Hatsune Miku And The Vocaloids Meet Regular Humans In Sega And Craft Egg’s Project Sekai


project sekai 1

Today, Sega held a livestream for Project Sekai, a new mobile game featuring Hatsune Miku and the Vocaloids developed by Colorful Palette, a new studio established by BanG Dream! developer Craft Egg.


Check out an overview trailer below:


Project Sekai takes place in both modern Japan around Shibuya, and is essentially like our world, where Miku, Len, Rin, Luka, Kaito and Meiko are virtual singers that are used to sing the songs of creators. However, one of the protagonists, Ichika Hoshino, one day accidentally stumbles upon ‘Sekai’, a mysterious world born from “thoughts”, and is thus also the place where songs are born.

As Sekai is created from thought, it can take on many forms, and Miku and the others take on many different looks with different outfits as well. Worlds are born in the realm of Sekai from people’s thoughts, and by finding the true name (meaning) of the song, and meeting the Vocaloid of that world, and singing the song together, the song is finally born into the real world with its name.

The game has been in development for the past two years, and began when the developers met during the Hatsune Miku collaboration with the Shinkalion anime.
