Ouri Kagami (花神旺里 also nicknamed Hanagami) is a normal high school student who is currently the Contracted Monk of Makina Hoshimura from the Kōgon Sect and the adopted brother of Keisei Tagami who raised him at the Dai-Rin Orphanage, which is right across the Sekku Temple. He is also friends with four of his fellow classmates: Hiroshige, Sumitori, Mizuki and Nozomi.
Ouri made his first appearance in chapter 3 of the manga in Ikai High School when Hiroshige and Sumitori were discussing him about a previous incident which occurred in the man eating house were a group of students, including Nozomi got suddenly attacked by a group of shikabanes. Throughout the first half of the manga, Ouri would always get involved with a few incidents concerning shikabanes because of a mysterious black cat who randomly appear to talk to him and thus leading him to follow it. He also worries about Keisei whenever he finds him in the Dai-Rin Orphanage with frequent injuries which led him to gradually discover the truth of Keisei's secret. In chapter 9, after Keisei and Makina finished their battle with Izuwa (also known as Mr. Whisper) from the Shichisei, Ouri would finally encounter Makina for the first time and therefore causes him to worry about his brother even more. Later in chapter 14, during his sixteenth birthday, Keisei would ultimately get killed at the hands of Akasha and Shimen from the Unclean Bunch organization. Before his last breath, Ouri would receive his transferred contract in order to prevent Makina from reverting to a rogue shikabane. After Keisei's cremation, Ouri would officially be declared a contracted monk of Makina by the Kōgon Sect and undergo physical training at Mount Goryo with Kanechika Umehara and Touma Sawamiya so he could avenge his brother and prepare the upcoming war against the Unclean Bunch organization, which is led by the Unholy King, Sugamimaen.
