When a female student is abducted and on the verge of being raped, Boogiepop rushes onto the scene just in time to save the day. But Boogiepop's new male alter-ego, Akimizuki Takaya, finds himself in the middle of a crime wave with ties going back to the previous owner of the Boogiepop mantle.

A strange silver-hair man, Ameya, helps a young boy, Norio. But no-one seems to see this weird man...

A murder takes place in a locked room, with only one clue: a piece of paper filled with an incomprehensible warning:
? Within three days I will steal the equivalent value of the life of the person who will be in this room?
Two inspectors working for Sircam insurance, Isa et Senjo, think that the culprit is "Paper Cut". But who is this enigmatic murderer?

This prequel to the very popular Boogiepop Phantom series deals with the sudden disappearance of several female students at Shinyo Academy. Are they runaways, abductees or murder victims?

Couple this mystery with the sudden appearance of a mysterious apparition known only as Boogiepop, and even more questions arise in the mind of Keiji, a student who can see and converse with the strange spectre.

Who or what is Boogiepop? Is he responsible for the abductions or is he trying to stop them? Why does he have the appearance of Keji's girlfriend, Touka?
