Curses across Tokyo start disappearing without a trace - no lingering cursed energy, no signature, nothing. The only lead is this mysterious girl: Aya, a sorcerer who gives off zero cursed energy... until she moves.
She's also the one thing jujutsu society hasn't had in years: a sorcerer second only to Gojo Satoru. Strong enough to stand near him without being crushed by the gap - and useful enough to the higher-ups that they finally start acting like the world can't revolve around Gojo forever.
Gojo hates the timing, hates the politics, and hates the fact that even his Six Eyes can't read her. The students warm up to Aya fast - she's kind, calm, and fiercely protective of their youth - but Gojo keeps his guard up, convinced she's here to watch, report, and enforce the elders' will. Except Aya keeps stepping into danger meant for kids, keeps taking on burdens no one should have to carry, and keeps speaking with the quiet weight of someone who knows what it costs to be "the strongest."
As missions intensify and pressure builds outside the school, Aya's presence starts cracking everything the higher-ups think they control - including Gojo. Because the more he watches her, the more he realizes the real threat isn't what she can do.
It's why the jujutsu world needed someone like her at all.
