One Piece's Most Devoted Son: Kaido, Please Stop Being So Filial

[Feel-Good Power Fantasy] [Hot-Blooded] [Growth] [Transmigration] [Multiple Heroines] [Lighthearted Comedy] [Fast-Paced] [Another World] [Filial Son] [Invincible Schemer]

After transmigrating to the world of One Piece, he becomes the young master of the Beast Pirates and Kaido's own beloved son, while also binding to the "Filial Son's Mischief System." As long as he performs an act of "filial devotion" that infuriates or harms Kaido, he can earn heaven-defying rewards.

And so, the story goes completely off the rails. Just after Kaido gets his hands on a rare Mythical Zoan, the protagonist feeds it to a dog. While Kaido is in seclusion cultivating, the protagonist gives his location straight to a Marine Admiral. When the Beast Pirates go to seize territory, the protagonist takes Yamato and empties Onigashima's treasury to fund his womanizing.

Looking at the crumbling Beast Pirates and Kaido, who's so furious he's spitting blood, the protagonist sighs with an innocent look on his face. "Dad, don't push yourself. I'm only doing this so you can enjoy your retirement early!"
