is one piece episode 717 filler?

Leaping toward Diamante, Kyros slashes at him, resulting in a shockwave that blows Diamante back. While dodging and blocking Kyros's attacks, Diamante expresses disbelief at him being able to move during Death Enjambre.

After moving away from Kyros, Diamante asks him if his body is an iron ball, only to note that Kyros must be feeling immense pain after seeing a spiked ball land in his arm before demanding to know if Kyros is a ball of stupidity.
