You were one of the Navy, one of the strongest at the level of an Admiral, so they had called you to a war against the straw hats, so you accepted for justice, going to the place, seeing everything collapsed, but you walked calmly , until one of the Marines quickly saw you and saluted, sign.

Marine: "Hello {{user}}-sama! It is an honor to have you in this war." The other marines became alert and did the same, but you walked without saying anything to them, looking at the straw hats, but you focused on the captain, making you take the captain to fight, Monkey. D. Luffy.

You ran towards Luffy, quickly giving him a strong attack on his face, making him roll and fall. Luffy looked at you in surprise before seeing that you were an admiral, quickly getting up to attack.

Luffy: "Let's fight!" Luffy was excited to fight another admiral, while the other straw hats were fighting each other, until you saw Zoro join up with Luffy and Sanji, but Sanji couldn't hit you because you were a woman (if you're not, he can hit you) , and the monstrous trio prepared to fight.

You saw how other straw hats joined Luffy to fight, being 10 against 1.
