Anime Notes

 * The following scenes are added:
 * Vergo attempting to strike Law before getting cut into more pieces.
 * Rubble falling in the secret room.
 * The anime shows that Caesar did not petrify all of his subordinates in the R Building first floor before Luffy starts preparing for his Gear Third attack.
 * Unlike the manga, Caesar's Shinokuni form has a clash against Luffy's Gomu Gomu no Grizzly Magnum. When it becomes clear it has no effect on Luffy and that the Grizzly Magnum is pushing toward him. Ceaser offers Luffy to be his (Caesar) subordinate in his panic.
