Yet another insipid, utterly puerile work from Go Nagai. Story elements are borderline nonsensical, quickly mashed together tropes recycled from his other works; the only interesting thing about it is that this garbage ran in Margaret, making it ostensibly shoujo (Nagai did other shoujo works though- a number of other early magical girl titles, most of which seem to have been more successful than this).
The art is his usual- though rather than over-the-top violence, this work spends an excessive amount of time highlighting the villains' sex dungeons where they have wild bisexual BDSM threesomes. If that sounds interesting to you, please remember what Nagai's art style looks like. A solid third of the last book is just the "pretty" boy love interest in duress.
Avoid this series unless you're a Nagai completionist; vintage shoujo manga fans, Margaret enthusiasts, you will find nothing of interest or note here.
