Is this an innovated, inventive, original series that does something new and different? Not in the slightest.
Would I complain about getting more from this inoffensive, nice-enough series that at least so far doesn't seem to be tripping hard into most of the annoying Japanese trope boners that manga love (She's a teen, but isn't a loli. There's no jerking it to slavery. The MC is overpowered, but at least there's no "everyone treats me like a loser but I'm actually the strongest" or "MC succeeds basically by accident and has every girl in the world throwing themselves at him because he's generically nice")? Absolutely not.
so if Cnnuy wants to keep going with it I'd hardly complain. I need some low-effort, non-grating standardness to keep me invested during lulls between the series I really like getting released. Plus that one about the teacher training the Demon King's daughters just ended kinda shittily after being fairly entertaining most of the time and I think this can fill that void.
