There are four phases of human existence. From conception to birth is called Phase A. From birth to death is called Phase B. From death to disappearance of the corpse is Phase C. And last, remnant after the death, separate from the corpse, is referred to as Phase D. In this, the very first chapter in Phase D sci-fi visual novel series, the protagonist with the ability to see Phase D which is otherwise invisible to other people is Ayana Fujishiro. Ayana lost her left arm in an accident, and the strange sensation followed by an unbearable phantom limb pain. The game plays like any other visual novel with limited player interactivity, containing several different endings, only some of which are happy endings. Player can adjust the on-screen text speed and turn on/off voice individually for each of the characters. [From MobyGames]
