Surviving at Sea: Every Day Is a Battleground

[Female-oriented + character growth + funny and heartwarming + redemption + beloved by all]

[New author, OOC warning. The timeline may also get a little confusing, and there will be a ton of original additions. The author mostly wants to indulge in a few personal fantasies, so please don't read if that bothers you, everyone!]

[There may not be much romance while the heroine is still a little kid. She'll grow up after returning to the Whitebeard Pirates, and will experience the Summit War.]

Liya is the little sister of the Whitebeard Pirates. She was captured by the despicable Celestial Dragons on Sabaody Archipelago, and the whole crew began training like mad to save her. Later, they realized that before their little sister had even grown up, someone already seemed ready to sweep her right off her feet. Where did all these people come from?!

Bonus scenes:

A certain Marine admiral stared at the man before him, who was brandishing Murakumogiri, and fell into deep thought. “If I beat up my future father-in-law, can I still marry his daughter? Asking for a friend, and it's urgent!!”

The constant grumbling of a certain second-in-command: “How do you steal away the girl you like when she has over a hundred big brothers?”
