Pantsu-heavy PSP music game Hatsune Miku -Project Diva- features a 3D version of Vocaloid character Hatsune Miku.
To get that 3D character modeling, SEGA enlisted child star Yui Ogura to do the motion capture. The kicker? According to Hatsune Miku's official profile, the character is 16 years old. Yui Ogura is only 13. What gives?! It's motion capture!
