Chiaki Kounoike  

, 鴻ノ池 千秋

Bob's girlfriend has an open mind and does not object to his street-fighting with Souichiro. However, after learning about Maya and Mitsuomis relationship, she begins to believe that Mayas ego is the source of everyone else's misery. When Bunshichi explains the full story, Chiaki decides to support the Juken Club despite her initial reservations, believing that Mayas stubbornness caused the past events. Additionally, it appears that Chiaki enjoys having sexual intercourse with Bob and frequently asks him to quit school so they can have sex and sleep until noon.
