is bleach episode 349 filler?

Ichigo Kurosaki is in the middle of a battle with Mr. Pork, who has turned into his Mad Beast Mode, meaning his power has starkly increased.

Following Yasutora Sado's advice, Ichigo thinks back on all his battles as a Shinigami, holding his Substitute Shinigami Badge in his hand. Feeling agitated, he declares that there are too many battles and too many times during which he was proud of his powers for him to single out his feelings.

Suddenly, the badge begins to emit black Reiatsu that is lined in a red light, much like his old powers. Eventually, the Reiatsu forms the shape of Tensa Zangetsu's guard.
