is bleach: thousand-year blood war (bleach: sennen kessen-hen) episode 34 filler?

In Wahrwelt, 6th Division Lieutenant Renji Abarai collapses after being shot through the chest by a Heilig Pfeil from Sternritter "A" Uryū Ishida, who deactivates his Quincy: Vollständig and walks over to Renji as blood pools underneath his body. With Uryū standing solemnly over Renji, Sternritter "X" Lille Barro eyes him from his perch on a different branch and holsters his Spirit Weapon, Diagramm, before watching the remaining captains and lieutenants regroup on the streets below and continue running toward the central palace.
