We all know how Rimuru got reincarnated and started his adventures, however... In this story timeline, he was reincarnated millions of years before as a human. He had his ancient adventures and life with his friends, worldly and otherworldly alike, before entering his second reincarnation cycle into the present. Little did he know that, the world would change so much since his temporary demise and that loose ends of the past continue to linger and cloud the future in mystery, both his and the world in general. It's up to him to explore his destiny and confront what was left unfinished in his past, for he walks a road of his destiny, a road with his own challenges, a path that guides him to become greater than he could ever expect.

If you hear the word reincarnation nowadays, it is usually an untrue fairy tale of being transported into a new world and overcoming the greatest evil to bring about a glorious peace. Yet that unrealistic scenery gets pummeled by the extent of reality. A world too cruel where strength was all that mattered and moral principles were unimportant. The life of the weak is as cheap as dirt. Everyone has died. The same goes for me. Yet again, the raging rides of fate shifted me into a new world once more. So... peculiar. Absurd. Cruel, even. The curse of immortality, stripped of the right to rest. Maybe I just have that lingering desire to live despite it all. Destruction shall befall those who gets in my way. Permissiveness I shall embrace. Nonintervention to those who knows their place. A new reality's beginning... heralded by life and death.

80 years have passed since Yuuki's defeat. Rimuru, after dwelling for countless years at the end of time and space, has surpassed Veldanava in terms of strength and is, therefore, the strongest being in the Cardinal world. With his strength, he easily dealt with the aftermath of the final battle and accomplished his dream of coexistence between monsters and humans. Although he is happy with the results, his daily routine consists of constant paperwork. During one of these boring days Ciel, who is worried about the mental state of her master, suggests creating an alternate Timeline and traveling back in time. Rimuru, not wanting to do everything over again, comes back with an alternative idea. Going back in time but with one addition: instead of traveling to his original time of reincarnation as a slime, he decides to go much further in time and become one of the ancient demon lords.
