Flying Witch manga volume 13 features story and art by Chihiro Ishizuka.

Preparations for the Great Sabbath, a worldwide witchy event held once every twenty years, have kicked into full gear, and to Makoto's delight, Aomori is on the list of candidate host cities. She, Akane, and Maria try to amplify its appeal to the judges who have come to tour the city—only to be blindsided by a very sneaky sabotage campaign. It also comes to light that a missed milestone has put Chinatsu in dicey spiritual territory. Now, it's up to Makoto to save her soul!
