To be fair, with how the puppetry magic is shown here, it's a lot more complicated that your basic examples
you basically have a telekinetic powers, and from what we know there is currently no way for people to know if something is being controlled by the magic or not, if you can't even...
This development doesn't really seem to be good if he loses, since if for some reason the way he would say his crush is by screaming, there's a chance that the glasses girl would hear him and proceed to chase him too
What do you mean by demographics?
Also man wtf, if anything doesn't that just scream how effective and scared they are with technology
now i wonder, what happens if the US transfer nihonkoku shoukan style to this world lmao
