The two-episode OVA Senjou no Valkyria 3: Dare ga Tame no Juusou is created by studio A-1 Pictures, and follows the release of Sega's PSP game sequel Valkyria Chronicles 3: Unrecorded Chronicles. The game is once again set in a war-torn Gallia from an alternate history Europe in 1935, but this time tells a different story, about the Gallian Army squad 422, also known as the Nameless (since all its members are referred to by number, rather than by name).
