is jujutsu kaisen episode 33 filler?

Gojo enters the underground and faces a gauntlet. Cursed spirits surround him with civilians as shields, limiting his options.

Despite the handicap, Gojo fights with surgical precision — clearing enemies while keeping casualties minimal. He activates Unlimited Void in a crowded space, threading the domain to paralyze curses while leaving civilians at the edge with survivable exposure.

Then Kenjaku reveals Geto's face, and Gojo freezes for 0.2 seconds. The Prison Realm activates.

The strongest sorcerer is sealed.
