Nightmare Detective

Kagenuma Kyoichi is a dream analyzer with the very unwanted "gift" of being able to hear the thoughts of those around him, as well as the ability to enter peoples' subconscious while they dream. Kyoichi's rare talents make him highly sought-after in his field, but they also render his life unbearable. He can heal broken minds, but he would just as soon kill himself as ever help another person again.
A string of suicides occurs, connected by a distinctly unnatural thread -- the deceased slashed themselves with razors while they slept. Enter Kirishima Keiko, a homicide detective fascinated by the case. She hunts Kyoichi down and essentially forces the death-tripping clairvoyant to help her investigate.
