Shirakiin, Ririchiyo

白鬼院凜々蝶

As the story's main character, she currently lives in room #4 of the Ayakashi Kan and is the master of Miketsukami Soushi. Ririchiyo is constantly distressed by her inability to communicate properly with others and moved to the Ayakashi Kan 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 rather than tsundere, because she becomes depressed (shun) instead of modest (dere) after behaving in a conceited manner.
