Just read the light novel. My thoughts:
The writing is good but clearly a begginers work. Plot is all over the place and not in an expert multiple view sense but an uncontrolled one. But the author has a clear strong vision in writing that keeps the interest.
There is good counter forces to the main character which suffers a bit of Isekai'itus, with complete do anything with the power of imagination magic skills. The life and political circumstances help keep her in check and allow other characters to have engaging personalities. That said no one else is fully developed, just lots of partially developed characters.
The mystery of things is likely the most engaging of the stories conceits. But it does feel like it keeps forgetting bits of its own mystery plots. And it risks devolving into kids super power battles with the dark super powered kid vs the light one.
Overall enjoyable but also messy. It feels a sight better then many simple stories we get each licensing season. I hope it evolves and not devolves.
Now to read everyones comments.
