Helping with Magical Girl Noir Quest on /tg/ is mostly up. You're being mentioned in its irc channel quite a bit, by the way. We already have Dan Kim, and thus look for you and Velox, to complete the holy trinity of 4chan drawfags.

An alcoholic and chain smoking magical girl who may or may not be Homura, running a magical girl para-military organization, trying to become a better person step by step. Maybe save the world, if she doesn't screw it all up, which she probably will.
Really grew over the years. The expanded setting is being done on by an outer circle of writefags, gets an outrageous amount of fan art. Contains a lot of crossovers, in part to make a homage to the whole magical girl genre, in part because it's more fun that way.
