Art historian Yoko Akiko came to Koyasan and wrote an essay on the subject of "Prohibition of Women and Female Criminals". When she stopped at the library, she happened to find a document describing the monk Sumitomo, who was expelled from Koyasan by order to touch a female criminal. Yoko appeared in the form of Aizen Meio in the form of Sumiken, and it is said that he was "immediately troubled". I looked for "Seikei" written by Sumiken, but I couldn't find it. Because of Terei's obstruction, it is said that this monk has never committed a crime for fifty years. One day, Yoko met Sumiken and Trey in the time and space of Koyasan, where he visited again. Yoko stared at the two monks who had been able to forgive each other for many years. Sumiken and Yoko broke up and promised to meet again. Later, Yoko who visited the library finally found the "Rikakei" he was looking for.
