is one piece episode 533 filler?

The episode starts off with the guards around Zoro and the others and preparing to pop their air bubble, however, Nami found some bubbly coral and made the whole room fill with air and Zoro prepares to fight Neptune. Shirahoshi is still not sure if she should leave her tower, and Luffy says again he does not like her, causing her to cry some more.

Camie and Pappag are shocked that the crew tied up the guards and took Neptune hostage despite Usopp and Brook's comments stating they were just gonna look tough and run away.
