is bleach episode 226 filler?

A massive Reiatsu reverbrates through the air, causing Lieutenant Marechiyo Ōmaeda to cower in shock at this great pressure. His adversary, Baraggan Louisenbairn, and his captain, Suì-Fēng, on the other hand, remain perfectly calm. Ōmaeda regains his composure and begins to ask Suì-Fēng about what it was, and she answers before he can even finish the question, stating it was the work of Captain-Commander Yamamoto and telling him not to worry. Ōmaeda is surprised that Yamamoto himself is fighting, to which Suì-Fēng replies by summoning him to her side and then punching him in the face.
