After living for billions of years and reaching the end of everything, Rimuru Tempest realizes one painfully stupid truth: he may have won at life, but he completely fumbled love. He treated everyone precious to him like family, ignored every confession, dodged every chance at romance, and only understood what he was missing when the universe had already gone silent. Watching him drift alone in the void for over three billion years, Ciel finally snaps. With one forbidden decision, she rewinds time itself and sends them back to the distant past, before Rimuru was ever Rimuru. Now reborn as human Satoru Mikami, armed with all of his future god-tier powers but none of his memories, he's thrown into a world that has no idea a final-form god has just arrived way too early. With Ciel now at his side, canon is doomed, fate is panicking, and Satoru's second chance at life is about to become a chaotic mix of mystery, overpowered nonsense, emotional reveals, and harem-level romantic trouble. Because this time, Ciel only has one goal: Make sure her master stops being dense before history embarrasses him again.

In the battel against Chronoa, Luminous decides to help Rimuru subdue Chronoa rather than leave it all to him.

But time travel doesn't just happen without consequences, especially when one of them travels to a place they shouldn't be at that time. The duo of Vampire and Slime must navigate those changes and paradoxes of time travel, while trying to understand what exactly do they feel to each other.
