This year's 19th issue of Shueisha's Weekly Young Jump magazine revealed on Thursday that Yasuhisa Hara's Kingdom manga has 30 million copies in print. The manga had 28 million copies in print as of January.

Hara's historical manga centers around the slave boy Xin and his dream of becoming a great general for the state of Qin. Xin helps Ying Zheng, the young Qin king who shares his desire to unify China, rise to power within the state. Xin does all he can to become a superior commander of an army capable of defeating the Seven Warring States.

A real-life escape game event in collaboration with the manga opened in Japan on March 24. The manga is also inspiring a smartphone game this summer. Shueisha began streaming a live-action short based on the manga last April to mark the series' 10th anniversary.

The record-setting manga launched in Weekly Young Jump in 2006. Shueisha released the 45th compiled book volume in Japan on January 19, and the 46th volume will ship on April 19. A television anime adaptation premiered in 2012, and a second season premiered in 2013. Funimation streamed the series in North America and released both anime on DVD last year.
