It looks like a doujin group that specializes in creating 3D games. The biggest one in development right now looks like "Magical Battle Arena", featuring characters from Nanoha, Lina Inverse, Cardcaptor Sakura, and some more that I can't identify. A demo is up for download here so check it out, it's really cool.
