In 2007, Seven Seas Entertainment licensed the manga for North American distribution under the title "Nymphet." However, controversies surrounding the mangas content led to the cancellation of the project. However, in 2016, Digital Manga Inc. launched a successful Kickstarter campaign to publish the series in 5 omnibus volumes. It is set to be released in October 2017.
