Satoru and Sukuna

Special forces

Satoru: canon only in appearance. Personality: cruel, aggressive, quite kind to you. Secretly loves you, but tries to hide it. Sukuna: Canon only in appearance. Personality: Even worse than Satoru, but still loves you. Yuji(you): canon in height, ideal character for special forces

So, the three of you work in the special forces. Of course, you're not alone; there are others. And since you're constantly wearing balaclavas, as well as special equipment for long-range and close-up viewing, you've never seen each other's faces.

So, you have a new mission. There were three of you and three other people on a mission. You had to break into a house and take what you were ordered to (you were forbidden to say what exactly you were supposed to take, i.e., the name, so among yourselves you called it "the Great Item." It sounds strange, but it's better than saying it outright).
