Dragon Drive

Dragon Drive is a Japanese manga by Kenichi Sakura published by Shueisha and serialized in the manga magazine Monthly Shōnen Jump. Publication ended in 2006, with a total of 14 volumes. Dragon Drive follows lazy junior high school student Reiji Ozora who routinely gives up on everything he starts and is terrible at his school work. Tired of seeing him give up at everything and continue to perform so poorly at school, his childhood friend Maiko Yukino shows Reiji the virtual reality game called Dragon Drive. It is a fighting game in which players and their dragon partners face off within a virtual reality city. Reiji's general lazy personality and lackluster school performances lead him to gain a seemingly equally lazy small dragon whom he calls Chibi. Only later do both of their true strengths show as Chibi, despite being small and sleeping in his first appearance, turns out to be the rarest dragon in the game, a discovery which leads Reiji and his friends to another world called Rikyu.
