is one piece episode 415 filler?

At the arena, Boa Sandersonia and Boa Marigold apologize to Hancock for losing, but Hancock says it's fine and Luffy looks over at Marguerite's body and is relieved to see she's fine. As Luffy is done checking her, he looks up and asks Hancock if she's gonna fight him now, but Hancock says she won't and is done with all the fighting and just wants to end things now.
