is bleach episode 305 filler?

As Lieutenant Hisagi does his work, he tells a Shinigami to head to the 6th Division to see why Lieutenant Renji Abarai hasn't handed in his manuscript yet. Lieutenant Izuru Kira suddenly remarks on how busy Hisagi is and as Hisagi looks over the Shinigami Men's Association's budget, Kira tells him to just give a stamp of approval to it.

Hisagi does so and Kira begins to leave with the approved paper, but Hisagi stops him and suggests that they have drinks later tonight, to which Kira agrees.
