Hobby Stock JP has uploaded some review photos of the exclusive HoiHoi-san [Alice Ver.] kit which was sold at the Dengeki Character Festival.
It seems to me like there is much more assembly required than I had anticipated for this plastic kit.
And if you good with DIY, then you might want to spray paint HoiHoi-san with your favorite colors ^^
