One Piece: Ace, Say You Want to Live!

Roy transmigrates into the world of Pirate King and becomes Whitebeard's adopted son.

After unexpectedly awakening the [Strongest Marines System], Roy has no choice but to leave the Whitebeard Pirates and join the Marines so he can grow stronger.

He roams around killing pirates and completing System missions, earning insight into the Three Types of Haki and gaining the fearsome nickname “One-Punch Vice Admiral”!

But the Paramount War arrives as expected, and Roy, now a Marine Vice Admiral, meets Whitebeard once more...

The Three Admirals stand ready, the Shichibukai line up on either side, and the two top combatants, Garp and Sengoku, are there in person to oversee the battle.

Roy slowly steps forward and looks toward the Execution Platform:

“Ace!!!!!!!!”

“Say you want to live!!!!!!!!”
