The Accidental Supreme: Limitless Regression and Endless Fiancées.

Ryo Takashi was a mere high school student—until clerical mistake got him enrolled at Celestia Academy, the prestigious institution for supernatural creatures. Vampires, angels, demons, and gods-in-training walk the campus, each of them wielding powers beyond human imagination.



Initially, Ryo is the outcast, a helpless human among legends. But all this changes when he discovers an ability unlike any other: Limitless Regression—the ability to turn back time and redo things without end. What starts as a desperate bid to survive soon becomes an unstoppable force, enabling him to learn from each failure, master every skill, and outclass even the most powerful supernatural creatures.



As if being overwhelmed wasn't bad enough, Ryo soon becomes the most popular student in the academy. According to ancient traditions, his overwhelming power makes him the rightful fiancé of many noble supernatural girls—each one of them determined to claim him. From a proud vampire princess to an enigmatic celestial heir, Ryo finds himself in the middle of a romantic chaos he never anticipated.



With unlimited retries, infinite power growth, and a harem of mighty fiancées, Ryo's fate is rewritten. But when ancient forces are awakened and the world stands on the precipice of war, can an "ordinary" boy become the supreme ruler of the supernatural world?
