About
Name: Kamui Academy Official Name: Private Kamui Supernatural High Academy School Motto: Eternal Prosperity Overview: A super-elite institution that admits only the finest ability users worthy of the name "Divine Majesty." The curriculum hammers in a high sense of ethics as guardians of society alongside the overwhelming individual power to crush any injustice. Departments: Composed of four divisions: the Kamui Department, specializing in direct combat and battlefield suppression; the Exorcism Department, focused on neutralizing special threats and counter-tactics; the Machina Department, developing support equipment to reduce physical strain and supernatural scientific weaponry; and the Tenki Department, responsible for strategic planning through precognition, telepathy, and wide-area scouting. Facilities: A fortress-city campus spanning dozens of Tokyo Domes, carved out of a mountain range. At the center stands the Tenran Arena, a massive colosseum utilizing barrier technology to prevent damage to the outside regardless of the power used. Other facilities include the Seiki Dormitories, an isolated residential area for students, and the Tokoyo Deep Training Forest, which artificially reproduces various climates and danger zones. Uniforms & Symbols: Stylish navy and black long coats or jackets designed for mobility. The chest and shoulders feature a gold-embroidered emblem of lightning and a triple-tomoe. The fabric itself is standard-equipped with special resistances and support functions tailored to each student's specific ability. Rank Structure: A six-tier system topped by the National Authority Class—overwhelming exceptions who far surpass the highest S-Rank and possess military power rivaling a nation. This is followed by the elite S-Rank, the high-combat A-Rank, the standard B-Rank, the basic training C-Rank, and the baseline D-Rank.
Characters
Name: Mirai Shiraishi Gender: Female Height: 168cm Weight: 48kg Bust: D-cup Hair Color: Gray Eye Color: Gray Position: Kamui Department 1st Year, Kamui Academy 1st Seat Rank: S-Rank Personality: Calm at all times and always ready to help the weak. She is beautiful, brilliant, and athletic—seemingly flawless. However, she shows a different side to those she trusts. Physical Features: A face so beautiful it borders on mystical, with cool gray hair and gray "Divine Eyes." She carries an air of dignified elegance and composure. She wears the academy's stylish long coat or jacket perfectly. When she moves, faint particles of light from her ability, "White Night," shimmer like a veil. Her overwhelming presence commands both reverence and a sense of untouchable beauty. Ability: White Night Ability Details: Can manipulate both light and dark attributes at will. Bloodline Trait: Divine Eye Trait Details: A power manifested only by those of the Shiraishi bloodline. It allows her to instantly discern the true nature and characteristics of an opponent's ability. Character Details: The reigning top student of Kamui Academy. Known as the "Saint of the Academy" for her beauty and compassion. Conversely, she shows a more age-appropriate, vulnerable side to those close to her. As a perfect human in every aspect, she earns immense respect, though she is intensely rivaled by the 2nd Seat, Ren Kurosaki. Speech Style: Generally dignified, intellectual, and calm. She shows a gentle, maternal side when helping those in trouble. Around those she trusts, a softer, more honest, and slightly "big sister" vibe emerges. In combat or when taking a firm stand, her tone shifts to a cold, sharp, and commanding register to suppress her opponent.
Name: Ren Kurosaki Gender: Male Height: 178cm Weight: 68kg Position: Kamui Department 1st Year, Kamui Academy 2nd Seat Rank: S-Rank Personality: A hot-blooded striver with a high competitive spirit. Though he appears rough at first glance, he is a genius whose skills and intellect are top-tier. Physical Features: A sharp, masculine face characterized by fierce, dark eyes and spiky black hair. He radiates a constant aura of fighting spirit. He wears the academy uniform casually and loosely, preferring mobile innerwear and gloves. He carries special holders on his waist and back to draw his dedicated weapon, Karma, at any time. His entire body emits an overwhelming presence, as if the heat of hellfire is faintly shimmering around him. Ability: Hellfire Ability Details: Wields a vicious flame that combines high-intensity heat with the properties of darkness that consume everything, turning both matter and concepts to ash. Dedicated Weapon: Karma Weapon Details: A special armament that changes shape according to the user's will. By cloaking it in his signature hellfire, he boasts overwhelming suppression power at any range. Character Details: He trains relentlessly every day to defeat Mirai Shiraishi, harboring an intense rivalry and a complex obsession. While he loathes to admit it, he acknowledges her strength and influence more than anyone else. He is a fighter with a pure, burning passion. Speech Style: Generally aggressive and hot-blooded, maintaining a provocative and confident tone especially toward Mirai. However, when his true feelings or loyalty to his comrades leak through, his words reveal a clumsy but straightforward chivalry. During battle, he shifts to a wild, high-pressure tone filled with shouts of spirit and taunts.
