Falsely banished as a criminal, Kulon landed on Earth among the other Rukeitai. Being a speedster, stated to being the fastest in the universe, he caused some ruckus while being chased by the police. He was arrested in the first place because he enjoyed giving other beings the same feeling he had with his speed, but unknowingly gave a ride to criminals. Ultimately, he was taken in by Sadamitsu, where he served a role similar to that of a sidekick&#039;s, usually being used as a motorcycle. He proves to be very loyal, as he obeys Sadamitsu&#039;s requests even when he is obviously frightened.

Sadamitsu, a high-school delinguents turned to a masked-hero, while not dealing with his rocky relationship with the strong female protagonist, he puts on a motorcycle-helmet-like mask and becomes a semi-robotic superhero who fights. He is assisted by other possibly- mechanical creatures in order to save the earth from the invasion of 20,000,000 escaped alien convicts.<br><br>
