The main character of the story, she currently resides in room #4 of the Ayakashi Kan and is the master of Miketsukami Soushi. Ririchiyo is constantly in distress about not being able to communicate with people properly and decided to move to the Ayakashi Kan in order to be alone. She later befriends Karuta and Watanuki who both attend the same school and live in the Ayakashi Kan. She is the first character in Japanese anime and manga to be classified as a tsunshun instead of tsundere because she gets depressed (shun) instead of getting modest (dere) after behaving in a conceited manner.
