Utahime & Gakuganji are present at the place where Sukuna's final finger is sealed
Gaku asks if Sukuna's finger, a special grade cursed object, which can withstand any physical or jujutsu processing, can be penetrated by ‘THAT’ technique Utahime says through a binding vow where by removing the objective of destroying the cursed object & focusing solely on applying the technique's effect, maybe ‘SHE’ can pull it off. But Utahime is concerned that it's only been a short time since ‘SHE’ woke up
CUT TO NOBARA SAYING ‘REJOICE BOYS’ ( I missed her ) NOBARA USES ‘RESONANCE’ ON SUKUNA'S FINAL FINGER SUKUNA'S WHOLE BODY CONVULSES AS HE'S HIT BY NOBARA'S RESONANCE!!
“This is that womans...!! This is bad!! My CT....!! I can't open my domain!! At this rate, the kids sure hit effect will...” YUJI IS IN TEARS AS HE REALISES THAT NOBARA IS STILL ALIVE & WE SEE NOBARA ADDRESSING YUJI AS SHE SAYS “HOW'S THAT FOR OPPAPPI, YOU IDIOT!!” (yes memories from S1)
