Strain: Strategic Armored Infantry is a mecha anime series by Happinet and Studio Fantasia. It premiered across Japan on WOWOW from November 1, 2006. A manga adaptation is being serialized in the Dragon Age magazine. The concept of the series is loosely based upon Frances Hodgson Burnett's novels, most notably A Little Princess (1905), but also Little Lord Fauntleroy (1886) and The Secret Garden (1911). The series also draws some elements from the Gundam franchise. In 2008, Texas-based licensor FUNimation Entertainment acquired the license of Strain: Strategic Armored Infantry. The anime was available in a complete DVD release on January 27, 2009, across North America.
