is one piece episode 983 filler?

Kid and Luffy race to Onigashima, with Jinbe controlling the Thousand Sunny. Meanwhile, Raizo briefs the plan.

Kid and Luffy would enter through the front gate as decoys while Kin'emon and Denjiro each lead another decoy group through the mountain path. Starting the plan, Kin'emon sets sail while the Heart Pirates go underwater in their submarine.

The allies enter to find Onigashima vibrantly illuminated, with the guards at a banquet and unprepared for enemy attacks. Usopp knocks out the few intoxicated guards on lookout, allowing the others to safely disembark.
