Kizaru swaps identities with Sanji, Sengoku with Jinbe, Bullet with Franky, and Akainu with Robin.

One day, a giant projection screen appears across the world of One Piece and begins playing videos.

The video is told from Garp's perspective. As a child, he is saved by Shanks and vows to become the Pirate King.

The Enies Lobby battle.

Garp: "Sakazuki, hurry up and say you want to live!"

Akainu: "I... I want to live! Take me with you out to sea!"

The Enies Lobby battle ends.

Luffy, the hero of Marine Headquarters, appears and knocks Garp down with one punch.

Kaido: "What? Garp, you said Luffy was your grandpa?"

Everyone watching the video is stunned.
