#also me: is the cram school inside or outside of the seireitei? is it for profit?

[recurring-polynya]

watching bleach #046: Authentic Records! School of Shinigami again (for reasons) and among the many weirdnesses of this episode is the fact that it seems to be, like, the first day of school, or at least the first week, but everyone already knows how to cast a shakkahou and enough about swordfighting that they are already sparring. And if admission were for nobles only, it makes sense that this is stuff you might have learned in private tutoring or whatever, but how the heck is someone from Bumblefuck, Rukongai supposed to know this stuff? I mean, maybe you just have to sit in the back and be embarrassed if you don't know how to do it, idk. My real question is: is there shinigami cram school, and did Momo go? (of course she did)
