Synopsis
A project commemorating the 150th anniversary of Yokohama City. On Planet Abel, humans and robots live together. One day, a mysterious stowaway aboard a transport vessel attempts to invade the planet, but is discovered by Apollo (Hayato Ichihara), a robot who looks human, and Mikaru (Aya Ueto), a human who looks like a robot. The stowaway possesses a memory chip containing the latest camouflage software—the enigmatic "Cipher" OS. Apollo takes the Cipher chip purely for fun, unaware of what he is getting into. He suddenly begins acting strangely, but Mikaru has no idea what is wrong or that Cipher is the cause. What exactly is Cipher? What secrets does it hold? Apollo and Mikaru must unravel a mystery that spans the past, present, and future to find out.
