Blue Drop (ブルー ドロップ) is a Japanese science fiction yuri manga created by Akihito Yoshitomi. A Blue Drop anime series directed by Masahiko Ohkura and produced by Asahi Production and BeSTACK aired in Japan between October 2 and December 25, 2007 under the title Blue Drop: Tenshitachi no Gikyoku (BLUE DROP ～天使達の戯曲～). All the Blue Drop stories revolve around a war between humanity and the Arume (アルメ), an alien race consisting solely of women.
Five years ago, something horrifying happened on Kamioki Island. Something so nightmarish that it stripped all memory from Mari Wakatake’s mind even as it left every other human on the island dead in its wake! Now enrolled against her will at an isolated girl’s academy, Mari is unaware that hidden eyes are watching her, waiting for her memory to return. Buried in her psyche is the most terrifying secret of all: while Mari was the only human who lived, she may not have been the only survivor! As something in a female skin invades Kaihou Academy, Mari’s only hope may lie in a strange girl to whom she is inexplicably drawn yet cannot trust.[sociallocker]
