Setsuna Sakurazaki, a hanyō born between a human mother and a crow demon father, bears ivory wings that branded her an ill omen among her tribe, resulting in exile. Adopted by Eishun Konoe, she mastered Kyoto Shinmei-ryū swordsmanship and became Konoka Konoe’s sworn guardian, sharing a deep childhood bond. A pivotal failure—unable to stop Konoka from falling into a river—drove her to suppress emotions, enforcing strict professionalism as a protector. Her duties escalated during a Kyoto class trip when she clashed with eastern mages targeting Konoka, revealing her demonic form to save her. Though tribal law demanded exile for such exposure, Negi Springfield’s intervention secured her stay, repairing her bond with Konoka and forging alliances with Negi and Asuna Kagurazaka. A probationary pactio contract with Negi granted her the artifact Sica Shishikushiro, summoning sixteen telepathically commanded wakizashi. At the Mahora Festival, she dueled rivals like Asuna and Evangeline in the martial tournament while unraveling Chao Lingshen’s time-travel scheme. Her vigilance shielded Negi’s team during clashes with Chao’s mechanized forces. In the Magic World arc, she joined Negi’s Ala Alba unit to locate his father in Mundus Magicus. Ambushed by Fate Averruncus, she shielded Konoka from petrification by enveloping her in her wings, though the protective act scattered the group across the realm via an explosive backlash. Reuniting with Asuna, she monitored Negi’s battles and relayed their status. Her evolution saw her cautiously embrace vulnerability, reviving childhood nicknames with Konoka and bonding with peers. Struggles with her demonic identity flared during Evangeline’s provocations, yet her dedication to Konoka never wavered. Training in Wales and ensuing trials cemented her role as a bridge between human and demon realms, balancing duty with self-discovery.
