is bleach episode 168 filler?

At the Tenth Division barracks in the Seireitei, Lieutenant Rangiku Matsumoto excitedly leans over the desk of her captain, Tōshirō Hitsugaya, and asks him if he heard that the Third Division is getting a new captain, prompting an annoyed Hitsugaya to remind her that he has already heard because he is a captain and continue filling out documents as he clarifies that the official announcement will be made at the captains meeting tomorrow. With Rangiku wondering when 3rd Division Lieutenant Izuru Kira learned to perform Bankai, Hitsugaya reveals that he is not the new captain.
