Byston Well is a world where people go when they die. It is normally unreachable from Earth for it exists between sea and land. Only those who can open the Aura Road can pass through. Dwellers of Sea called the A-Fellario are able to open the Aura Road, and one of them named Silky Mau is forced to do it to snatch a young motocross racer named Sho Zama. Sho finds himself in Byston Well and his role is to pilot an Aura Battler. The Aura Battler is a giant robot warrior of immense power that can only be piloted by one with a strong Aura. All people brought from Earth have that Aura, but Sho's is exceptionally strong. His new master is Drake Luft, but Sho soon finds that Drake's motives are more complex than he realizes...
