is one piece episode 451 filler?

The whale sharks hop happily through the water and Jinbe tells them to carry the ex-prisoners to his newly captured Marine ship. The whale sharks form a line while Luffy and the others jump across one by one until they reach the ship.

The prisoners celebrate their victory, but Jinbe says there's one more obstacle to freedom. As the prisoners thank the whale sharks, Ivankov wants to treat Inazuma checking for medical supplies.

The prisoners insult Magellan thanking Buggy for their freedom. Desperate, Magellan wants a ship to chase the pirates down determined to carry out their death sentence.
