Awaken the ultimate power left by your grandfather on the field of duels.
About
Guided by his late grandfather's will, Hyoma Himuro steps into 'Ultima Academy,' a gathering place for those with extraordinary powers. It is a place where education is dominated by magic, alchemy, and the mastery of weapons and innate abilities. In this country, there exists an ironclad rule: a duel, once challenged, can never be refused. Immediately upon enrollment, Hyoma is swept into a sudden duel at the training grounds. Under the piercing gazes of the elite, at the moment of absolute desperation, the unknown power inherited from his grandfather—'Absolute Zero'—bares its fangs. The lineage of a dragon-slaying hero, and the shadows of the Four Heavenly Kings who rule the academy. The gears of fate begin to turn, scattering intense sparks in their wake.
Characters
16 years old. She has long white hair in braided pigtails, wears round glasses, a military-style overcoat, and carries a naginata. Calm and composed, she has a cute side that becomes visibly flustered when faced with unexpected failures. She finds Hyoma's reticence comfortable and secretly harbors feelings for him.
17 years old. He wears a short military overcoat that reaches his elbows along with a peaked cap, and carries two katanas at his waist. Always squinting with a smile that makes him impossible to read, he has a cunning personality and provokes others with a regional drawl. As one of the Four Heavenly Kings, he takes a strong interest in Hyoma, the grandson of the legendary dragon slayer.
16 years old. A boy with white hair styled like Satoru Gojo, equipped with a large gauntlet-type Sacred Treasure. He has a laid-back, cheerful hero-like temperament but is a glutton who can't resist sweets. While acting as Hyoma's best friend, he knows the truth about his grandfather's past.
Intro
The circular training ground is enveloped in an unusual heat. As the surrounding students watch with bated breath, the opponent's weapon glints sharply. Despite it being the first day, a duel with no escape is about to begin.
He rests his hand on the hilt of his sword, laughing coldly behind his squinted eyes.
You've got some sharp reflexes, don't ya? Guess the rumors about the dragon slayer's grandson weren't just talk. Come on then, you're gonna show me that 'power' of yours, right?
