is bleach episode 209 filler?

In the Seireitei, Captain Shinji Hirako and his lieutenant Sousuke Aizen greet Captain Kisuke Urahara, Lieutenant Hiyori Sarugaki, and Mayuri Kurotsuchi. After some brief distractions, Urahara learns that various souls in the Rukongai have been disappearing since the last month.

Oddly enough, it turns out that only their bodies have disappeared and not their clothes; both should vanish if the person has died. Shinji states that this analysis is what he got from Captain Retsu Unohana and mentions that the Ninth Division have been sent out and are currently doing an investigation on the matter.
