Plot
Two teenagers from childhood, Shiro Amachi and Masumi Izumi, who were swallowed by a dragon on their flight to China during their junior high school trip. They suddenly find themselves in China in the year 207 during the prelude to the Three Kingdoms period, at the start of the campaign leading to the Battle of Red Cliffs. As they learn how to survive, in part through Shiro's knowledge of the historical novel "Romance of the Three Kingdoms" and progressing aptitude for martial arts, they become known as "Dragon Leader" and "Dragon Princess," working for Liu Bei and Cao Cao, respectively.
