This is just capitalism applied to magical girls.
Anyway, one thing that seriously annoyed me is the ammo-control app on the tablet. Since ammo-reloading and the likes are controlled via software, why don't they just do it remotely? If - for some reason - it must be near the magical girl at all times, why not put it on a smart watch or use voice recognition or something for the magical girl to reload ammo more easily? Better yet, how about automatically reloading upon detecting a low ammo count?
It just doesn't make sense. The only explanation I can think of (that I will be satisfied with) is that the world of Magilumiere is affected by enshittification as well, and whatever I just suggested requires them to pay more.
