Sakurako Shiina attends Mahora Academy as student number 17 in Class 2/3-A. Born June 9, 1988, she is a Gemini with blood type B, standing 164 cm tall with measurements of 83-56-79 cm. Her hair and eye colors shift across adaptations: pale red hair with hazel brown eyes in the manga, OVAs, and *ANIME FINAL*; red hair with magenta eyes in the *Mahou Sensei Negima!* anime; blonde hair with blue eyes in *Negima!?* and other versions. As the cheeriest member of the cheerleading trio alongside Misa Kakizaki and Madoka Kugimiya, she participates in both the Mahora Cheerleading and Lacrosse Clubs. Her hobbies include karaoke and doting on pet cats Cookie and Biscuit, though she dislikes the "black stuff" her cats discover in the kitchen. She often peppers her speech with "nya," a habit likely picked up from her feline companions. Having known Asuna Kagurazaka and Ayaka Yukihiro since elementary school, Sakurako understands their personalities and conflicts intimately. She frequently gambles, winning high-stakes bets through uncanny intuition—like being the only one to wager on Nodoka Miyazaki during the "Kiss Negi Operation" or predicting her class’s top exam scores. This supernatural-level luck guides her group through fog to a vital gateport during their Magic World journey, earning comparisons to "winning the lottery" from Donnette McGuiness. Classmates dub her "Mahora’s Lucky Mask" or a "Daimyoujin" (Shinto demigod) for this trait. In the Magic World arc, Sakurako journeys with Ayaka’s group to England and tries following Ala Alba through a gateway. Though separated during transit, she reunites with classmates when Zazie transports everyone to Magicus Mundus to awaken Asuna. During the "Mages vs. the Martian Attacks," enemy beams leave her depicted in her underwear. By the epilogue, Sakurako leverages her intuition at a securities company, swaying global economics to indirectly support Negi Springfield’s long-term strategies. She prioritizes days off for friends alongside work. Fate Averruncus monitors her luck-based power for potential positive uses. In non-canonical stories like *Negima!?*, Sakurako and her cheerleader partners often finish each other’s sentences as a unit. During the "Suka incident," she transforms into a dog—contrasting Makie Sasaki’s monkey form, nodding to Japanese folklore’s dog-monkey rivalry. Her Pactio artifact here is a stick topped with a small tree.
