is bleach episode 341 filler?

Having gained a pseudo form of his former powers, Ichigo begins to fight against Ōko Yushima. From the sidelines, Kon wants to help Ichigo save Nozomi, so Rukia Kuchiki, agreeing, grabs him and, along with Lieutenant Renji Abarai, Yasutora Sado, and Uryū Ishida, they attack Yushima.

Despite being attacked by all five of them, Yushima, deflecting their attacks, further wounds Renji and Sado, forcing Uryū and Rukia to grab them and fall back. Getting an idea, Ichigo, moving to Yushima, grabs his Zanpakutō, preventing him from using its powers.

Donning his Hollow mask, Ichigo unleashes a massive, point-blank Getsuga Tenshō. After the dust clears, Yushima is severely wounded from the attack.
