Kujimaru Otori is a fairly successful 25 year old manga author who has fallen on hard times. His so called girlfriend Rika has milked him for 50 million yen before blocking his number, and has left his life in shambles. While resolving himself to try to win her back, a strange (and strangely dressed) foreign woman suddenly appears in Kujimaru's room, claiming to be the long deceased Queen of France, Marie Antoinette. Though understandably skeptical, the "Queen of the Guillotine" soon proves her identity true.
Thus, Kujimaru is roped into a once in a century supernatural tournament, where the "heroic" souls of history's most dangerous women form contracts with the living in order to battle it out for the opportunity to wish for anything their mortal hearts desire. A tournament called "Villainess Ranking"...
