arisaka hatsune

Hatsune is Kazuki's older sister, always attempting to bring Kazuki and Yuuji closer together, often unintentionally placing them in awkward and risqué situations. It seems she finds humor in these incidents (and the ensuing arguments). She is a school favorite, with numerous clubs vying for her membership. Hatsune excels in all areas, whether it's cooking or sports, and she is notably well-endowed. She enjoys teasing her younger sister by highlighting how captivated Yuuji is by her figure. Hatsune often indulges in cosplay at home and can sometimes be intimidating to those around her. Unlike her younger sister and Marie, Hatsune has no fear of insects or anything else. However, her true concern lies with her sister's health. When Kazuki caught a cold, Hatsune became comically clumsy and struggled with cooking. Occasionally, and somewhat sarcastically, she appears to show an unusual interest in her younger sister.
