Mizuho Kusanagi launched the series in Hakusensha's "Hana to Yume" manga magazine on August 4, 2009. The series has been collected into 35 bound volumes. On October 9, 2015, North American manga publisher Viz Media announced at their New York Comic Con panel that they have licensed the manga and will begin releasing it in summer 2016. The series went on hiatus starting with 2016's eleventh issue, on April 25, 2016, due to the earthquakes in Kumamoto, where Kusanagi lives. It resumed in the twelfth issue on May 20, 2016.
