I usually buy each new issue of the DollyDolly magazine. It’s a japanese magazine about dolls. Each time you can find two pages centered on Odeco & Nikki: one page of strips telling a story, and a one page picture of the real dolls, related to the story. They’re wearing an outfit designed especially for the magazine, for which they give the pattern.
I was really surprised to see two dolls that I didn’t know in the last issue (n°18)!
Are they custom dolls? No! The legend says that they are the future January release: Obake no Odeco & Nikki (which mean Ghosts Odeco & Nikki). I don’t think those will be their stock outfits, but at least we get to see what the doll themselves will look like! I think they’re rather cute, don’t you?
