Long, long, ago in a universe far. far, away, there was a planet called Halpha. On that planet lived Halphanians who are part of an organization known as ARKs. There they lead a battle against an unknown enemy known as DOLLs. The fight against the DOLLS has been waging for hundreds of years. No one knows where they came from or why they are attacking the people of Halpha. The members of ARKs are made up of skilled individuals from Halpha, but there are also those with a different background....

They are known as the Meteorn, this is the name given to them by the Halphanians to the mysterious people who arrive frequently by the way of the pod, from the sky, on Halpha. The Meteorn have no memory of their life before they arrived. Similar to DOLLs, no one knows where they come from, and the reason for their arrival on Halpha. However, their skills as ARKs are unparalleled. Many of them decided to live together with the people of Halpha and fight together as a united front as ARKs against the DOLLS.

And now as a new member of ARKs, one Meteorn is arriving at the biggest city on the planet known as CENTRAL CITY.
