Music Girl Hatsune Miku is a new iOS app created as a joint project between Crypton Future Media, SEGA, MARZA ANIMATION PLANET (which created many of the 3D CG for SEGA’s games, including Project DIVA) and iOS development firm W Rock Games. A teaser video on YouTube tells the user to enjoy listening to music together with various versions of Miku as it shows Miku in various outfits with a LamazeP song playing in the background. This ad was apparently shown at the live concerts on March 8-9 according to the video description.
W Rock Games also released a previous app in the Music Girl series called Music Girl Nene. In this app, a 3D avatar named Nene listens to songs together with you. Any song from iOS’s library can be played back and the app will synchronize Nene’s movements if tempo information is present in the song’s tags. The site hints at good things happening if you listen to a lot of songs with Nene. Furthermore, various “communication” opportunities show up, with the user being able to choose from several possible replies to questions Nene asks. Making her happy will accrue points and hitting 100 points will cause her to give you an item as a present. Furthermore, there are several costumes to choose from, with more costumes and accessories available as in-app purchases. There are also several voice packs for her as well, making her speak and behave differently, such as the tsundere pack. It is believed that Music Girl Hatsune Miku will be a similar app.
