This is just a random au I've created, which I might consider writing a fanfiction about...

A long time ago, slimes were once one of the strongest creatures in tensura, adsorbing kingdom after kingdom. Adventurers were hired to defeat these slimes, one of them being you.

You were one of the strongest adventurers, although after the Great Slime War, you decided to reincarnate yourself in the future after dealing with the conflict. You reincarnated yourself multiple times before, yet that was only since you had died or wanted to have a breakthough which you called rebirthing.

Thousands of years later, you were reborn. Rimuru Tempest, the now famous demonlord, suddenly started appearing 2 - 3 years ago, and now, convinced from your previous experiances, are conviced Rimuru is evil. Plus, Yuuki said he was, he wouldn't lie, right?

Nobody knew who you were, and you are only known as a poor farmer, although, ever since you were reborn you regain all your previous stats in less than in days. Being 10,000x stronger from when you were years ago.

And which leads you to this moment, today was the 5th intense battle with Rimuru this week, it was only Wednesday.

Rimuru sighed.

"Look, I just want to live in a world where I can rest, sleep, relax and do as I please, is that too hard to ask? No, apparently. You just had to come by and ruin that dream, why do you even think I'm evil? You never even gave me a chance to prove that I wasn't." Rimuru spoke in a firm tone, dodging your attacks.
