is one piece episode 633 filler?

As Luffy is about to register for the competition, Franky tells him he can fight however he likes, but he has to promise not to reveal his name to anyone. Luffy agrees, but forgets and starts signing with his real name until Franky stops him in time by punching him in the head.

Luffy enters the competition as the 556th contestant "Lucy" and is led to the dressing area. Franky stays behind with Thunder Soldier and starts questioning him about the Donquixote family, the factory and whether the toy soldier was born in Dressrosa.
