44 parts Ongoing What if Tempest was never founded?
Rimuru missed his opportunity to save the lives of those who would've become some of his first and closest friends in his new slimy life, leading to him never founding his country. Many twists and turns occur as he stumbles along, mostly alone, trying to uphold the promise he made with his sworn brother, as well as carry on the will of the woman he lost early in his journey.
This darker turn on the story we all know pushes our favorite slime to his limits in many ways, but will it still have a happy end? Can Rimuru survive this harsh new world without most of his friends? Will he still be the same person after enduring many hardships?
