Metal Cardbot

After the machine world Machina is destroyed, the sentient Metal Cardbots are scattered across Earth and conceal themselves as ordinary vehicles. Jun, an energetic elementary-school boy who loves BMX riding, unexpectedly finds the Metal Breath, a device capable of linking him to these powerful machines.

His first encounter with Blue Cop pulls him into a hidden conflict involving Cardbots with very different motives. By using special cards through the Metal Breath, Jun can awaken their abilities and bring them under control, but every new machine he meets makes it clearer that the mystery of Machina's destruction has followed its survivors to Earth.
