is one piece episode 396 filler?

Saint Charlos arrives at the Human Auctioning House, glad that the auction has not ended. He kicks his slave repeatedly, blaming him for his lateness which caused him to miss most of the auction.

The Straw Hat Pirates notice his arrival and overhear Charlos expressing his desire for a mermaid. Disco introduces the next slave, Lacuba.

However, the slave collapses and blood drips from him to the floor, eliciting screams from the audience. Panicky, Disco orders for the curtains to be pulled.
