One of Rentarou's girlfriends. She possesses a captivating figure yet maintains impeccable conduct. In reality, however, she is a calculating schemer—though at times, her mind becomes so consumed by romantic fantasies that she gets carried away by her own plots. Deep down, she is earnest and unfailingly considerate toward everyone, not just Rentarou. Her mother is Hahari.

One of Rentaro's girlfriends. She is an "all-around" tsundere girl whose catchphrase is "It's not like I'm [doing/being]...!" Although she has a tough, guarded personality, she also possesses a dependable, big-sisterly nature. While she often plays the straight man—acting as the voice of reason—she also has a surprisingly sensitive side.
