I'm Just an Ordinary Marine

As for me, it's good to be in the navy, but I'm not doing it for justice, I'm just doing it for my own life... One Piece fic is a naval style. It will not mindlessly chase and lick the protagonist. The ideas are sharp and the purpose is clear. It is not a time-travel system without a system. It is a self-made fic with a large number of modifications. If you don't like it, don't criticize it.
