Differences from the original chapters
The special chapter starts and ends with a view on the world, similar to Dr. STONE.
After Zoro's defeat, Luffy's attempt to attack Mihawk is extended where Luffy tries a second attempt to attack Mihawk after doding Luffy's initial attack, but the latter is still able to dodge all of his attacks.
