These adorable hime-gyaru Unoas are owned by a Japanese small company/doll collector named Aki. She seems to be a jack-of-all-trades where dolls are concerned! I love her use of the best, most elegant to-scale props and the candy-pastel, purikura-like feel of her photography! Not to mention she does all of her mod and faceup work herself -- you can see a pic of her tools in the 'custom' gallery. She even makes the puffy hime-gyaru wigs she puts on her magnificent girls! Last but not least, their beautiful clothing is made by her and apparently she runs auctions for some of the pieces.
