Xam'd: Lost Memories

Sentan Island sits in the Yuden Sea, living in a hazy calm far removed from the conflict between the Northern Government and the Southern Continent Free Zone. Akiyuki Takehara grows up there with his mother, Fusa, while remaining separated from his father, Ryuzo, the town doctor—yet their connection endures.

After delivering the lunch Fusa prepares for Ryuzo, Akiyuki heads to school and is suddenly swept into an explosion alongside his friends Haru and Furuichi. A strange light pierces his arm, bringing searing pain, and before he can make sense of what’s happening, a white-haired girl from his bus ride leads him toward a power he never imagined.
