is bleach episode 56 filler?

Walking down one of the streets of the Seireitei while humming to himself, 11th Division 5th Seat Yumichika Ayasegawa hums to himself as he reaches an intersection and turns to the right upon deducing that his captain, Kenpachi Zaraki, is likely this way. Up ahead, Kenpachi sits on the destroyed bridge with his Zanpakutō embedded in the ground in front of him as he sighs, and when Yumichika spots him from afar and inquires if he won, Kenpachi reveals that 7th Division Captain Sajin Komamura ran off in search of Captain-Commander Genryūsai Shigekuni Yamamoto.
