While going through the motions of a normal life, Takagi becomes increasingly obsessed with the corpse of a young woman in his dissection class. Gradually his memories start returning as he realises that the body is that of his dead girlfriend Ryoko. Growing more protective of the body, Takagi also starts experiencing waking dreams of his dead girlfriend, but is Takagi suffering hallucinations as a result of his mental state, or has he found some way of communicating with Ryoko's spirit?
