One Piece: The Air-Airy Fruit

"I will gain power. Even if I have to give my soul to a demon, I'll trade it for enough power to destroy this world." A different protagonist, a different Pirate King story. There is no heaven-defying cheat, only the story of the protagonist growing stronger step by step. The Pirate King heroines won't all end up with him, but there will still be quite a few.
