is bleach episode 154 filler?

Within his area in Las Noches, Gantenbainne Mosqueda runs forward and throws an energy-infused punch at Yasutora Sado, who blocks it with his Fullbring, Brazo Derecha de Gigante, as energy surges out from Gantenbainne, who smirks before overpowering Sado's defense and sending him flying backward across the room. After landing on his feet, Sado looks back to see a pit behind him, to his surprise, prior to Gantenbainne questioning where he is looking and rushing toward him and hitting Sado hard in the midsection with another energy-infused punch.
