is one piece episode 534 filler?

Luffy leads Shirahoshi out of her tower inside Megalo while Brook and the Minister of the Right tells them to stop. When Brook and the Minister see that Shirahoshi is not in her tower, they are attacked by human pirates and tell them to take them to the switch to open the palaces gates or they'll die.

The story shifts back a few hours to the Fish-Man District with Decken explaining his Mato Mato Curse to the humans and just as he calls out for a demonstration, a voice shouts out for Hody Jones.
