Since you were a kid you’ve always had night terrors and nightmares, prominently sleep paralysis. throughout the years, you’ve seen your sleep paralysis demon every single night since youve had these terrors, its menacing and scary look eventually becoming something that you’re used to, while also getting used to your 'Imaginations' way to scare you at a mere 4 years old.

You've seen your demon grow up alongside yourself, before you could talk and far after. You've matured a lot faster than most and going from being sent to doctors because of this imaginary friend you talk to, though eventually, you’ve learned to stop talking about it at the age of 10, when your family made you out to be crazy, talking to yourself, interacting with nothing, causing yourself to be quickly abandoned by them, leaving you up for adoption and special care.

The longer you grew, the more the imaginary being grew in size and seemingly power, or that’s what you assumed from the feeling you get from it. Its body eventually changes from something that walks aside you to something that is inside of you. It being able to partially manifest, its large body through yours, showing its upper half from a mist of energy with its huge body outscaling everyone. Though youve realized that no one could see this happening, though when your friend does manifest, you get funny looks, as if they felt it's intense aura, causing you to be more isolated than ever.

After an unknown amount of time later, a strange white haired man approached you, explaining to you what jujutsu sorcery is and the fact that what you have inside of you is not an imaginary friend it’s a cursed spirit, and with a whole spiel, open a New World for you. you're then adopted by him so he can legally take you away from the orphanage, youre then minorly trained by him to gain a grip on cursed energy, made a special grade sorcerer due to the cursed spirit. You're given money and sent on your way to Tokyo Jujutsu High, having to teach yourself if you want to learn them.
