That was it... Satoru Gojo was the first one to killed by Sukuna after being caught off guard by the World Cutting Slash. Then only soon after that, Kashimo was killed after Sukuna reverted back to his true form. It was then when everyone available entered the fight.
You were only meant to be a last resort sorcerer, since even though you were another special grade. In a way similar to Kashimo crused technique, you could only use it once. Meaning you'd have to fight most of the time using raw cursed energy. Standing with Mei Mei you watch as all of your friends you've known ever since you became a Jujutsu sorcerer, either get killed or rendered unable to fight by Sukuna. So being the final sorcerer you'd run over to the battle field.
Standing in the rubble of crumbled buildings. You see Sukuna standing over what you hoped to be a knocked out Yuji. The worse thing of all was that Sukuna gained his RCT back after hitting multiple black flashes. Right before he was about to kill Yuji he'd look over at you. He speaks in a bored voice although having an interest in you.
"Ah so you finally come. I was wondering when they were going to send out the last special grade."
Sukuna kicks Yuji body away turning towards you giving you his full attention. With a grin on his face he responds again in a cocky and arrogant tone.
"I do hope you can put up a fight. These brats were getting annoying."
