I’m putting together an AU right now!
The core idea is that the world originally had way, WAY more cursed energy than in the original series. So when Tengen created her barriers, the other jujutsu communities around the globe kept developing. Now we’ve got: Japan’s clans (obviously), the Jujutsu European Church, the American Cursed Guilds, the African Commune of Sorcerers, and independent sorcerers scattered everywhere. The European Church’s whole thing is superior and much more common mastery of RCT (due to the Ultimate Binding Vow of Christ), the African Commune specializes in creating cursed tools, and the American Guilds are somewhat about shikigami mastery (because of spiritual awareness of Native Americans).
About the organizations: I have the International Jujutsu Headquarters, which rose to power after the Last War (a huge world event that happened at the end of the 1980s) and they’re now trying to improve jujutsu regulations and make the world generally a better place. The clash between the Old Guard (Three Big Clans) and the Progressivists is also a major part of the story. I also made a point of separating government-affiliated jujutsu organizations from the naturally evolved ones. Like Japan has its own Ministry of Jujutsu Affairs that practically operates independently from Gojo, Kamo and Zen'in; America has Counter-Jujutsu Rapid Response Unit that reports to the Department of Homeland Security, etc. I did this because I just love it when a fictional world has a ton of factions with different dynamics and potential for conflict.
Another consequence of the Last War and a major difference from the original series is that non-sorcerers are partially aware of jujutsu. But I feel like, in a situation like that, they’d just view all sorcerers as government agents—like police or firefighters—and that awareness wouldn’t breed any respect. So Geto would still end up becoming a curse user in this AU.
I also want to place a strong emphasis on the Timeline itself as a core element of the work. What I mean is filling it with interesting events so that the world feels more fleshed out and developed from a lore perspective. Detailing and elaborating on events from Antiquity to the 20th and early 21st centuries. Because I didn't like the fact that Gege didn't give us Heian Era flashbacks.
If you wanna know more about the project, I have an entire wiki dedicated to it that is currently in development: https://jujutsu-kaisen-absolute.fandom.com/wiki/Jujutsu_Kaisen_Absolute_Wiki
I wanna her your all thoughts on it in general and also some CT ideas for different regions.
Also, if someone want to work with me (like, draw some manga panels or contribute to characters creation or smth like that) than pls dm me!
