Tokyo, end of the 20th Century. K has taken on a justice-seeking alter ego who the media have baptised "Four Eyes". The police are hunting him down as a killer, but behind his strange thick glasses, he shoots to miss. A teenaged girl, Hinano, discovers K's hidden identity, and even though she empathizes with the ideals that have driven him to this dangerous behaviour, she tries to bring out the gentle young man who existed before he turned to vigilante justice.
