5 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. English dub featuring an all-star cast takes this story of star-crossed love on an interplanetary scale.
