A mysterious orb envelops the city of Tokyo. All forms of communication are severed, leaving the inhabitants of the newly dubbed 'Tokyo Jupiter' ignorant to their fate. Along with the United Nations, a special organization known as TERRA is formed: their mission is to liberate Tokyo from the otherwordly MU--those responsible for Tokyo's capture. Tokyo citizen Ayato Kamina's life is about to undergo a drastic change. MU agents attempt to kidnap both him and his childhood friend Reika, and a sassy TERRA operative brings him face-to-face with the mythical giant robot RahXephon--a force he alone has the ability to control. With everything he has ever believed in falling to pieces around him, Ayato resolves to fight the MU and protect Reika at any cost
