The wraparound jacket band on the seventh compiled collector’s edition book volume of Robico’s My Little Monster (Tonari no Kaibutsu-kun) manga revealed on Tuesday that the manga has 6.1 million copies in print.
Robico launched the manga in Kodansha’s Dessert magazine in 2008, and ended it in June 2013.
The manga inspired a television anime series that ran in 2012.
Crunchyroll streamed the series as it aired in Japan, and NIS America released the series on Blu-ray Disc and DVD in North America in June 2015.
