is jujutsu kaisen episode 41 filler?

Megumi, near death after the Toji encounter, is attacked by Shigemo. Desperate, Megumi heads toward Dogenzaka crossing and attempts to summon Mahoraga — the strongest shikigami of the Ten Shadows, which no user has ever tamed.

The summon is a suicide move. Sukuna, sensing the summon, intervenes — not to save Megumi, but because Mahoraga interests him.

Sukuna fights and destroys Mahoraga using his fire technique, but the collateral damage devastates a section of Shibuya.
