All characters, settings, and story elements belong to Fuse, the original creator of That Time I Got Reincarnated as a Slime (Tensura). This work is not official canon and is purely a creative exploration of the world and characters in an alternate universe scenario.

What if the war with Falmuth is worse than the anime... What if Rimuru is delayed? What if eren didn't came to tempest that night? What would happen to the world if the kindest person turned into the worst thing that could happen to humanity or the world? This story is about a mistake humanity made that threatens its complete extinction...

Everything had a counterpart because without two opposite things there was no balance. Even the creator Veldanava had an opposite who he calls his equal and twin brother. Watch as they learn more about mortality and how it makes their immortal life a rollercoaster, even when tragedy struck. AN: I do not own tensura nor do I know the characters the best. There are a few changes to the story which do not exist in the actually story of Fuse. Rimuru Tempest will appear later. Slow updates.

So Rimuru, who has forgotten everyone yet remembers everyone, has jumped into the past. But the price of jumping into the past without Ivarage following him was to heavy... all of his power has disappeared. Now, a slime with two unique skills and the memory of a novel called Tensura has begun a new journey in the distant past, when Veldora was just born.
