Here's the story behind this: before the season started, I looked up this series because I was curious. I found out that it had a prequel manga, but I couldn't find any raws, or even any photos of it. Then, yesterday, I decided to implement the downloader for the other NicoNico manga viewer. I noticed that the first issue of SDMP, the magazine for this, was released on Nico on the same day, so I decided to pick it up because I like the anime so far (and it's only one volume).
Anyway, the LN illustrator is drawing this manga. The editing department and the LN illustrator should get some sort award for that, because it's frustrating to see manga publishers use their adaptation deals to test new artists (see: Fractale).
