Hatsune Miku and Future Stars: Project Mirai

Hatsune Miku and Future Stars: Project Mirai is a 2012 rhythm game created by Sega and Crypton Future Media for the Nintendo 3DS. The game is a spin-off of the Hatsune Miku: Project DIVA series of Vocaloid rhythm games and was first released on March 8, 2012 in Japan with no international release. Like the original the game primarily makes use of Vocaloids, a series of singing synthesizer software, and the songs created using these vocaloids most notably the virtual-diva Vocaloid Hatsune Miku. It is also the first Project Diva/Mirai game to include a Vocaloid made by Internet Co., Ltd. and the mascot Gumi appeared as a guest star.
