San Tong Livestreams Raising Kids in the World of One Piece

With just two hundred years left to them, three Systems wandering together through the void suddenly found a baby. The three idle Systems: Whew, we've had so many generations of Hosts, but we've never tried raising a baby! So, figuring that since they'd found the baby, they might as well keep it, they took the child to the nearest world and started raising her. But there was a problem. How were a Strongest System, a Dress-Up System, and a Livestream System supposed to raise a child?! Strongest System: Leave it to me! I've raised a Host who could defeat anyone with one punch! I'll make this child even stronger than the Pirate King of this world! Dress-Up System: Mommy won't allow the girl we're raising to go bald like your former Host! Livestream System: Stop arguing. Let me open a livestream for the other worlds first. If I don't stream now, I won't be able to access the livestream shop, and if I can't access the shop, the kid will starve! Zella, who can survive in the void and isn't actually a baby: ... When Zella grew up, she had a ship gifted to her by the Dress-Up System. The former Hosts of the Livestream System often came aboard for a visit, and she also had a crew she summoned using items provided by the Strongest System. Since all her crew members were people who had returned to the world after death, she named her ship the Old Era. Pairing: Ace A half-crackfic. Everyone, Systems included, will help each other heal. None of them are perfect. Core theme: Our meeting was fate, and that means I was destined to be your salvation.
