After a month of teaser videos, Sega finally revealed the identity of their mysterious Project 575 on July 18. The project consists of an iOS app and PS Vita game.





The iOS app, titled Song Composer 575, will include a voice synthesizing software similar to Vocaloid. There will be two available voices based on the previously revealed characters, Azuki Masaoka and Matcha Kobayashi. Once you create a song, you can share it or collaborate with other users. To promote the app, Sega has already distributed it to popular Vocaloid composers.

The app also lets you interact with the girls, watching them dance and dressing them up in different clothes, and taking augmented reality photos of them. Song Composer 575 will be released on July 26. As a bonus, people who preregister for the game will receive a waitress costume for Azuki and Matcha.





The PS Vita game, titled Song Builder 575, is a rhythm/puzzle game in which you read lyrics to a song as it plays, and you must pick syllables to fill in blanks. Thanks to the Vocaloid engine, the girls will sing whatever syllable you choose, letting you customize the lyrics.

Song Builder 575 will be released in 2014 and come loaded with the highest rated user-generated songs made with the iOS app. The game will also be available to play at this year’s Tokyo Game Show.

Along with the iOS app and Vita game, Sega is working with other companies to create a manga, T-shirts, iPhone cases, and other goods.

Azuki is an energetic girl who sometimes acts without thinking, and Matcha is a calm girl who likes to act arrogant and draw fan comics. They are both designed by Hiro Kanzaki, who also designed the characters of the novel/anime series My Little Sister Can’t Be This Cute. Azuki is voiced by Yuka Otsubo, whereas Matcha is voiced by Ayaka Ohashi.
