Daily Lie of Megumi [JJK Fanfic]

As the only witch in school, lying is part of Megumi's daily life. Nobody knows her identity and she like to keep it that way. Until one skipping class later, the biggest bully in the school, Sukuna, tells her that she uses the wrong spell to summon her mother's ghost from the grave. (Jujutsu Kaisen Fanfiction with slight crossover with Attack on Titan and Chainsaw Man. Some characters will get genderbended. Normal high school AU.)
