Megaton-kyuu Musashi

Ixia's residents believe they live in an ordinary town because their memories were rewritten to conceal humanity's near destruction by the invading Draktor. Teenagers are secretly selected from the shelter to pilot giant Rogue machines, including hot-blooded Yamato Ichidaiji just as memories of his murdered family begin to return. Alongside Ryugo, Teru, and other young pilots, Yamato learns to bring their separate units together as the Megaton-class Musashi while still pretending to live a normal school life. Contact with Draktor princess Arshem reveals fractures inside the enemy and proves that not every alien supports the invasion. As Ixia's manufactured peace begins to fail, Yamato must decide whether revenge is enough to define the future he is fighting for.
