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
