Project Diva f is the console game's portable sibling, bringing pretty much the exact same experience to the PS Vita.
While beating songs, you'll score Diva points which can be used to purchase new costumes, furniture and other accessories for each vocaloid to personalize them to your liking. You can also hang out with Miku and play various mini-games and pet her head. I promise, it's not as creepy as it sounds.
