Sakura Miharutaki is a third-year student at Hyakkaou Private Academy, born into a prominent Japanese family. She previously chaired the Beautification Committee before Midari Ikishima and served as a council member in the Full-Bloom Society (Zensakikai), led by her fiancé Aoi Mibuomi. Their engagement was arranged by their families, but Sakura developed genuine affection for Aoi during their time together since middle school. She dedicated herself to becoming a worthy partner for his ambitions. Sakura maintains a stern, serious demeanor and seldom smiles. Regarded as honest, distinguished, and duty-bound, she blends analytical precision with underlying kindness. Midari Ikishima once cautioned that Sakura's inflexibility could cause her to "snap." She excels at detecting cheating during gambles and strategically weaponizes opponents' tactics against them. Despite her composure, she reveals vulnerability concerning Aoi, displaying jealousy when he recruits Mary Saotome into Full-Bloom and visible anguish when he emotionally rejects her. Physically, Sakura has long dark-blue hair tied in a ponytail with a white ribbon, blue eyes, and a traditionally graceful appearance. She wears Hyakkaou's standard female uniform: a red-trimmed black blazer, white dress shirt, black tie, and brown loafers. Early manga art depicted her as slender, while later illustrations and the anime highlight a curvier figure. Her story shifts dramatically after Aoi publicly humiliates her for losing a gamble against Mary Saotome. Though Aoi sustains their engagement for familial advantage, Sakura recognizes his lack of love. This betrayal sparks her transformation: she resigns from the Beautification Committee, allies with Sachiko Juraku, and schemes revenge against Aoi. Later, she directly contacts Mary to collaborate against Full-Bloom and participates in a pivotal gamble against Soutarou Ibuki. She wins this match while advising Soutarou to claim his independence, revealing her complex morality and enduring empathy even toward rivals. Her journey evolves from unwavering loyalty to strategic opposition against Aoi’s ambitions.
