is one piece episode 470 filler?

Luffy is running towards Ace but Mihawk stands directly in his path. Deciding that he does not have the time to deal with someone as strong as Mihawk, Luffy activates Gear 2 to steer clear of him.

Ivankov continues his fight with Kuma, as two of his Newkama soldiers try to hold off Mihawk from attacking Luffy. They hint towards some sort of past experience with the swordsman, who replies with "I do not remember the face of every worm" after defeating them both with a single swing of his sword.
