is one piece episode 27 filler?

After Luffy destroys the Baratie's fin, Krieg orders Gin to kill Sanji. Gin hesitates, as Sanji was the staff member who fed his crew.

Pearl attempts to kill Sanji himself, but is attacked by Gin, who destroys his front shield and knocks him out. Gin decides to personally battle Sanji as a thanks for his generosity, while Krieg focuses on Luffy.

Gin, dubbed the "Man-Demon" for his extreme cruelty, uses his Man-Demon tactics against Sanji, armed with two weighted tonfa. Despite Sanji initially striking Gin to the ground, he quickly recovers, cruelly beating Sanji and gravely injuring him.
