Jujutsu kaisen x oc (reader) yandere

Hana has spent her entire life pretending not to see monsters.

Curses lurk in every dark corner of the world, feeding on fear and misery, and Hana has seen them since childhood. After witnessing one slaughter her parents, she learns quickly that survival means staying quiet, staying invisible, and never drawing attention to herself.

But loneliness has a way of attracting dangerous things.

When a strange little curse begins following her home, Hana expects another nightmare. Instead, she finds something she has never truly had before: companionship. The creature, whom she names Nox, becomes fiercely attached to her, guarding her with unsettling devotion.

Then one night at school, Hana witnesses the impossible.

A boy named Yuji Itadori fighting curses alongside mysterious sorcerers who can actually kill them.

For the first time in her life, Hana realizes she is not alone.

Unfortunately for her, she has now been noticed.

And in the world of jujutsu sorcerers, curses, and monsters wearing human faces... being seen can be far more dangerous than being invisible.
