Daikenja Riddle no Jikan Gyakko

Riddle was once an ordinary young man until tragedy struck, tearing away everything he held dear. His closest companions were taken from him by a mysterious and sinister organization known only as the "Box of Malice." Stripped of his allies and left entirely alone, Riddle found himself standing on the very edge of despair, burdened by grief and powerless to change what had already happened. Yet, rather than surrendering to hopelessness, he endured. For one thousand long years, Riddle dedicated himself to relentless study and perseverance, driven by a singular purpose. After a millennium of tireless effort, he finally unlocked an extraordinary power: the ability to reverse time itself. No longer the helpless youth who lost everything, he transformed into the Great Sage, armed with a thousand years of accumulated knowledge and unparalleled experience. Now bearing the weight of ten centuries of wisdom, the Great Sage Riddle embarks on a monumental journey back to the past. Equipped with his hard-won mastery over time and a deep understanding of the world, he returns to the era before his greatest loss. With history laid bare before him, he sets out to confront the Box of Malice once more, determined to rewrite fate and reclaim the future that was stolen from him.
