One Piece: I Beat Ace and Became the Marines' Strongest Sword

When pirates slaughtered his family, Ares vowed never to sail under the Jolly Roger. Raised in Foosha Village, he rejects Luffy's invitation—pirates can't save this rotten world, only the fiercest lightning can purge its sins! Training under legendary swordmaster Koushirou alongside Kuina, Zoro, and Sanji, the four swear brotherhood and join the Marines with one mission: absolute justice. No pirates spared. No Celestial Dragons safe. In a world where even heroes wear chains, Ares will become the storm that cleanses everything.
