is bleach episode 275 filler?

Coyote Starrk continues to battle Captain Shunsui Kyōraku. Starrk fires a Cero, surprising Shunsui and he dodges.

Shunsui praises Starrk, claiming that the Cero he had fired is much more powerful and faster than the ones he had heard about, and notes that it is difficult to avoid such an attack. Starrk says that since he showed him his Cero, Shunsui should at least get serious, and walks toward him, but Shunsui backs away.

Starrk claims that Shunsui’s outfit makes him look absurd, then proceeds to fire a Cero without taking some sort of firing stance, shocking Shunsui and the Cero demolishes a building.
