When Aoko is talking about true magic with Soujuurou in Mahoyo, and she says this (emphasis mine):
what does she even mean here, in the emphasized part? Is it just that if you've managed to reach the root then you're part of the top dog club and you can do whatever, or is it something more specific going on here?「そもそも魔法は『根源の渦』にたどり着いた魔術師へのご褒美みたいなもので、たとえその術者に魔法を使う だけの肉体性能がなくても、根源へのができただけで魔術的にはやりたい放題ってわけ。パス路
要は、地球で一番のお金持ちになるってコト」
