Daikenja Riddle no Jikan Gyakkou

Daikenja Riddle no Jikan Gyakkou centers on Riddle, a young man who watched his friends and the world itself fall to the mysterious organization known as the Box of Malice. With the future reduced to ruin, he clings to a single impossible wish: to return to the moment before the catastrophe and stop it from ever happening. A thousand years later, that wish finally comes true. Riddle reverses time and awakens in his younger body, but the miracle comes at a cost: he must now live in the past carrying a thousand years of knowledge and experience that no one around him can understand. As the Great Sage Riddle, he uses that second chance to search for a way to confront the Box of Malice before it can tighten its grip on the world again. Every step forces him to balance memory and action, because he already knows what the future can become. Regret, fate, and the power that erased everything he loved now stand in his path, and every choice he makes could decide whether the world is saved or doomed to repeat its tragedy.
