is one piece episode 923 filler?

Tonoyasu takes Zoro to his hometown, Ebisu Town. The town is poverty-stricken like Okobore Town, but its citizens laugh despite their circumstances.

Citizens of the town claim that an unknown thief named Ushimitzu Kozo steals from the rich and gives the money to poor tenements. A girl offers him a cup of clean water, which to them is a luxury.

Meanwhile at the Flower Capital, Orochi demands a luxurious dinner, wastefully rejecting many of the prepared meals offered to him. He also demands several geishas, including Robin undercover, to dance for him.
