Plot involves a guy who turned into a magical girl and must fight the noir for Earth. I only read chapter one, but I get the feeling it's a fairly cool, subdued doujin series.
Support the author if you read it. But I don't think many will read it even if it's free, because plebes can't fap to an action series like this and it's in moon to boot.
Update: *skims* wow what happened to this series? It's like it forgot what it wanted to be, introduced new characters, diminished the old ones, and turned into K-On SoL. What happened to the magic girls, the bromance, and the fights?
