Kaede Nagase, a tall student of Mahora Girls' Junior High Class 3-A with light brown hair, eyes, and measurements of B89-W69-H86, was born on November 12, 1988, into the Koga ninja clan. Despite her parents’ abandonment of ninja traditions, she honed shadow clones and high-speed movement through self-training. Her calm, half-lidded gaze and archaic speech—marked by "-dono" and "de gozaru"—evoke a samurai’s poise. Academically ranked among the class’s lowest as "Baka Blue" of the Baka Rangers, she mentors youths like Fuka and Fumika in the Strolling Club. Her discovery of Negi Springfield’s magical secret cements her as his strategic ally against foes such as Kotarou and Fate Averruncus, showcasing tactical brilliance. Mastery of Shukuchi speed, Kage Bunshin, and weapons like kunai and a giant shuriken define her combat style. During the Mahora Fighting Tournament, she forces Colonel Sanders to unleash his artifact for victory. A rivalry with Mana sparks after their unresolved festival duel, later fueling humorous yet competitive clashes. As part of Ala Alba in the Magical World, her provisional pactio with Negi yields *Tengu no Kakuremino*—a cloak granting invisibility and extradimensional access, pivotal for stealth missions. Confronting Fate’s shadow mage and Quintum, she survives due to Cosmo Entelecheia’s restraint. By the story’s end, she gains spatial traversal to instantly aid classmates, blending ninja tradition with magical adaptability. Outside battle, she relishes pudding and avoids frogs, contrasting her disciplined guardian role with personal quirks.
