The first costume with Roxas' new wig |D The idea came from us and we wore these costumes with the whole group including Riku, Xaldin and Kairi. It was a lot of fun to design Axel's 'Ingame' outfit for drives.
The "Lost Drive" was created from the idea to give every character a driveform. But the already existing forms didn't seem very appropiate for most of the characters we had in our group. Plus we wanted to make it violet! So we thought it would be cool to give nobodys a driveform - thus the Lost Drive was born. :D
