Manga by author Sakaki Kenji

Haiba Sumio is a student at a Tokyo High School with an interesting ability... He occasionally falls asleep and wakes up with premonitions of the future written out on his "Dream Diary". With this ability, Sumio helps out people in trouble before anything bad happens, until one day when his peaceful life completely changes.

There was an urban legend about "The Depths of Tokyo", the place where all sinners go!? Sinners there will be judged ruthlessly and cruelly!..
