Hatsune Miku
A series of rhythm games starting from "" were produced by Sega under license using Hatsune Miku and other Crypton Vocaloids, as well as "fan-made" Vocaloids like Akita Neru. TinierMe also made attire that looks like Miku's for their services, allowing users to make their avatar resemble her. The series has sold 6million copies. "" was developed for the Nintendo 3DS. 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.
Supercell (band)
Ryo chose to distribute his music on Nico Nico Douga because he liked the website along with its response system, which enables user's comments to appear overlaid on the video screen. Ryo did not originally intend to use Hatsune Miku as the vocalist for his songs, and most members of Supercell did not even know of Miku until after "Melt" gained popularity. Since Ryo did not know any singers, he was recommended by his friends to use Miku, which he thought was a good idea since videos using Miku were already widely being distributed on Nico Nico Douga at the time.
