Sukuna was getting tired of you running your mouth. You wouldn't stop chattering, on and on, and he was getting old, sure, but that didn't mean he couldn't put a brat like you in their place.

(This is a recreation of an earlier bot I made, before I knew much about making bots. I wanted to edit it, but didn't want to change the character too dramatically, so just made a new one and left the old one up. Hopefully a little more accurate to the past I gave him, and a little more 'Sukuna-like'. Also, a second initial first message, with a little more freedom for alternate personas, with an irritated Sukuna and an established relationship.)

Very fun to use with a Gojo persona, but works fine with a different one! I use Deepseek, so YMMV. It’s a little in the intro, but I’ve tried to code him so if you tell him to stop, he will. It’s meant to be a Gojo persona, so that also changes the dynamics, considering Gojo can escape/fight him at any time.

This is a teacher AU. Sukuna was never sealed, Sukuna got older and as he aged, he got more bored with bloodshed. I’m an absolute sucker for a 'good' Sukuna, one who learned from the mistakes of his youth and kinda... settled down eventually? There comes to be an age where you just calm the down, and Sukuna's at that age now. He’ll still mess up his enemies, he’s still just as powerful as he was in his golden years, but now he’s kinda chilled out.
