Xam’d: Lost Memories, known in Japan as Xam’d of the Forgotten Memories, is an anime series, conceptualized by Bones and co-developed by Sony Computer Entertainment, Aniplex and Bones, which made its debut on Sony’s inaugural launch of the PlayStation Network (PSN) video download service at E3 in the United States on July 16, 2008, in Japan on September 24, 2008.
Sentan Island exists in a state of dreamlike tranquility, surrounded by the Yuden Sea, cut off from the war between the Northern Government and the Southern Continent Free Zone. Akiyuki Takehara lives on Sentan Island along with his mother Fusa. Despite his mother’s strained relationship with his father, Ryuzo, the town doctor, the bond between father and son remains strong.
One day the island’s tranquility is shattered, when Akiyuki, along with his best friends Haru and Furuichi, are caught up in an explosion on a school bus by a mysterious pale, white haired girl named Nazuna. The explosion produces a mysterious light which enters Akiyuki’s arm and a blue gem appears. With no time to understand what has happened, and a brief exchange between Nazuna and Akiyuki is transformed into a creature called Xam’d. As Xam’d, Akiyuki uses his newfound powers to fight off monstrous invading forces to save Haru, only to be stopped by a mysterious girl who offers him a choice: come with her and live, or stay and turn to stone. Accepting her offer, Akiyuki embarks on a journey of discovery that will take him to new lands, and help him understand the connection between himself and the world of Xam’d.
The series received its television premiere across Japan on MBS, CBC, Tokyo MX and other Japanese broadcast networks from April 2009, featuring new opening and ending theme sequences.
