Kat is the center of PlayStation Vita attention in Japan with a budget re-release of Gravity Rush in Japan and a Picotto Knights crossover. Picotto Knights is a free to play, four player, belt action RPG from Game Arts which is kind of like Dragon’s Crown with cutesy Cocoroids as characters. A new collaboration adds characters like Kat and Unica to the game.
By logging on to Picotto Knights between April 25 and May 9 you will get Yunica as a login bonus. Clear a special mission with Yunica and you’ll earn a special title. Login again with that title and you’ll get a Gade Cocoroid. Beat a mission with Gade and you’ll get another title plus a new Cocoroid when you login next time. Kat is a rare Cocoroid and she has a mission that unlocks a special title too. It’s unclear how you get Alias and Raven, but they are in the game too.
Picotto Knights also has a bunch of characters from Grandia in the game and dozens of original Cocoroids. GungHo Online Entertainment America said Picotto Knights would come overseas, but we haven’t heard anything about it since. You can grab the game for free if you have a PlayStation Network account registered in Japan.
