is one piece episode 266 filler?

Even after the Kairiki Destroyers are defeated by Oimo and Kashii, the members of the Franky Family continue fighting the giants. With Mozu and Kiwi's Ship's Bottom Dismantling Cut, Paulie's Rope Action, and Zambai's bazooka, Kashii is finally defeated.

He is then nailed down by Peepley Lulu and Tilestone. Oimo then takes on the remaining fighters, while Luffy takes out five hundred soldiers on his own.

Meanwhile, the members of CP9 meet together in the first full reunion in five years. Fukurou measures the physical strength of the CP9 members.
