From Kodanclub:
"FAIR PLAYS" is an action RPG that has become a global sensation. In this story, it is finally brought to Japan. The game is played inside a computer realm and is designed so that players can fight each other--wherever in the world they might be--simply by manipulating dolls called "frames."

FAIR PLAYS is only supposed to be a game, but when young Kyota finds a "fairy" frame called Bobo in the garbage and tries him out, he and his friends are pulled inside the world of the game. They soon find themselves in a place called Ashliana, a country dominated by Gomao, the enemy boss who is an evil, havoc-wreaking demon whose only purpose is to kill. In order to save Ashliana, Kyota and Bobo must somehow become one.
