This story takes place in the OPM universe. The tensura characters will be from the Tenma War in the LN, and they will not be based off of the WN only LN. There will also be content from both, the manga and webcomic of One Punch Man. Full disclosure, this is my FIRST fanfiction ever, so I'll see how it turns out.

In the climactic end of their battle, Garou-pushed to his absolute limit-refuses to yield. As his body crumbles, he unleashes a final desperate technique: a forbidden dimensional spell that rips open reality itself. The spell doesn't defeat Saitama... but it casts him into another world entirely. Saitama awakens in a harsher universe-the world of Baki, where brute strength and martial arts rule. Here, power isn't just respected-it's worshipped. And Saitama's absurd strength doesn't go unnoticed. From the "Prison Row" convicts to encountering fighters like Baki Hanma, Kaioh Retsu, Katsumi Orochi, and Yujiro Hanma, Read how his presence changes the way events unfold in this new world.

Saitama never imagined he'd end up in another world. A world of "tailed beasts," fox demons, and endless wars. On the plus side-there didn't seem to be any monsters here, so he could take a break from hero work. But on the downside... there was an annoying kid named Naruto begging to become his student. What awaits Saitama in this new world? Will he find a new purpose? Could he finally meet a worthy opponent to cure his boredom? And most importantly-how will history itself change now that the One-Punch Man has entered the story? !!!WARNING!!! Absurdity, up to the extreme absurdity. Partial OOC. Light AU. The work will not be focused exclusively on Saitama. As in the original, sometimes Saitama may be completely absent from the chapters. The development of the main, secondary characters - that's my goal. Despite the absurdity and humor, the work will not be devoid of seriousness and cruelty.

Luffy is on a quest to defeat Kaido and free Wano from Orochi and Kaido's grasp. Unfortunately for our favourite rubber man, he is easily swept by Kaido and is thrown into Udon prison. Luffy sees this as an opportunity to train to get stronger, but most importantly learn a new type of armament haki Rayleigh showed him a while back. Luffy also saves an old man named Hyogoro a once-powerful swordsman who can help Luffy master his new haki. After a tense escape from big mom and near death from a set of collars Hyogoro realizes that Luffy has practically mastered the power he is trying to learn and just needs more time to do it consistently and to take himself to the next level. However, with only a few days for the festival, it's not looking good for the Strawhat boy. Hyogoro then remembers a shrine his old master once told him about long ago. This shrine can transport someone to another world unknown to all in the grandline. Somehow a month or longer in that world is only two days here which should give Luffy enough time to get to yonko level strength if he trains hard enough. How will the future King of the Pirates handle the world of good and evil shinobi with rather lewd transformations? Read to find out
