The story was completely lacking; there was no goal, stakes, or actual wordbuilding until the final episode. The characters were all pretty one-dimensional, the strongest of which was definitely Mile, although the "small boob joke" (you know the one), and her constantly breaking down crying at every opportunity didn't exactly help. The boob joke has to be the most unfunny joke in anime, it's been reused 1000 times over, and it's just incredibly uncomfortable to have a 12 year old comparing her bust to a 9 year old, and this being a recurring theme in just about every episode.
With the weak characters comes weak, uninspired dialogue that seems to have been copied right out of the "stereotypical anime lines" booklet. Ninety percent of the episode plots are predictable, and uninteresting; for example the classic "tragic backstory" is revealed where bandits killed a character's parents and such, and she hates them so much she wants to kill them. Other characters convince her killing is wrong, they cry for a little bit and the episode is over. I'm just so incredibly uninvested I can't take it seriously, and it's painful to watch.
There were things minor things I definitely appreciated about the show, but they're about equivalent in scale to nitpicks, so I don't think they're really worth listing out. If I let myself write any more this will look more like a rant than a review, so I'll leave it here. I don't recommend this at all unless you're into lolis and have never seen an anime/isekai before. 4/10
