is bleach episode 176 filler?

Rukia Kuchiki's opponent, Jinnai Dōko, asks if they wouldn't mind just handing Rurichiyo Kasumiōji over, however Rukia refuses and attacks him. Rukia tries to capture him, but he easily breaks free of her icy attack.

Jinnai reveals that the unique blades the assassins are using are called Bakkōtō, swords that consume the user's spiritual energy to increase their strength. Jinnai eats his Bakkōtō to increase his power and quickly overpowers Rukia.

With Rukia down, Kenryū steps forward and releases his Zanpakutō. Kenryū successfully stalls Jinnai and he instructs Enryū to take Rurichiyo and run.

Jinnai quickly breaks free of Kenryū's trap and chases after Rurichiyo.
