Anime Notes

 * The anime adds the following:
 * Additional dialogue before the revelation of the Scabbards traitor, mainly the samurai speculating on the traitor's possible motives, then Kin'emon blaming his own incompetence for allowing one of his allies to be coerced into spying for Orochi before Kikunojo talks him out of it.
 * The reveal of Kanjuro's betrayal is expanded. In particular, Kanjuro revealed he leaked the first plan of the Nine Red Scabbards to Kurozumi Orochi, and gave Jack the Vivre Card required for him to reach and destroy Zou.
 * Kanjuro drawing the snakes to bind Shinobu.
 * The Beasts Pirates firing cannonballs at the samurai, and Ashura slicing one cannonball in half.
 * Law and Kid get an added dialogue each.
 * The anime changed the following:
 * In the manga, the Straw Hat Pirates appeared before the Beasts Pirates' ship was attacked.
 * In the manga, the Thousand Sunny's sails are folded when the Straw Hats arrive, but in the anime they are spread and seen patched up.
