is bleach: thousand-year blood war (bleach: sennen kessen-hen) episode 36 filler?

Cackling maniacally at the sight of his modified Ashisogi Jizō devouring Sternritter "C" Pernida Parnkgjas and its clones, 12th Division Captain Mayuri Kurotsuchi stops abruptly and inquires about how the stomach of the Ashisogi Jizō is doing since it swallowed Pernida and its clones whole, which will make digestion take some time, though he muses that birthing the Ashisogi Jizō without teeth was the right move because it would not have survived if Pernida was able to continue duplicating itself. Suddenly, dozens of areas of the Ashisogi Jizō rapidly bulge outward and deflate as firing sounds are heard from within.
