This is the first book I am posting on this platform, so I ask for patience. My native language is not English, and I am not ashamed to say that I am using the so-called "Best Translator in the World" to help me with this work (DeepL translator). I was really trying to find fanfics that take place in the worlds of Baki, Kengan Ashura or the like, and although I found them, I only came across ones where the character gets supernatural powers that put him above any fighter from these worlds, and that frustrated me. A man needs to see two people fighting using their fists entirely, rather than creating interdimensional portals or something of that sort. So don't expect these kinds of powers here, because here there will just be the old way of solving problems. ---------------------------------------------------- It was a normal day for Yuji, going to school, then to the gym he was attending and finally home. A monotonous, but pleasant routine. There was no cause for pride, much less shame, so for the teenager that was enough. As always, everything was going as it should. That was until the moment when, looking in the mirror, the boy's whole perspective seemed to change. Facing someone who looked like him, but at the same time, was not him, Yuji sees himself in a similar world, but which is certainly not his. Crossover world of animes, including Tokyo Revengers, Baki, Kengan Ashura, Holyland, Hajime no Ippo and others that can easily be included in FF if readers have ideas.

Everyone must have a few regrets in their lives, and for Mykel regret was publishing this novel on the internet. Because of this failed novel he wrote, made his career down the hill as an author. Thanks to this novel, he lost his passion and he lost everything that he had. "I wish I can destroy this novel so that nobody will be able to see it or remember it anymore," Mykel said. That was what he wished for, and for some reason, he went inside that novel of his and as himself in the story that didn't suppose to exist? Mykel smirked and grinned as he looked at the system. [You are the creator of this world, you will have the access to the command system. You are free to do anything as long as it is listed in the command system] [Please enjoy and have fun] "Heh, then I will turn this world upside down," Mykel said as he glared at the notification in front of him.

When I died I didn't expect to wake up with dark beings of immeasurable power looming over me. I didn't expect to be given new life in a brand new world. Now, armed with a powerful system that makes me stronger after every fight, I might be the last thing standing between the multiverse and absolute annihilation. As I complete quests, defeat foes and become stronger, I still don't know if I'll be able to save this world, my old world and all the worlds in between. "And below... the MAW beckoned..."

Eshwar is the name of the author who transmigrated into his own novel after his death. Eshwar’s death was caused by his own magic which he had yet to control. Why? because I didn't think I would seriously die!!!! Anyway.... my novel's protagonist is a selfish person. why you ask? because I wrote him and I wanted him to be like me. Muhahahaha, ha. I reincarnated into my novel! and that to as a villain who dies in the first half, will I stand still and die? Of course not, I may have reincarnated as a villain but its not like I will live like he did. I'll live my life as I want! and kill all the other villains. Why? because I love the world I created, hahaha, ha.... (real reason: I love to fight.), who else will get the chance to look at the world they have created? System I created is messed up for some reason and is doing everything on its own!!??? we'll see how it turns out with everything messed up, well(sigh...) Oh, but because i have reincarnated as a villain, I got a new problem and that is, I'm handsome (sparkles), I have to say, handsome people have their own problems. ==== SLOW START.

After saving a person from Truck-kun, the damn truck went rogue to kill me, and sent me to the void to be tortured. But Creator took a pity on me and saved me.
