One Piece: Devour Fruit — Main Story: Setting Off for Whole Cake Island

On the boundless sea, the waters that should have been calm were now rolling and roaring with towering waves.
Two men were fighting atop the sea, and every collision between their strikes stirred up massive tsunamis.
But upon closer inspection, although their exchange created quite a commotion, neither of them carried the fierce aura of a life-or-death battle.
Rather than fighting, it was more like sparring, since one of them focused more on defense than counterattacks.
