is bleach episode 102 filler?

Outside the gate to the Shinigami Research and Development Institute, six Shinigami stand guard and discuss how they are unexpectedly guarding the facility due to the number of dangerous tools and bizarre items contained within before being startled upon seeing Jin Kariya approaching them in the distance. When one of the Shinigami realizes Kariya is a Ryoka, he and the others draw their Zanpakutō and rush to surround Kariya, who comments on what a nice day it is and grins maliciously as he looks around at them.
