is bleach episode 76 filler?

Having been welcomed to the Bount Mansion by Jin Kariya as he stands on the steps before them in the main hall, Ichigo Kurosaki stands with Rukia Kuchiki, Ririn, Kurōdo, and Noba as he inquires if Kariya is the leader of the Bount and declares that they accepted the latter's invitation to come here, leading Kariya to grin as he exerts his red Reiatsu, which unnerves Rukia and confirms Ichigo's suspicions. When Kariya identifies himself and greets him by name, Ichigo questions how Kariya knows his name.
