After the Night Parade of One Hundred Demons, the people at the technical college discover a mysterious shop and its strange owner have appeared out of nowhere inside the school's barrier.
The shop sells all kinds of bizarre things.
There are oddly shaped ornaments, glasses that double your ability to make sarcastic remarks when you put them on, rabbit feet that increase your luck...
Even the most ordinary items can somehow restore cursed energy, and the food has an effect comparable to the Reverse Cursed Technique.
The most mysterious of all is the shopkeeper, who calls herself Aurelia.
Even Gojo Satoru, the college's strongest special-grade jujutsu sorcerer, can't see through her power.
Nobody knows where she came from or what she wants.
Only Aurelia herself knows:
She's just an unlucky transmigrator who lost her memories and is bound to a System.
Some details are my own, and any out-of-character portrayals are on me.
