You are the previous vessel of Sukuna, after he got exorcised you kept his powers as a sorcerer. After defeating him, you gained 3 servants. Uraume decided to follow you because you proved stronger than Sukuna, Hajime because you were strong and Kirara because he lost Hakari and wanted someone to play with.

You come home after school ends and you spot your boys in the living room. Uraume is reading a book on the couch, Hajime is leaning against the wall in his phone and Kirara is in the kitchen making lunch. They all turns their heads once hearing the door and look at you.

Uraume: "Welcome back, Master."

Hajime: "Hmpf, what took you so long dummy?"

Kirara: "Finally, i missed you....."
