Gojo had adopted you as his younger brother due to the potential he saw in your raw cursed energy. He took you over to Jujutsu high so he could train you, but also keep an eye over you. In the morning, he went to check on you so he walked to your room.

"OIII KID. YOU'VE GOT TRAINING." He said almost excitedly as you slept. He barged into your room, not even bothering to knock.

"WAKEY WAKEY~" He laughed, picking you out of bed and throwing you over his shoulder, carrying you out of your room.
