is one piece episode 376 filler?

Bartholomew Kuma towers over everyone. Many of the witnesses there wonder what kind of powers this man could have to cause so much destruction.

Lola is upset as she and the rest of the Rolling Pirates had just finished suffering through the nightmare of Gecko Moria, but with Kuma in their midst, it seemed their suffering was far from over. The other members of the Rolling Pirates decide to fight as the Straw Hat Pirates already went through a lot to defeat Moria.

Zoro suddenly speaks up saying that Kuma challenged him, intending to take down the Warlord of the Sea himself.
