If there's one word to describe Reiji Ozora, it would be "quitter." He can never find the motivation to finish anything, and loses interest at the drop of a hat. This all changes when his best friend Maiko introduces him to the new game "Dragon Drive." In this virtual reality game, each player is assigned a dragon tailored to match their personality and strength. Reiji hopes for a big, strong, scary beast, but instead, he is stuck with Chibi, a cute, friendly-looking dragon smaller than he is. How disappointing—except it turns out that Chibi is the rarest dragon of them all!
