Hey guys? I discovered that someone actually made Sariel before. The person uploaded on this site:
http://muvluv-alternative.game-server.cc/cgi-bin/nico-up/upload.cgi?mode=dl&file=5702
However, since the site is now down, I don't think anyone knows where to find her now. Just letting you guys know.
