Tsuina Takiguchi carries a curse: misfortune falls on anyone she falls in love with. When she loses her heart at first sight to Souzaemon Mikado, an exorcist a year ahead of her, she refuses to treat the curse as a reason to keep her distance, and the wandering exorcist Noriyuki Izuna takes her on as a trainee in Kyoto. This side story fills in Tsuina's own path into exorcism, ahead of her appearance in the main Ga-Rei manga.
