On the outside, she is a cute and outgoing girl who is playful with her friends, especially [Keiki](https://anilist.co/character/135801/Keiki-Kiryuu). She can sometimes be childish and jealous when Keiki is around other girls, especially [Sayuki](https://anilist.co/character/135802/Sayuki-Tokihara). She does not get along with Sayuki and is always picking on her and the same goes both ways.
~! However, on the inside, Yuika is actually a huge Sadist/Femdom. She wants to dominate Keiki and wishes for him to become her slave, the polar opposite of Sayuki. !~



After cleaning the Calligraphy Club room one afternoon, Kiryuu Keiki found a love letter addressed to him on the club's desk. Eager at the possibility of finally getting a girlfriend, he opens the envelope only to find the words, "I like you" along with a pair of the sender's panties. 

With only these panties as evidence, Keiki narrows down the identity to the four girls who helped him clean the club room that day: Tokihara Sayuki the lazy third-year president of Calligraphy Club, Koga Yuika a library committee member of foreign descent, Nanjou Mao, Keiki's slightly tsundere fellow classmate, and most awkwardly, Kiryuu Mizuha, Keiki's clean freak of a younger sister. Among at least three of these girls, Keiki believes is the one who left him the letter and their panties so with determination in his heart, he sets out to uncover which of these seemingly unorthodox ladies will become his girlfriend!
