See, most of the time it was Sukuna turning Yuuji silent after doing something or saying something so shocking or frustrating but this time? Yuuji was so done with everything that he snapped and finally shut that Cursed spirit up for once in his 1000 plus years.
To be entirely fair, he couldn't remember what had happened before he broke but break he did at simple words.
"You're always so wound up, brat."
The literal audacity he had.
"Yeah, I wonder why? Maybe it's from the fact that I had to see my friends almost die in front of me and made me so desperate I ate a fucking 1000-year-old finger a few hours after the man who raised me died? Or maybe it's then being unable to mourn my grandfather after that because it turns out that eat that finger made me suddenly get put on death row because of it inadvertently reviving a sadistic bastard that for god knows why he wants to kill all of humanity instead of dealing with his emotions like a responsible person."
Sukuna's eyebrow twitched and lifted a finger, Yuuji getting sliced into pieces once again. When his vessel revived however it was clear he wasn't done talking.
"Maybe- you fucker- just maybe I'm so wound up because I have to risk my life, even more, each day with my new friends because these shitty cursed spirits tend towards violence? Maybe it's because no matter how much I try to get stronger and protect the people I care about, I'm still so fucking weak that I have to see them die and getting irreversibly hurt. Maybe it's cause my sensei got sealed and I was too weak to rescue him and the only fucker that could help me, is a pissy 1000 plus-year-old cursed spirit that thinks the world revolves around him and has fun by scaring a teenager by killing hundreds of people just for the hell of it. And maybe I'm wound up because a bunch of old fucks thinks that killing a teenager is the best way to go about something they fear. After all, god forbid they try to train that teenager. Oh and that death sentence that was at least a year or so away is probably going to happen next week because the only person who could stop it IS FUCKING SEALED!"
"Not to mention I'm a god damn teenager! I should be allowed to live out the rest of my high school years because I'm being obedient and I'm not even gonna fight the whole death sentence! But no, I have to deal with shitty other sorcerers that tell me I'm an abomination even though I did it to save my friends! And I didn't know shit about this whole jujutsu cursed spirit shit, how was I supposed to know I was going to be stuck with an asshole in my head! So yeah. Maybe I am a little wound up but it's for good fucking reasons."
Sukuna just stared at him. For a while. And to be entirely honest, Yuuji didn't know where that whole outburst came from either. It's not like the cursed spirit would care or do anything but it was pretty nice to be able to get it all out. Complaining to his friends would only make them sad and guilty that they couldn't do anything to help him. Sukuna very well could help him and he didn't know the word guilt so he was free to bitch at him for as much as he was allowed.
"You're going to slice me up again aren't you."
"Yes."
"That's fair."
