is one piece episode 177 filler?

Due to the distraction caused by Aisa and Nami getting swallowed by Nola, Ohm attacks Zoro and Wyper. Ohm counts the total number of people left and came to a total of ten men and two animals.

The Shandia at the Upper Ruins become upset at Ohm and try to attack him but were defeated by Holy and killed by the piercing of the Iron Cloud. At Ohm's command, Holy ran around and created a dome-like cage in the form of barbed wires.

This trapped in all the fighters, hence, called a death match.
