he underwent alongside Asagi Aiba, fully restored these memories.
Before becoming a vampire, Kojou displayed athletic prowess as a middle school basketball player, leading his team to a city championship and earning MVP honors. His dominance inadvertently caused teammates to become overly reliant on him. An injury during a pivotal game exposed this dependency, leading to his withdrawal from the sport and contributing to his aversion to standing out or shouldering others' expectations.
Physically, Kojou appears as a 16-year-old with dark silver-blue hair and blue eyes that shift crimson during emotional arousal, anger, or vampiric power activation. Avoiding sunlight results in fair skin. He typically wears Saikai Academy's uniform: a white shirt, black pants, blue undershirt, and white hoodie, and possesses a well-toned, muscular physique.
Personality-wise, Kojou exhibits kindness, empathy, and a carefree demeanor, often assisting others selflessly. Despite his relaxed exterior, he possesses sharp intellect and tactical acumen that emerge during crises. A quick temper surfaces when mocked or when loved ones are threatened, revealing a formidable and fiercely protective side. His willpower and charisma attract allies and convert former enemies. A defining trait is his profound devotion to Nagisa, rendering him oblivious to romantic advances from others, including Yukina Himeragi, Asagi Aiba, and Yuuma Tokoyogi.
As the Fourth Primogenitor, Kojou commands twelve Beast Vassals (Kenjuu), manifestations of his vampiric power. Early struggles with control stemmed from his refusal to consume human blood, causing the familiars to rebel. Mastery required ingesting blood, initially from human companions via magical rings and later directly from Avrora and Yukina. His known Beast Vassals include:
- **1st: Mesarthim-Adamas**, manipulating diamonds for offense and defense.
- **3rd: Al-Meissa Mercury**, devouring space/dimensions.
- **5th: Regulus Aurum**, generating and controlling electromagnetic energy.
- **7th: Kiffa-Ater**, manipulating gravity via a colossal sword.
- **11th: Sadalmelik-Albus**, reverting phenomena to nothingness, enabling recovery from fatal injuries.
His vampiric physiology grants superhuman strength, speed, regeneration, immortality, enhanced senses, mist transformation, and "Cleansing"—a reality-warping ability altering physics and magic.
Kojou's development centers on accepting his role. Initially reluctant and struggling with power instability, he gradually harnesses his abilities to protect Itogami Island. Key milestones include:
- Forming contracts with blood companions like Yukina and Asagi to stabilize his familiars.
- Drinking Astarte's blood to command her familiar, Rhododactylos, saving her life.
- Learning shikigami summoning.
- Developing precognition during temporal loops on Onrai Island, foreseeing ally deaths.
His relationships evolve significantly, particularly with Yukina, his primary observer and eventual partner. Future timelines confirm romantic outcomes with multiple characters, resulting in children like Reina and Moegi Akatsuki.
In the OVA *Kieta Seisō-hen* (Disappearing Holy Lance Arc), an original storyline, Kojou confronts new supernatural threats tied to the Holy Lance's vanishing. This arc tests his adaptability and leadership as he coordinates allies to resolve the crisis.
Kojou's legacy expands as the future ruler of Reich·Der·Morgenrot (Akatsuki Empire/Dawn Empire), where he balances governance with protecting his extended family and allies.
