Many people don't even realize Studio Ironcat has been publishing a shoujo title pretty much since day one, in the form of New Vampire Miyu. Conversely, they do not advertise it as such, focusing instead on the creative team behind it and its horror roots. Since completing Miyu, they have started its sister series Yui, and now will be publishing the more adult Dhalia. Speaking to them recently they indicated they fully intend to publish more Kakinouchi works in the future, which is a great sign, and will hopefully lead to more works of shoujo horror being published.
In its early days Ironcat was criticized for less-than-stellar touch-up work, reproduction and translations. However, they have taken great pains to rectify this, and the graphic novel collections of earlier works (like the early Miyu) feature corrected transfers and translations. Ironcat comics are notoriously hard to find, so check out their web page, www.ironcat.com, if you are having problems.
