I got my replacement part from GSC today; instead of just sending me the red ribbon that was missing from Cirno, they sent me her whole torso part, so I was able to use parts from other nendos to make an Emono.
Black ribbon and legs from Kuroneko, head and stand from BRS. I don't have any spare stands or back hair plates, so I'm considering buying a cheap bootleg just for those parts, but I'm not sure, I'm not keen on supporting bootleggers, but I don't want to buy a random nendo just for two parts.
