Planet Machina is the home of all Card Bots, a highly advanced mechanical civilization populated by intelligent machines. The supreme ruler and creator of all Card Bots was the supercomputer Deus Machina. The planet was home to an elite guard—the Cosmo Guardians—who maintained order and fought the wild Card Bots. All Card Bots are created from a unique purple metal called Machinasium. At the end of its life cycle, the planet's core became unstable, leading to a catastrophic explosion and the destruction of the entire world. Deus Machina foresaw this catastrophe and created the Metal Bracelet device to help the Card Bots survive. He tasked Blue Cop with finding his friend on Earth. After the explosion, the surviving Card Bots scattered across the galaxy in escape pods and eventually ended up on Earth.

An ordinary boy from Motown, emotional and curious, who loves BMX. He accidentally discovered the Metal Bracelet when his belongings fell off a bridge, and the device automatically attached itself to his wrist, making it impossible to remove. It turned out to be a treasure from the planet Machina, capable of sealing and summoning Card Bots, and the bracelet itself chose Jun as the "chosen" leader of all Card Bots. Blue Cop explained to him that from now on, Jun would help the Card Bots adapt to Earth and protect them from humans. Jun initially doubted he was ready for such responsibility, but he agreed, because he never considered the Card Bots subordinates, only friends.
