Zangou no Houkiboshi

1914. Birmingham, England. War is on the horizon.
      Monica, a witch, soars through the smoky skies astride a mechanical broomstick. As the conflict that will come to be known as the First World War engulfs the world, witches find themselves swept up in its chaos: manipulated, exploited, and fighting to survive on their own terms.
