Deep down Trinity is the major soulful school, because it's the only school that's a school.

If you tell an Abydos story then it's just a story about politics and land development, a Millenium story is just about the devs metaposting about video games or the engineers randomly building rapebot 5000 and for some reason it went wild, gehenna story is just about uptight Hitler cops trying to take control of the population and enforce order on chaos as hot springers blow up city hall and they have to call in BatHina to save the day, Hyakki story is about festivals, shanhaijing story is about tradition.

Trinity story is the only setting that feels like it's about students that go to school, take tests, get grades. Friend groups and cliches, normal shit kinda.
Wildhunt has a similar feeling so far
