[Jujutsu Kaisen/Detective Conan] Divine Justice Crashes Down on a Rotten Tangerine

Inspired by an idea from the Lofter author Columba (please, I beg you, leave me a comment).

Also known as "After Heavenly Justice Crushed the Rotten Oranges of the Jujutsu World, My Disaster-Class Classmate Helped Me Fight Crime and Corruption."

After graduating from the police academy, Rei Furuya accepted an invitation to join the Public Security Bureau.

But he never expected that his first assignment from his superiors would be to go undercover as a student at a religious technical college?!

Rei Furuya: Eyes trembling in shock.

Not that he couldn't do it, but what was he supposed to do undercover there?? Were those students criminals or something??

After a long back-and-forth with the higher-ups, the administrator finally appeared in person, pinched the bridge of his nose, sighed, took a classified document from a drawer, and laid it on the desk. Then he spoke frankly: "Furuya, it's not that Public Security doesn't want to send you undercover into the Black Organization. It's just that sending someone with your qualifications there would be a waste. Besides, you know that Japan's missing-person numbers remain alarmingly high, and that they're connected to various paranormal incidents. For this assignment, Public Security wants you to investigate the many anomalies at Tokyo Metropolitan Jujutsu Technical High School."

Rei Furuya frowned. "Then why me? Isn't there a specialized agency?"

The administrator slid the file across the desk, his gaze wandering. "They might not meet the requirements to get into that school, and the people who do qualify look too old. Anyway, you're the only suitable person in Public Security."

Rei Furuya: ???

Theme: Double the justice, speed-running the forces of evil.
