 In North America, the full-color edition began serialization in the March 2011 issue of Yen Press' "Yen Plus" online magazine, and ran until the July 2011 issue.The volumes were later released in two hardcover omnibus volumes on November 22, 2011 and December 17, 2013.Shortly following the inception of the series and before it was licensed for distribution in English, the manga became popular enough in English via scanlation to draw the attention of the creators, who included a message in English within the magazine's printing of the fifth chapter that requested readers to buy the original manga when it is available.
