So a weird buy from my part, especially because this isn't a series I planned to pick up, it just happened the three volumes were available for cheap and the fourth and last one was finally published a few weeks ago.
Catacombes.
I am a sucker for zombie stories, though I have a preference for unusual settings, Gyo had fish zombies and mechanical legs, and Cradle of Monsters took place in an upside down boat (also the zombies were more akin to Resident Evil's Ganados).
Catacombes takes place in one of the most infamous places in France: The catacombs of Paris (and here's a spoiler for those who don't know what it is, though I think it's pretty popular already.)
For the non initiated, it's an old mine where the bones of centuries of Paris inhabitants have been dumped, it's notoriously dangerous because it is a labyrinth of massive proportion and is a famous destination for urban exploration, though this is highly illegal. Apparently underground societies do exist there and meet in the catacombs via openings that can be found in some places of the city, mostly through the Paris Metro system, those same openings are also used by Urban Explorers.
So Catacombes follows the story of a goth girl, Anahë, an artist and lover of Metal who explores the Paris undergrounds with friends. And I give it props for having zombies that don't look like a simple human with random scratches.
The manga is western, and strangely reads from right to left, like a japanese manga, a very unusual feature coming from a french based manga which usually reads the other way.
I don't know if scans of this exist, however I can recommend you all another french serie that was scanned: City Hall, a story where paper is the most dangerous invention in the world, as it causes anything written to appear or happen. Fans of Steampunk settings may pop a boner when reading it. I know I did.
EDIT: oh yeah forgot, if I did not want to pick it up before it's because the series was published very slowly. It took seven years to reach completion, for four volumes, it's pretty long.
