See our entry 40400080 for content description, and we are as always indebted to Wikipedia for giving us information about this character:  “Hatsune Miku (Japanese: 初音ミク), officially code-named CV01, is a Vocaloid software voicebank developed by Crypton Future Media and its official anthropomorphic mascot character, a 16-year-old girl with long, turquoise twintails. Miku’s personification has been marketed as a virtual idol, and has performed at live virtual concerts onstage as an animated projection (rear-cast projection on a specially coated glass screen)”.  The search for this name became complicated, so you might want to double-check if you don’t already know.  Unopened, unused.  Grade: 1
