is bleach episode 359 filler?

Isshin and Urahara walk down the street during the night in silence. Isshin carries a blue, glowing sword.

Ichigo and Kūgo Ginjō catch their breath. Kūgo informs Ichigo that they should be safe here for a while and that he kept the place in the event that Tsukishima found all of their safe houses.

Not even Riruka or Kutsuzawa know of the hideout. Ichigo frustratingly questions why this is happening.

He grabs Kūgo by his collar, claiming it's his fault for dragging him into the mess. Kūgo agrees with him and apologizes.

Ichigo lets go of him and says that he knows they were only trying to help and that it's not their fault. Kūgo tells him that it's nobody's fault and not to blame himself.
