One Punch Man: the Beginning of the War on the Top

One Punch Man Saitama, by chance, travels to the world of One Piece, just when the war breaks out. He saw Whitebeard's arrogance and admiration, so he intervened in the battle out of interest. Akainu punched to stop him, Saitama flicked his fingers, the magma collapsed, and the general retreated. The battlefield changes suddenly because of his thoughts, and he acts heroically, but based on his true heart, the unintentional legend has shaken the order and legend of the entire sea.
