is bleach episode 81 filler?

At Karakura Station in Karakura Town, a man exits his car with an umbrella in a parking lot while it rains at nighttime and informs someone he is calling that he has arrived. As he informs the other individual that he ate dinner earlier, the man hears a screeching noise and is startled when two Bitto confront him, causing him to flail his umbrella at them in a panicked attempt to keep them back.

Suddenly, a third Bitto jams its stinger into the back of the man's neck.
