The North American publisher Digital Manga has confirmed with ANN that it has canceled its plans to publish Magical Girl Lyrical Nanoha StrikerS, Masaki Tsuzuki and Kôji Hasegawa's manga adaptation of the third season of the Magical Girl Lyrical Nanoha anime franchise. Digital Manga announced its acquisition of the license at Anime Expo in 2008, but never released any of the series. According to a Digital Manga representative, the series' release was canceled "a while ago."
Digital Manga could not comment on the reasons behind the cancellation but confirmed that the rights to the manga had reverted back to its Japanese publisher, Gakken.
