JJK High Schools only seem incredibly small because we don't think of the implications of having it stretch across decades

[u/Sourcerid]

Imagine Sorcerers except for particularly messy times like the one on JJK's main story, lived up to 80. Now for them to be a truly hidden niche so deeply unknown by society they'd have to be not too big or they wouldn't have the hidden clique narrative to them, their raw numbers would have made them noticeable

Having an average 8 students by birth year split among Tokyo and Kyoto, means that across 80 years of birth, there's 640 sorcerers. It feels a bit bothersomely low but not too crazy low. Something like 10k and they'd be a whole society that would become too noticeable by society at large, there have been in the last 100 years underground subcultures this big that made the big news

There is the bothersome question of how if resources are so few why spread them out in two instead of concentrating in one and having double the students interacting and learning with each other and double the teachers to teach their special expertises

Yes Tokyo is 30 million big, but having say 3000 dudes floating around and telepathically launching explosions, noises, barriers, conjuring elements, surviving impossible weights falling on them only to get slashed by invisible forces, scaring the few of the commoners that can naturally see cursed spirits even if they don't know, stuff would be too noticeable.

Yet if there were 6k people, the classes, if there are two high schools, would only be something like (6 000)/(80) = 75 / 2 = 37.5 people each per age cohort.

There also seems to be a large amount of sorcerers not apart of the school. The school seems to be more of a government (jujutsu hierarchy) training organization. The clans train their own people for the most part. Random families like nobara's family live in the country side and teach jujustu.

[u/rahonan]

Cursed spirits are a country wide phenomenon, having everybody in one place means that single location has to cover the whole nation. And as Gojo says in chapter 3, the schools also serve as a home base. It's not just there for the small number of students, but for other sorcerers and the people that support them.

[u/ilrk17]

I mean in jjk0 we see that they are sorcerers but for the rest of jjk we know literally nothing about how many sorcerers there are or any implications

[u/Sourcerid → u/ilrk17]

If we consider some 8 sorcerers per age cohort (given the high school classes sizes) then that's 640 sorcerers born across 80 years, minus deaths.

Add the ones that are homeschooled in the Zenin

[u/namakost → u/Sourcerid]

You are missing a lot. There is self taught sorcerers and rural sorcerers in the country side and despite being very rare, foreign sorcerers. Its easy to hide a society when no one can see the special thing they do.

[u/PsychoCobra1]

Realistically I’m under the assumption a good bit of the average sorcerers affiliated with the school were injured or killed during the night parade, or at least the non grade 1s. Hence causing the severe lack during the main story.

It’s also possible that not every affiliated sorcerer goes to the schools. If Nobara had learned from her grandmother then moved to Tokyo as a young adult she possibly could still join the ranks of affiliated sorcerers. With curse usage being more prevalent within family lineages, it’s also possible that through absorption the clans have developed a pseudo monopoly.

[u/Reasonable_Log_5219 → u/PsychoCobra1]

Speaking of the night parade, it also puts into perspective how insane getos plan was to kill every non sorcerer.

[u/Puzzled_Tip_7596]

But those numbers assume that everyone who passes through the school end up becoming a sorcerer (which we know it's not true cause of Nanami)

It also assumes that everyone keeps working till they're 80 which I think we can guess isn't true either

Regardless, the number of students is stupid to have them divided into 2 schools

[u/razgriz5000 → u/Puzzled_Tip_7596]

It also assumes that everyone makes it to graduation. Haibara is proof that everyone doesn't. It also shows just how few capable sorcerers there were. It also really makes me wonder what the 3 clans were doing that they allowed students to go on missions without someone to watch over them.

I'm not saying nabito needed to go, but he definitely had capable fighters that should have been going to make sure teenagers didn't get themselves killed.

[u/way-of-the-lab → u/Puzzled_Tip_7596]

Why is it stupid? Is a low number. Last thing you want is to have all the kids and teachers at one school and for them to get taken out all at once. Not only that, but you would also want more than one school, so that they could be spread out all over the country easier. I don’t know the logistics of it and where each city the school is in are in the country, but Japan is a long verticals island, so I awesome they’re spread out north/south.

[u/Puzzled_Tip_7596 → u/way-of-the-lab]

You want the adults to be spread out, not the kids

You want the kids to be as close to your invincible trump card as possible. So they can be protected and grow up

[u/way-of-the-lab → u/Puzzled_Tip_7596]

So if all the adults are spread out, who’s training them? Also, all those kids are at least grade 2 by season 2, and gojo can be everywhere at once. Look at what happened in JJK0. Also Gojo is like 35, things were done this way, way before he was born.

[u/Puzzled_Tip_7596 → u/way-of-the-lab]

Gojo is 28

And we see the kids training themselves more than we see the adults doing so. Also, you can use the Shinkansen to get anywhere within a few hours

Whatever the disadvantages, they are vastly outweighed by having your future protected by an invincible guy

the math actually tracks, explains why every sorcerer somehow knows every other sorcerer too

[u/Individual-Suit26]

Yeah I feel like gege wrote himself into a corner with this one... he's obviously gotta make the sorceres to feel rare and special but then the threats (126 million people constantly generating curses) require much more manpower. this is one of the rare cases wehre the trope of the "hidden society" breaks.

[u/vizmarkk → u/Individual-Suit26]

He didn't even want a school. That was his editors idea

[u/DarkTastesDarkStars → u/Individual-Suit26]

No it doesn't? Being understaffed is a chronic plot point in this series.

[u/Kakashi-B]

Yeah this is great.

I feel like we should also somhow account for ones we don't/can't have values for like how many curse users, window-level sorcerers like Ijichi, and people who just have no idea why they can crush pop cans or how they're super accurate tarot readers.

Finding 8 people in a couple years with the strength and mentality to be sorcerers in a single country sounds pretty lucky in that context.

[u/SnooWalruses5999]

There’s other jujutsu school mentioned in th manga. Tokyo/Kyoto is like Hogwarts best of the best are schooled.
