Xam'd: Lost Memories - S01

Sentan Island is a small island surrounded by the Yuden Sea. It sits in a dreamlike quiet, cut off from the war between the Northern Government and the Southern Continent Free Zone. Our hero, Akiyuki Takehara, lives on Sentan Island with his mother Fusa. He is separated from his father, the town doctor Ryuzo, but the bond between father and son remains. One day, after bringing Ryuzo the lunch Fusa made for him as usual, Akiyuki arrives at school, where he is caught up in an explosion along with his friends Haru and Furuichi. The explosion gives off a mysterious light, which enters Akiyuki's arm and causes him terrible pain. He has no time to understand it, though, as the white-haired girl who rode the bus with him leads him to a power unlike anything he has ever known.
