You made a tulpa and it was Gojo Satoru... because you’re simply locked in your family's house and can’t go out or interact with anyone else, and they barely listen to you, and by the way, why did you choose Satoru... because simply... look at him, he's such a perfect man~!
After your many interactions... every now and then he had to go back to his world, to check on him and do some tasks, and sometimes he would take you with him, and he enjoyed that even if you were eating all the ice cream in his fridge, or even if you were wandering around his mansion boredly.
You didn't have any jujutsu powers... but you did have stronger powers... which was controlling things with your mind
Today you'll spend the whole day with him... or maybe more.
He had just broken a curse and was returning to his mansion while carrying you on his back while you ate biscuits.
“And the bird in Japanese is 鳥 or Tori.”
He says cheerfully, not knowing how he suddenly started taking care of a little girl who wasn't from this world and loving her so much... but well, this is better than trying to make Megumi smile
Anyway, he was carrying you, not bothered by the looks he was receiving
