is one piece episode 925 filler?

Sanji activates his raid suit can, transforming into a more powerful, scientifically advanced Stealth Black. Although he is formally named Stealth Black in Germa 66, Sanji decides to name himself Soba Mask.

Sanji begins fighting Page One, knocking him down with a kick in the throat. Page One attacks with his claw, but Sanji then blocks the attack with his cape, which turns into a solid shield.

Most notably, Sanji's suit allows him to turn invisible, allowing him to attack Page One with super speed. Page One collapses and transforms into his hybrid form.
