Hoshizaki definitely has some judgement issues with her manipulative plans and how she charges head first into an opponent that easily beat her, twice.
I wonder if there is any relation between the Yandere and the magical girl? That there are seven and apparently known about in the psychic world is amusing to me in a "author-kun doesn't want to spend too much time introducing this" kind of way. I like the interplay here and they might as well add in mutants, demons, or something else; Why not?
The only thing that is really stretching the believability of the story is the pretext that these supernatural entities are being covered up when entire planes and craters happen on the reg.
Speaking of arial confrontations, surprising that we never hear or see the other magic user that fought Pii-chan above the battlefield in ep 4. Also, for some reason, I like the way this was handled better than in... Slime season 2 even though the scenarios were very similar. I don't feel like Sasaki's character was compromised even though he essentially drew the same conclusion that Rimuru did in slime isekai. Here, Pii did the deed and mentioned that there was no need for them (the soldiers in the army) to suffer even though they were all going to die. The same cavalier attitude towards death, but just that hint of remorsefulness and no thin rationalization kept me from turning on Sasaki as a genocidal maniac with a God Complex. Him gushing over his cute little bird also humanizes him.
Obviously vastly different shows, but the similarities I thought might be worth mentioning since I was bellyaching about that at the time.
Also, looks like the ED wasn't prophetic; no signs of teaching the little miss magic.
