is one piece episode 668 filler?

The battle is set to begin as all four contestants and Diamante enter the ring. Gatz reminds the audience of the top tier Logia Devil Fruit waiting for the victor.

Although Lucy makes a mental note of Burgess as a member of the Blackbeard Pirates, Rebecca in turn makes a note of Lucy, saying that he is not the same man. However, the group is interrupted as three gladiators rush at Rebecca, saying that they refuse to be beaten by her and that they cannot accept such an outcome.

Diamante steps in, telling the gladiators that "results are results" and holds his cape in front of his body.
