is bleach episode 278 filler?

The captains of the Gotei 13 are exhausted, but for the most part it seems as if they had won. Tier Harribel is frozen within Captain Tōshirō Hitsugaya's Hyōten Hyakkasō and Baraggan Luisenbarn seems to have been destroyed by Captain Suì-Fēng's Bankai.

Suì-Fēng can barely keep herself airborne, Lieutenant Marechiyo Ōmaeda tries to support her, but she angrily declines. A bit disgruntled, Ōmaeda says his captain should humbly accept her subordinate's kindness, but dares not repeat it to Suì-Fēng's ears.

He says Baraggan was frightening and asks her if she doesn't agree, but she says it's all in the past now, nursing her severed arm.
