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.

In this story, rimuru has died but due to his wishes he went back in time and become a slime? now with his new found powers and skills, he strod off into the unknown and it seems he is not a normal slime but a demon slime? and he is the only SENTIENT BEING IN THIS REALM! Now surrounded by mindless demons, what will this slime do? Rimuru due to his strong if not stronger soul changes his gender into a male Instead of veldora, veldanava will be his 'sworn friend' since there are almost no other sentient beings other than a few Rimuru will also later evolve into a primordial instead of being one from the beginning. don't ask me how I don't know either Rimuru and ciel will also be with each other wayyy longer hence they become a bit 'EXTREMELY YANDERE ON EACH OTHER' uhmm a bit obsessive. also my first time writing a story + haven't read the light novel but kinda know the order and story to an extend + I'm a 6th grader so I don't know a lot of words I can use for my story to express my story BUT I hate spelling mistakes and will probably not make any but a few. I do not own the tensura series or light novel it belongs to fuze san(I think that's his name?) also if any one copies my story without my permission I WILL SEND YOU TO JESUS Taking inspiration is very much allowed
