Miku's appearance in this game is based on the Nendoroid series of figures. Hatsune Miku is also briefly referenced in the game "Recettear", where a young man stargazing sees "The Green-Onion Girl" constellation. Also, in 2013, Saki Fujita voices Fei-Yen HD, a character based on one of Hatsune Miku's modules, in "Super Robot Wars UX"; this appearance does not use Miku's vocal library.
Zoome
zoome's popularity boomed via Hatsune Miku at the end of 2007. Nico Nico Douga, the fostering site of the voice synthesis software, became involved in a scandal which caused some of its members to move to zoome. Dwango, the owner of Nico Nico Douga, had registered the copyright of a Hatsune Miku song to the copyright management group JASRAC under the name "Dwango", without permission from the song's author, sparking outrage among Vocaloid fans. Sometime before the scandal broke out, ACCA had opened a Vocaloid video hosting circle , which was officially recognized by Hatsune Miku's developer, Crypton Future Media. The scandal on Nico Nico Douga and the official recognition in zoome lured many members away from Nico Nico Douga to zoome. As a result, Hatsune Miku videos became one of the mainstays of zoome, and zoome became a leading competitor able to challenge Nico Nico Douga's monopoly of the video hosting service industry in Japan.
