Hikari Kuroda, a temperamental yet fastidious first-year student in class three, balances a friendly, social demeanor with a distinctively prickly edge. Her unique squid-ring hairstyle and striking green eyes complement her 161 cm frame. Born on November 9, she is the only child of a family running a confectionery store and café famed for its lemon custard pie. Close friendships with Sekai Saionji, Setsuna Kiyoura, and Nanami Kanroji anchor her social life, alongside a lingering crush on Taisuke Sawanaga, a middle school acquaintance also connected to Yuuki Ashikaga and Tanaka.
After relocating to Haramihama and joining Sakakino High, Hikari’s interactions reveal contradictions: though bubbly and outgoing, she harbors disdain for boys, especially Makoto, and displays childish tendencies through whining and nosiness. Her tsundere temperament surfaces in schemes like the Valentine’s Day prank targeting Makoto and Taisuke, and her aborted attempt to leave chocolates for Taisuke. Collaborative ventures include working at Radish café’s Mobile Defense Squad—her vulpine-themed uniform a quirky touch—and managing Sweets Ohara, her family’s second shop, where she reencounters Yuuki and becomes entangled in Roka Kitsuregawa’s mistaken assumptions.
Hikari navigates events like the onsen visit with Kotonoha, admiration for Kokoro’s waitressing skills, and participation in Radish’s squad. Later arcs place her at a bonfire with Taisuke and, controversially, in a prostitution venture alongside Roka and Makoto. Throughout, her identity remains tied to her family’s confectionery legacy, her capricious friendships, and the blend of charm and volatility defining her relationships.
