Kyōka Izumi is a young playwright who has moved from the countryside to Tokyo, having dropped out of the Hokuriku Eiwa School to pursue a career in writing for the stage. He lives as a live‑in pupil under his master, the novelist Ozaki Kōyō. A lifelong collection of rabbit‑themed trinkets began after his mother told him that gathering items related to the opposite zodiac sign would bring good fortune; the stuffed rabbit that perches on his shoulder is a tsukumogami, a type of spirit born from a treasured object, and serves as a keepsake from his deceased mother. Despite a delicate, almost boyish appearance, Kyōka is highly nervous, prone to sharp‑tongued remarks, and openly contemptuous of inefficiency, yet he harbours an array of intense fears: dogs, thunder, and a near‑obsessive germophobia that makes him fastidious about cleanliness. He is a tamayori, meaning he can see and interact with the mononoke, or spirits, that appear in the world after dusk. In the story of Hanakagami no Fantasia, Kyōka’s emotional walls gradually lower as he grows closer to the time‑travelling heroine, Mei Ayazuki. He becomes protective of her, even to the point of recklessness: when Tōsuke Iwasaki loses control, Kyōka shields Mei from the resulting attack and sustains a fatal wound, only to be revived by the snake spirit that had once impersonated Tōsuke’s mother. This near‑death experience, along with the revelation that he and Mei had met as children through a magical mirror, deepens his trust and confirms his love for her. By the film’s end, he has chosen to remain with Mei in the Meiji era, setting aside his earlier prickly independence for a future built on mutual affection. His primary abilities stem from his tamayori nature, which allows him to perceive spirits and maintain a bond with the rabbit spirit that accompanies him, and his own determined will to protect those he cares for.
