Sengoku features in a post-timeskip cameo amid the Marine response to Delta Island’s events. He mobilizes with the Buster Call fleet deployed to the island. His involvement activates after antagonist Douglas Bullet unleashes his awakened Devil Fruit powers, prompting Fleet Admiral Sakazuki’s order for a second Buster Call. Sengoku operates in an administrative and authoritative capacity during this military action, aligning with his Inspector General role overseeing Marine activities. The character abstains from the central conflict and refrains from interactions with pirate factions throughout the film.
