is one piece episode 454 filler?

Sanji is chased by okamas to Caroline - the queen's stand in. Sanji agrees to fight Caroline, Kamabakka's strongest warrior, in return for passage from the island.

Sanji fights in a dress (Kamabakka terms) and is embarrassed because Caroline was looking at his underwear while fighting. After he realized that, he started kicking lower - with taunts from Caroline. "She" then picked him up and threw him up, and he became scared like a girl.

He starts thinking that he is losing himself, and loses the fight.
