An energetic classmate of Kyouya Sato during his freshman year, this short-haired girl remains largely unaware of the deeper complexities behind the "fake boyfriend" arrangement. As a close friend of Erika, she is only privy to the surface-level rumors circulating the school. Although she shares a history with Sato from their first year together, she openly admits that the two have never developed a particularly close or personal relationship.
