In Thrace, Arion is taken from his mother Demeter by the god Hades. In the Underworld, Arion is trained to be a warrior. His training is driven by revenge: Arion was told that his mother's blindness was caused by Zeus and Zeus' death will remove the curse. Finally, Arion and Geedo (a huge ape-like creature who had become Arion's friend and companion) left the Underworld to find Zeus. Seneca, a small thief, makes off with Arion's sword and this leads Arion to his first encounter with the forces of Zeus, commanded by his daughter Athena. Arion is captured but is later set free by Lesfeena, Athena's mute serving girl. As Arion rejoins Geedo and Seneca (and worries about Lesfeena), the forces of Zeus and Poseidon face each other in battle. In the background sits the scheming Hades, and the calm Apollon who seems to have plans of his own.

Two years ago, a mysterious wind swept over the Earth without warning, taking everyone's memories with it. Not knowing their names or even how to speak, cars crashed, planes dropped from the sky, and society crumbled in an instant. One young man happens to wander into a military testing facility, where he meets Johnny, a young boy who underwent experimental memory enhancement treatment and could, therefore, still remember who he was. Johnny names the young man Wataru and teaches him everything that he can before his frail body fails him. Wataru sets out on a journey to see if he can find other people like him, and in San Francisco, he meets a mysterious silver-haired woman named Sophia, who refuses to speak about her past. Sophia says that she is heading to New York, and decides to travel together with Wataru. As the pair make their way across America, they learn about what has happened to the rest of society, and what the essence of humanity really is.
