OVA
Description
Setsuna Sakurazaki joins Class 2-A's tropical getaway in the "Negima!? Spring OVA." She attends expressly as Konoka Konoe's guardian. Her primary interactions involve visible embarrassment and internal discomfort at Konoka's choice of swimwear, reflecting her protective instincts and personal unease. She participates in beach activities alongside Konoka and Asuna Kagurazaka, maintaining her reserved demeanor while fulfilling her duty. The OVA does not show her employing her swordsmanship, demon heritage, or pactio artifact.

Born a half-demon (hanyō) to a human mother and a crow demon father, Setsuna's albinism manifested as white wings. Her tribe deemed this a bad omen, resulting in her exile. Discovered by Eishun Konoe, she was adopted and trained in swordsmanship at his Shinmei-ryū dojo in Kyoto, where she was assigned as Konoka's childhood companion and protector. A pivotal incident occurred when Konoka fell into a river; Setsuna's perceived failure to rescue her promptly led to intense self-blame. Despite Konoka's forgiveness, Setsuna emotionally distanced herself, reverting to formal terms like "Ojō-sama" instead of the childhood "Kono-chan" and focusing solely on silent protection.

Initially blending into Mahora Academy's Class 2/3-A, her role expanded during the Kyoto field trip when Eastern mages targeted Konoka. Setsuna allied with Negi Springfield to defend her, battling rivals like Tsukuyomi and forming a probationary pactio. This pactio artifact, Sica Shishikushiro, allows her to summon and telekinetically control multiple wakizashi blades. Confronting the demon god "Ryoumen Sukuna no Kami," she revealed her hanyō form to save Konoka, violating her clan's exile law if humans witness her true nature. Negi intervened, preventing her departure and facilitating reconciliation with Konoka. This marked a turning point; Setsuna gradually resumed calling her "Kono-chan" and began forging friendships with Negi and Asuna.

Her development continued through subsequent arcs. She participated in the Mahora Festival's martial arts tournament, facing opponents like Asuna and Evangeline. Stranded in an alternate future created by Chao Lingshen, she aided the group's return. Later, she joined Negi's brigade, Ala Alba (White Wing), journeying to the Magic World (Mundus Magicus). An attack by Fate Averruncus scattered the group upon arrival. Setsuna protected Konoka from petrification using her wings but was separated alongside Asuna. They later reunited with Negi in Ostia after witnessing his battles. Her combat skills and loyalty remained central throughout, including clashes with Tsukuyomi and the Black Hounds bounty hunters.

Her personality blends stoic professionalism with deep-seated loyalty and vulnerability. She frequently denies romantic feelings for Konoka despite subtextual hints and accidental admissions, causing comedic misunderstandings. Her crow demon heritage grants flight via wings and minor magical abilities like creating shikigami. She conceals her natural red eyes and white hair with contacts and dye, a secret highlighted by Evangeline. Her primary weapon is the inherited nodachi "Yūnagi" from Eishun Konoe.
