One Piece: All My Sons Are Admirals and Emperors

The good news: I’ve transmigrated into the world of Pirate King and gotten a new life. The bad news: I’ve transmigrated to a time before the Rocks Pirates disbanded, and I’m inside the body of Katakuri, Charlotte Linlin’s second son, who loses all sense of kinship when his food cravings strike. After transmigrating into Katakuri, he gains the Family Astonishment System. By making family members stronger, he receives rewards in return. So let’s make the Charlotte Family the strongest family in the world! And so the world is astonished time and time again. “Daifuku, my foolish little brother, your big brother is giving you a Rumble-Rumble Fruit!” “Oven, do you think this Woods-Woods Fruit suits you?” “Mom, I think it’s time the Charlotte Family had a new leader!” “Roger, the title of Pirate King means nothing to me, Katakuri!” “Whitebeard, I’m the strongest man in the world!” Years later, after Whitebeard dies, his new captain decides to join the Charlotte Family? The Beast Pirates merge into Totto Land as a group? The one-eyed man at Revolutionary Army Headquarters stares at his most trusted companion and cries out in disbelief: “How can this be? How can you be members of the Charlotte Family?!” When Sakazuki moves against Totto Land, several Marine Admirals shout to Katakuri: “Father, how should we kill him?” Imu says nothing as dozens of Yonko-level fighters surround them. My name is Katakuri. I wield the Three Types of Haki and the powers of three Devil Fruits! I can do anything, above or below the heavens!
