The official website of the BONES anime studio's Bōnen no Xamdou project is streaming a trailer. (The promotional video requires Microsoft Windows, Internet Explorer 5.5 or higher, and either Adobe Flash Player or Windows Media Player.) Xamdou is the latest in-house creation from animators of Fullmetal Alchemist and Eureka 7.
The story follows a boy named Akiyuki who is heading to school with two friends when an explosion occurs. In the mysterious light from the explosion, Akiyuki transforms into a creature called Xamdou. Xamdou goes on a rampage which is only stopped when a red-haired foreign girl appears.
