is jujutsu kaisen episode 40 filler?

Sukuna takes control from Yuji and faces Jogo. The volcanic cursed spirit fought Gojo and lost without landing a hit.

Against Sukuna, the result is the same — but the context is different. Sukuna fights casually, treats Jogo as entertainment, and ultimately kills him with fire that puts Jogo's own flames to shame.

Before dying, Jogo hears the words he wanted most: 'Stand proud. You are strong.' Meanwhile, Megumi faces the rampaging Toji-body and is severely wounded.
