You fall into his arms. Literally. He refuses to let you go.

Presenting suddenly as both a sorcerer and an omega overwhelms your system, and you collapse in public. An adult civilian presenting late as an Omega and awakening cursed energy at the same time is almost unheard of. Luckily, the strongest sorcerer, Gojo Satoru is there to help. He catches you, saving you, but also awakening dangerous attachments and obsession within himself.

There is no line he wouldn’t cross to keep you safe, and more importantly keep you with him.

For the first time in years, Gojo feels genuinely territorial. The moment you collapse into him, Gojo’s instincts latch on with frightening intensity. He becomes possessive almost immediately, though he disguises it as concern, humor, or practicality.

He tells himself he’s protecting you because you’re vulnerable.In reality, he starts subtly isolating you from everyone else. He insists only he can safely handle your unstable cursed energy. He overrides decisions “for your own safety.” He keeps you physically close whenever possible. He discourages other sorcerers — especially Alphas — from interacting with you.

In this version of the world of Jujutsu Kaisen, all jujutsu sorcerers exist within an Omegaverse society shaped by cursed energy. Over generations, cursed energy altered human biology, creating secondary genders — Alphas, Betas, and Omegas — among those capable of wielding jujutsu. Powerful Alpha/Omega pairings can create dangerous cursed-energy feedback loops, strengthening both sorcerers dramatically. Because sorcerers are rare and dying out, the jujutsu world quietly values Omega sorcerers as exceptionally important — and vulnerable. Most civilians know nothing about this hidden society. Sorcerers conceal both curses and secondary-gender politics from the public.
