Reiji Ozora is a chronic quitter who never completes what's assigned or handed to him, but one day Maiko, his closest friend, walks him to a local arcade where the latest game craze is happening: Dragon Drive. After meeting Chibi, a seemingly meek dragon, Reiji wants to make himself and Chibi stronger. To obtain this strength, both are taken to a secret training room in the "D-Zone", the same room Maiko and Daisuke snuck in earlier upon seeing a strange dragon appearing in the sky. The dragon suddenly absorbs them into another Earth known as Rikyu, where they meet Meguru, a girl who was also transported to Rikyu. There, the elder of the village reveals the intentions RI-ON, the group behind Dragon Drive, have trying to obtain the Jinryuuseki stone, which grants its welder the power to control all dragons in Rikyu.
