The MC's relationship with money continues to baffle me, but since it's been brought up again I gotta ask - what the hell is up with this girl's parents?
They took absolutely everything from her place, went to the landlord to have her kicked out, and went to the school to have her withdrawn - assumedly all within a single day. I have to assume the reveal will be that they're very powerful (either literally or metaphorically) because how did they manage to do all that so quickly and with nobody asking any questions?
Obviously there's also a question of "why would they do that?" for the parents, but I'd apply that to the landlord and the school as well - why would the landlord just kick a tenant out even when the rent for the month or whatever was likely already paid? Why would a school just drop the kid without any further procedure, especially when the kid shows up the next morning going "I have no idea why they did that, I definitely should still be here"? Did the parents threaten the landlord and school into doing what they want, or are they also inexplicably evil/stupid?
Between the adventurer's guild and the school it seems like all the institutions in this world will just roll over and do anything anyone tells them to do without any sort of checks or other procedures.
