High school girl Ayazuki Mei crosses paths with the illusionist Charlie on a night when the moon burns red, and his trick slides her back to the Meiji Era—a version of Tokyo haunted by Mononoke and populated by real historical figures at a Rokumeikan party she was never invited to. Among those waiting are Ogai Mori, Shunsou Hishida, Otojirou Kawakami, Kyoka Izumi, Fujita Goro, and Yakumo Koizumi. As she interacts with these men, her dormant ability to perceive Mononoke—Tamayori—awakens, deepening every bond she forms. Whether she ever finds her way home, or wants to, is the question her heart will eventually answer.
