Project Sekai: Colorful Stage!, often shortened to Project Sekai, is a rhythm mobile game from Sega and Crypton Future Media pairing Hatsune Miku and the other Vocaloids with several original idol-group casts across musical, story-driven worlds. Its blend of rhythm gameplay and Vocaloid crossover appeal built a large, active fanbase since its 2020 launch. Project Sekai hentai doujinshi draw on both its original casts and the Vocaloids themselves.
