is one piece episode 863 filler?

After he pummels Luffy into the wall with Chikara Mochi, Katakuri wonders why he is not giving up. Luffy charges toward him once again and tries to attack, but Katakuri dodges everything Luffy throws at him and successfully counterattacks.

He then creates several Muso Donuts and assaults Luffy with many Chikara Mochi punches. Luffy does his best to dodge most of them, but is eventually caught and punched into the wall.

Katakuri is then surprised as he foresees what Luffy's plan is, and Luffy concentrates in order to utilize his strengthening Haki.
