is one piece episode 246 filler?

Lucci reveals himself to be a user of the Neko Neko no Mi, Model: Leopard, a Zoan-type Devil fruit that turns him into a leopard. Meanwhile, the first floor of Iceburg Mansion is set on fire, so the members of Galley-La run upstairs to check on Iceburg.

Lucci keeps them at bay using the Rankyaku move, essentially cutting the entire mansion in half. Lucci defeats both Luffy and Zoro, sending them both flying into the sea.

Nami is also knocked out and thrown out the window. Paulie and Iceburg are left tied up near the fire.

The members of CP9 then leave to get the blueprints from Franky.
