is bleach episode 239 filler?

In the Forest of Menos, as the bodies of several Gillians dissipate, Muramasa walks over the cracked ground. Looking at Muramasa from the top of a nearby tree, an Adjuchas-class Hollow leaps at Muramasa and attempts to attack him.

Manifesting his sword, Muramasa slashes the Adjuchas. As the Adjuchas is cut into pieces and dissipates, Muramasa notes this is not good enough and coughs.

When the area around him is bathed in pink light, Muramasa turns around to see a humanoid Hollow glowing with pink Reiatsu. As Muramasa states this Hollow is the one, a small shockwave radiates outward from the Hollow.

Meanwhile, 5th Division Lieutenant Momo Hinamori leaps through the trees.
