[One Piece + Gintama] Whitebeard's Legacy (Ace BG)

She has no idea what kind of inheritance other people's grandfathers leave their granddaughters. Her own grandfather, though, left her a whole bunch of so-called "uncles," along with the title of "Captain." Before she transmigrated, she was just an ordinary, unknown makeup artist. After she transmigrated, she first became an orphan, then went to war, and even ended up in prison, where she almost got executed. Maybe her last life was just too uneventful, so this life had to be full of calamities. But that was only the beginning. She thought she'd once again amount to nothing, living off others and waiting to die, but then she transmigrated again. This time was even more dangerous: she landed right on a battlefield, in a place where people could use "superpowers." Unfortunately, she didn't seem to have any superpowers herself... Here, the First Division Captain is a babysitter because he has a very troublesome captain of his own. Here, a Revolutionary Army officer is a "girl dad," with the nerve to wipe out anyone who dares lay a finger on his daughter. Here, the Second Division Captain is under immense pressure: not only has he inexplicably gained a fiancée, but the first time they meet, she points a gun at him and seems ready to shoot her own father-in-law at any moment. Here, the protagonist is under a lot of pressure too. Everyone in the pirate crew is the same generation as her mother, so she's surrounded by a whole bunch of "uncles"! Theme:
