106m, the same guys that did the "Super Dreadnought Magical Girl" Doujin starring Alice as a giantess have been working on a new one, this time starring Sakuya.
It seems as if they're done with it and getting it ready to sell (though as with their last one, I'm more than a little confused as to how to go about purchasing it), although this time it looks as if they're also putting their own English version of it together that will be available down the road, so hopefully it's a bit more accessible than the last one appeared to be. 96m (the artist for the doujins) has some preview pages up on his blog.
This is both a heads-up to those that liked their last one, as well as something of a "request" for anyone that can navigate and info-hunt better than I can to see if, when, and how the comic is available for purchase. I don't think they did digital distributions of the last doujin, and the site that sold the physical copies wouldn't ship internationally (unless I was mistaken), but hopefully with them actually putting together an English copy, that won't be the case this time.
