that was really interesting! pacing could have used some work, but i liked the plot and setting a lot. ending honestly just felt like how nanoha always ended its seasons: central conflict tied up, antagonists befriended or neutralized/allied... it's a very neat way of wrapping things up, but in exchange it doesn't leave much impact. i think all in all it works though, at least for me. solid 7/10
i haven't checked also, but im guessing this was a web manga? the art is rough in places, so im guessing this was an indie project and story the artist just really wanted to share. kinda inspiring tbh, i need to follow their example
