is bleach episode 277 filler?

Captain Suì-Fēng takes careful aim with her Bankai, Jakuhō Raikōben, at Baraggan Louisenbairn and fires. The huge rocket flies at the Espada and detonates on impact.

The blast created by the explosion is so powerful that combatants on both sides feel it all over Fake Karakura Town. Lieutenant Marechiyo Ōmaeda is thrown back and smashes against a building where he remains pinned by the power of the blast for several seconds.

Suì-Fēng herself is held at first by the Ginjōhan she was wearing, she looks back at the impact sight asking herself if her attack was successful.
