Jujutsu Kaisen Otome: Emptiness

※ The heroine and her world are from the author's original work, which has not yet been published. She has a name, transmigration, and a complicated background. Readers are welcome to piece things together. ※ This is my take on the heroine. She's very assertive, strong, and cool. Imagine a toned-down Gojo Satoru (maybe?). Anyway, the author is having a great time swooning over her (...). ※ No specific pairing for now: all → (←?) you → ? ※ The characters may be out of character. This is adapted from the original, with the viewpoint and narration shifting whenever. Please excuse the poor writing. ※ Synopsis: You were just going to take an ordinary nap, so why did you open your eyes to find yourself in the sky? And in the middle of a fall, no less. Don't panic. You've seen all kinds of storms. Surely there's no reason to be scared. You're not scared, but you've never been in a situation like this before. Still, isn't this exactly what you wished for? Hm? What's that pitch-black thing below, like a barrier? Has technology advanced that much? Fushiguro Megumi really wants to hit someone, namely that irresponsible teacher of his. If he hadn't left a special-grade cursed object somewhere an ordinary person could easily reach it, this whole mess wouldn't have happened. Now he's trying to escape with an ordinary person who's unbelievably athletic but refuses to listen when told to run. With curses in front and the Grim Reaper behind, they're at the end of their rope... Wait! What's that!? He thinks he sees some unidentified object plummeting at high speed! And it's heading... right here!? Is today really the day he's going to die? Message: What sparks might fly when an unconventional heroine with a vivid personality and absurd strength enters the picture?
