BSD X JJK
I just started watching JJK yesterday and after the Gojo Dazai similarities, I got these ideas for crossovers/aus. I don't know the JJk characters that well yet, but here you all go.
Jujustsu High = the people who work/attend the school.
ADA = the detectives or people who are affiliated with the ADA (like Katai).
IDEA ONE -
Complete Swap
ADA is Jujutsu High
Jujustu High is ADA
IDEA TWO -
Partial Swap (Curses exist in both universes w/ physical forms)
ADA is Jujutsu High but they teach people to use their abilities to fight curses.
Jujutsu High is ADA and solves crimes caused by curses w/ their reverse curse techniques
IDEA THREE -
Partial Swap No. 2 (Curses exist in only one universe, but only as energy, no physical form)
ADA is Jujutsu High but they teach people to train their abilities so they don’t cause trouble.
Jujutsu High is ADA and uses energy from ancient curses to solve crimes. (reverse curse techniques are like their abilities)
IDEA FOUR -
No JJK characters, only the setting.
ADA is Jujutsu High but they’re a curse detective agency (kind of like Ghost Busters) who disguise themselves as paranormal detectives. People call them if they think there’s a “ghost” Usually it’s a curse and then they exterminate it.
(ALT: Maybe JJK characters are more employees)
IDEA FIVE -
Silly High School Sports anime vibes
ADA is the Yokohama Jujutsu High Campus and they’re always competing with each other. Ofc Dazai and Gojo are BFFs, and when they’re together Kunikida and Nanami have to get drunk to stand it.
