One Piece: Get the power of the Titans at the beginning!

Soul-piercing pirate! Oh! If you have a system, it will be fine! Besides, isn’t it standard for time travelers to have systems? It would be strange if it didn’t exist, right? Readers wouldn’t have it, right? No way! No way? This year is One Piece 1480! There are still four years until the Battle of the Valley of the Gods! Roger is not king! The Yonko is still just a crew member! The Shichibukai are even more like a bunch of dolls! Garp was only a lieutenant general during the Warring States Period! This time I want to punch Sengoku and kick Garp! The invincible player who dominates the world! ． ． ． ． ． ． Is the King of Heaven so strong? Anime bullies me! Does it have to be the protagonist?
