OVA
Description
Kaede Nagase occupies seat 20 in Mahora Academy's Class 3-A. Descended from the Koga ninja clan, her parents did not uphold the ninja traditions, leading Kaede to develop her abilities through self-training. She stands 181 cm tall with light brown hair and eyes, blood type O, and measurements of B89-W69-H86. Her birthday is November 12, 1988.

Personality-wise, she typically displays a gentle, calm, and easy-going demeanor, often seen with her eyes nearly closed. Her speech incorporates the archaic suffix "de gozaru" and the honorific "-dono." Academically, she ranks among the lowest in her class, earning her the nickname "Baka Blue" as part of the "Baka Rangers." She participates in the Strolling Club alongside Fuka and Fumika, frequently assuming a protective or mentoring role within the group.

Her ninjutsu abilities include techniques like Kage Bunshin (shadow clones), Shukuchi (high-speed movement), and Shukuchi Mukyou (long-distance instant movement). She wields traditional ninja weapons such as kunai and giant shuriken, employing attacks like Bakusa Bakuenjin (Binding Chain Eruption) and Tenma Fukumetsu Bakusa Chimoujin (Demon Annihilation Binding Array). She can alter her appearance to look younger and senses presences within approximately one kilometer. She identified herself as a Koga clan chūnin during the Kyoto rescue mission.

Kaede was the second classmate to learn of Negi Springfield's magical abilities. She aided him in conflicts including the battle against Kotarou Inugami and the Mahora Fighting Tournament, where she fought Colonel Sanders (Albireo Imma). Transported to the future following Chao Lingshen's revelation of magic, she later joined Ala Alba to support Negi's journey to the Magical World. She formed a pactio with Negi, receiving the artifact Tengu no Kakuremino—a cloak granting invisibility and access to an extradimensional space containing a traditional Japanese house. This artifact facilitated group transport and tactical evasion during missions, such as infiltrating Ostia and confronting Fate Averruncus' forces. She engaged Quintum in combat and assisted in rescuing Asuna.

In the epilogue, her capabilities evolved to traverse physical space, enabling immediate intervention when classmates faced danger, underscoring her role as a dependable protector.
