The Great Wind of Pirates

This is probably a story about the protagonist falling in love and killing each other with fellow time travelers and natives in the world of One Piece. The tentative travelers include a fire-breathing dragon, a rough man who likes thunder, and a swordsman who regards pretending as his life. Of course, the most awesome one is the eldest brother named Wei who has grown up quietly. In the end, they will all usher in the awakening of God, and the times will begin to truly run wild. No one can predict the final future. (Ps: No harem, no following, no kingship, no struggle for hegemony, the protagonist is determined to be an elegant salted fish. I have ninety-nine and eighty-one ways to kill Momonosuke, and they are all funny. )
