Fun fact. This game was recorded in L.A. and Taliesin Jaffe had Christopher Bevins help with the script adaption for the game and around the same time Funimation announced the license for the anime series. Being the "Basara expert" Chris Bevins managed to get the job of directing and writing for the anime's English dub. With the contact info he had available, asked some of the game's cast if they would reprise their roles for the anime.
