The Youth of the Future Strongest

Tokyo Jujutsu High School, 2005. First year student Satoru Gojo was told a new transfer student has arrived to start later within the school year to learn curses. Unfortunately, she's an outsider to the whole curse spirits and using curses to exorcise but has a powerful curse technique that was never noticed by other sorcerers until now? Another weird detail about this Su character has him wondering if someone was pulling a prank on him. There's no way she's a modern-day shinobi! Who is this new student and will he even bother considering this girl to be his equal in the future? Only time will tell.

This will be a one-shot story starting with Satoru and Su's relationship.
