is one piece episode 913 filler?

A drunken Kaidou makes an appearance in Okobore Town in his azure dragon form. Law explains to Kin'emon that he, along with the Straw Hats, were identified by the Beasts Pirates.

He explains that Kaidou dealt in an underground SMILE fruit operation led by Doflamingo. However, because Luffy destroyed the factories in both Punk Hazard and Dressrosa, he ended the SMILE fruit operation, meaning that Kaidou is in mad pursuit of Luffy.

Luffy starts running toward the town. Law chases after him while the others stay behind to avoid getting exposed again.
