As you can probably tell by Satanophany's average rating on here, it isn't a manga for everyone. But it's a manga for me, dammit, and I made the mistake of becoming obsessed with it. I really hope someone continues the translation in the future. Everything about the manga is silly and over the top. It features female protagonists killing freely, and lots of fanservice and sex. There aren't a ton of action manga out there with women as the main combatants, so I loved to see this one. It really gives you everything you'd want. The art is great, the artist is well-suited both to fanserviceand fight scenes. There is a lot of gore and the girls are beautiful and form a good ensemble cast of unique and memorable personalities.

When the manga begins, it has kind of a Battle Royale premise, but as it goes on its cast begins to function as more of some kind of ridiculous special ops team. Once they start working together (and venture beyond the walls of the prison) the manga really gets good and its possibilities open up. This is why I'm dying to read more, the last translated arc, as of this writing, just expanded the scope of this manga so much.

Everything about the manga is silly and that's why it's good. It is trashy and exploitative, but it's fun. Like a great B movie it entertains with its rawness and its willingness to hold nothing back. If you like female protagonists/female killers and can appreciate a pulpy and tasteless horror movie I strongly recommend this manga.
