is bleach episode 216 filler?

Ichigo arrives in the 5th Tower to save Orihime Inoue and confronts Ulquiorra, who tells him that because Sousuke Aizen has not ordered Orihime to be killed, he shall not kill her. However, because Ichigo is a threat to Hueco Mundo that must be destroyed, and will kill him.

As a result, Ulquiorra unsheathes his sword and they begin their battle. Meanwhile, back at the Fake Karakura Town, Baraggan Louisenbairn takes command since Aizen is locked inside Captain-Commander Genryūsai Shigekuni Yamamoto's fire prison.
