The Boogiepop series (ブギーポップシリーズ, Bugīpoppu shirīzu) of Japanese light novels is written by Kouhei Kadono and illustrated by Kouji Ogata.

By studying him, the Towa Organization was able to create synthetic humans, people who have been artificially enhanced with special abilities.

The mission of the Towa Organization and its agents is to find and kill MPLS, people who are more evolved than others and possess special abilities.

Boogiepop speaks in an archaic manner, and seems fond of whistling the prelude to Wagner's Die Meistersinger von Nürnberg.

An ordinary, happy school girl at Shinyo Academy, Miyashita is in love with her boyfriend, Keiji Takeda, and close friends with Suema.

Unknown to most, she was hospitalized as a child, and this saw her life change, though even Miyashita herself does not seem to know the truth of what happened, and was simply told that she had been possessed by a kitsune.

Unknowingly, when the world is in trouble, she carries a Spalding sports bag containing the effects of Boogiepop, her alternate personality.

Known as the Fire Witch to many, Kirima has made few friends due to the way she distances herself from others: she knows that she is too dangerous for 'normal' people to associate with.

As a result of a childhood trauma, Suema has developed an unusual fascination with criminal and abnormal psychology, as well as the desire to not let anything occur around her without her knowing.

As a result of this, she desperately seeks the truth about the unexplained events happening in her city, and meddles with forces best left untouched.

Rose Bridges of Anime News Network reviewed the first four episodes, giving them an A− and writing, "If Boogiepop and Others can keep this up, it might be a truly stellar adaptation.

"[24] Brittany Vincent of Syfy wrote that "if you're in the mood to kick off a lengthy journey through a sometimes obtuse but wholly satisfying narrative that explores the supernatural, split personalities, and plenty of allegory, give Boogiepop and Others a chance.
