Studio Colorido is getting good at making mid movies with somewhat good visuals here and there. The character designs were pretty generic but the white hair and oni horns were a nice touch to make them stand out.
Why this movie was mid? Well the pacing was out of the place, it would have worked better if it was a whole slice of life/fantasy series where they could have fleshed out the adventure aspects of it while also explaining the whole narrative better.
Well, here's hoping that their future works get good, this was better than A Whisker Away (same director) but not Penguin Highway (same screenwriter, but not the actual author).
