*Mumbles* My first post was eaten.News from JapanSquare Enix
plans a 3rd 'comic CD collection' to be released on May 31st. Title has not been revealed. Basically drama CDs, but unlike the free drama CDs that come with some monthly GANGAN
editions, comic CD collections are sold separately. Scenarios are original, written by Arakawa Hiromu (manga artist).
The first 2 comic CD collections can be seen here
#1 - 鋼の錬金術師 砂礫の大地 (Fullmetal Alchemist - Land of Deserts)
Based on the original novel / story that was never included in the manga, but later included into the anime TV series, it focuses on the Elric & Tringham brothers. Since this drama CD was made before the anime, the voice cast was completely different (with the exception of the Tringham brothers).
#2 - 鋼の錬金術師 偽りの光、真実の影 (Fullmetal Alchemist - Light of Lies, Shadow of Truth)
Original story featured no where else.Sources
