Miku Takeshita and her family have moved from Japan to live in the UK, but unfortunately the family's enemy demons have followed them... Miku knows she's in trouble when her new supply teacher turns out to be a Nukekubi - a bloodthirsty demon who can turn into a flying head and whose favourite snack is children. That night, in a raging snowstorm, Miku's little brother Kazu is kidnapped by the demons, and then it's up to Miku and her friend Cait to get him back. The girls break into their snow-locked school, confronting the dragon-like Woman of the Wet, and outwitting the faceless Nopera-bo. At last they come face to face with the Nukekubi itself - but will they be in time to save Kazu?
