Daikenja Riddle no Jikan Gyakko

A premise with promise that crumbles in execution: the idea of a sage journeying backward through time with a thousand years of knowledge in tow sounds captivating, yet the anime fails to harness that inherent tension. What could have been a contemplative adventure about the burden of memory becomes a mechanical, directionless slog.

The story follows Riddle, a young man who lost his companions to a mysterious group known as the "Box of Malice." On the brink of despair, after 1,000 years, Riddle eventually achieves the ability to reverse time. With a thousand years of knowledge and experience, the Great Sage Riddle journeys to the past.
