Umineko no Naku Koro ni EpisodeX Rokkenjima of Higurashi crying (うみねこのなく頃に EpisodeX ROKKENJIMA of Higurashi crying) is a manga-exclusive series by Ryukishi07 and drawn by Yuki Hiiro. Essentially a cross-over between Umineko no Naku Koro ni and Higurashi no Naku Koro ni, it features characters from both series. The series was serialized on Dengeki G's Festival! magazine by ASCII Media Works, a brand company of Kadokawa, between January 26, 2009 (shortly after the release of Alliance of the Golden Witch, notably) and February 23, 2011. Two volumes of EpisodeX were released: the first on February 26, 2010 and the second on April 27, 2011 under ASCII Media Works' Dengeki Comics imprint.
