is bleach episode 75 filler?

At night in Karakura Town, Uryū Ishida sits on the bed in Yoshino Sōma's apartment across from Yoshino herself, who stares back at him from a table near the wall and smiles as she assures him he does not need to watch her since she will not leave without telling him. Suddenly, the lights in the room turn off, prompting Uryū and Yoshino to stand up in alarm before the door is destroyed, which leaves Uryū to demand to know who is there while Gō Koga enters.
