Reception.
The OVA series has been described as "a visual delight" which "harkens back to a simpler age, when the important thing was that the characters looked cute and the action looked cool", even though the "plot fits together, but only barely". While based on shōjo manga, the series contains intense and graphic violence, which is not typical for most shōjo works. The anime is considered "a little bit better than average, though it "doesn't feel finished", but it is "better than the vast majority of 'magical warrior series.
