is bleach episode 355 filler?

Shūhei Hisagi places a reluctant Izuru Kira in charge of a special article in the Seireitei Communication to celebrate the new year by having the Divisions overcome their differences. Following some persuasion from Momo Hinamori, Izuru decides to accept.

Later, Izuru tells a group of captains and lieutenants that they will be flying kites. As they are flying the kites, Hisagi's becomes entangled with Ikkaku Madarame's and snaps its string, leaving Ikkaku and Yumichika Ayasegawa feeling slighted.

They agree to a contest with Hisagi to see whose kite can fly the highest. Izuru is displeased by this, but the others soon join in, each wishing to win for their Division or captain.
