ドラゴンドライブ, 드래곤 드라이브, Doragon Doraibu, Rồng ma trận
Reiji Ozora thinks he's no good at anything--especially schoolwork! Then one day he's introducted to a game called Dragon Drive and gets his very own virtual dragon named Chibi. Small and weak, Chibi appears to be as big a loser as Reiji! But after their first battle, Reiji realizes there may be more to his tiny friend than meets the eyes.
