is one piece episode 193 filler?

Luffy delivers to Enel his finishing blow with this golden ball arm, causing the Golden Bell to ring and fall and the golden ball to shatter. The ringing is heard by Cricket and the Saruyama Alliance all the way from Jaya, and all the other people in Sky Island.

The Straw Hats rejoice upon hearing the beautiful sound of the bell. Having confirmed the existence of Sky Island, Cricket surmises that the "giants" they see in the cumuloregalis clouds were just shadows of the Sky People living in Sky Island.

He then cries in relief knowing the Straw Hats are safe.
