is one piece episode 301 filler?

With the Gates of Justice opened to allow Spandam and Robin passage, the Marines and agents continue racing for their lives and they are surprised. Meanwhile, Kashii and Oimo continue carrying the Galley La workers, the Franky Family, and Sodom and Gomorrah while running away from the Buster Call.

They all cheer Luffy and Franky on. Luffy, still in Gear Second, stands before Lucci, who is still in half-leopard form.

The Straw Hat captain shows his determination to defeat Lucci, while Franky races towards Robin.
