is one piece episode 298 filler?

With the Gates of Justice about to open, Sanji believes the Straw Hat Pirates can still save Nico Robin if Usopp does something. Sanji implores Usopp to leave while he faces off with Jabra.

The cook tries to take Jabra's Iron Body Kenpo but is knocked back. Just then, Usopp gets an idea to rescue Robin.

Before Jabra can give chase, Sanji kicks the wolf-man in the face. Jabra gets up and tries a Ten Finger Pistol, but the cook dodges and retaliates with a Troisième Hachis barrage.
