is bleach episode 120 filler?

In the air above Karakura Town, a fatigued 6th Division Lieutenant Renji Abarai pants as he wields his Bankai, Hihiō Zabimaru, and faces off against a smirking Yylfordt Granz, whose Zanpakutō is dripping with Renji's blood. Simultaneously, an exhausted 10th Division Captain Tōshirō Hitsugaya bleeds from a wound on his forehead and faces down an impassive Shawlong Koufang with his own Bankai, Daiguren Hyōrinmaru.
