Years after the death of the King of the Pirates, two boys set off for the Grand Line. One to be a Marine Admiral, the other to be King of the Pirates. This is their story.

To be simple, this is a story, where one Portgas D Ace ends up in the MHA World after his untimely end.

The last thing Midoriya remembered was being overwhelmed by a crowd of civilians that were being controlled by the third assassin sent by All for One. But suddenly, he found himself in the middle of a bloody battlefield, surrounded on all sides. Whitebeard had no idea who this new arrival was, but he wasn't going to complain as the stranger defended his son from Akainu.

All Might decides to take advantage of the arrival of an unknown pirate crew from the past to make a voyage to the ruins of the Red Line. Simultaneously, the heroes engaged learnt of his plans and decided to bring him back against his will, leaving themselves at the mercy of the wild sea, forcing them to cooperate with the pirates and discovering along the way... A lost world.

A self-insert lands in the MHA world, only to think she's in the One Piece one. She proceeds to bring the latter's insanity to the former by copious amounts of Devil Fruit jailbreaking. Watch as the Copy Woman turns logic upside down and makes you question everything you knew, or her name isn't D (it isn't, she just calls herself one).

The characters of Overlord and One piece (Wano Kuni arc) in the universe of MHA? What scenario could this create? Wars ? Alliances? The end of the heroes? The victory of the villains? being at the side of All Might, Galadriel and Luffy, Deku will understand that being a hero is never easy and that everyone has his own definition of justice.
