is one piece episode 915 filler?

Luffy pummels Kaidou using his Elephant Gatling Gun move. Despite this, Kaidou is unharmed and he knocks Luffy back with a belch.

He then proceeds to attack Luffy with his tail and shoots fireballs, but Luffy evades the attacks and knocks Kaidou to the ground using his Grizzly Magnum move. Kaidou is largely unharmed by Luffy's attacks and turns back into his human form.

He gets up and is dizzy from intoxication, but Luffy continues to fight, transforming into his Gear 4: Boundman form. He pummels Kaidou with the Kong Organ Gun move, sending him flying and crashing into many buildings.
