Hatsune Miku: Colorful Stage!

Hatsune Miku: Colorful Stage! (originally released in Japan as Project Sekai: Colorful Stage! feat. Hatsune Miku) is a rhythm game developed by Colorful Palette (a subsidiary of CyberAgent) in cooperation with, and published by, Sega. The game features the 6 Virtual Singers of Crypton Future Media – Hatsune Miku, Megurine Luka, Kagamine Rin and Len, Meiko, and Kaito – alongside the cast of twenty original human characters that are split into five themed units. Set in the real world where Virtual Singers only exist as fiction, the characters come across another dimension called "Sekai", which is created by the members' "true feelings".
