Looks like the Vocaloid mascot, Hatsune Miku is going to get her own game on the PSP now instead of just being a sub-character like on the DS' "13 Year Old - Hello Work".
While tapping away at the four buttons (× ○ △ □) in time to her songs, players will be able to see a close-up shot of Miku making various expressions by fulfilling the right conditions. And if your timing is really good, you'll even unlock a challenge where Miku dances away.
Besides tapping buttons in time to her songs, players will be able to enjoy various short stories and go collecting parts to allow them to decorate Miku's room. Miku's behaviour will change depending on what her room looks like.
Game is over 40% complete and will be coming sometime next year from Sega.
