Victorian London in the 19th century, lit by gas lamps blurred by the fog. Our hero visits the Black Museum, a crime archive in Scotland Yard and the "curator" of historical horrors. She requests to see the curator's red boots... the remains of a mysterious incident that took place at a ball hosted by the Queen. The woman then recounts the story of a very strange swordsman. The long-awaited latest installment in Kazuhiro Fujita's popular "Ushio-Tora" and "Karakuri Circus" series!
