GungHo Online Entertainment has announced a second Grandia collaboration project for the free to download, but Japan-only PlayStation Vita game Picotto Knights.
As with the last event, "Cocoroid" characters based on Grandia characters will be distributed online, and all you have to do to retrieve them is to log in to the game. This time around, the distributed characters will be Mullen, Leen, Nana, Saki and Mio (check the link for images). One character will be distributed per day, starting on April 19th at 4am JST, with the event ending at 4am JST on the 24th.
If you own a PlayStation Vita, you will need a memory card that is linked to a Japanese PSN account to be able to download Picotto Knights. The region of the system itself doesn't matter.
