Madoka Kugimiya is a 160 cm tall, 72.6 kg human student in Mahora Academy's Class 2/3-A, possessing dark violet hair, grey eyes, and AB blood type. Born March 3rd under the Pisces sign, she serves in the Mahora Cheerleader Club alongside Misa Kakizaki and Sakurako Shiina, acting as the group's serious disciplinarian who actively prevents trouble, especially from Sakurako. Her personality blends a strong sense of responsibility with personal insecurities. She enjoys gyuudon, silver accessories, and Western music like Avril Lavigne, but dislikes playboys and feels self-conscious about her husky voice, which becomes a recurring fixation. Classmates sometimes call her "Kugimi," a nickname she dislikes. During the Kyoto school trip, she develops a brief crush on the teenage Kotarou Inugami. Madoka demonstrates fierce protectiveness towards friends, notably encouraging Ako Izumi's confidence, though this backfires when her pressure leads Ako into a dangerous public confession. In the "Mars vs. Mages" competition, an early robot stripping beam eliminates her by destroying her clothes. She consistently participates in class activities, including the school festival and Live Mahora Concert. During the *Anime Final* film's climax, her role expands. Following the Magic World conflict and facing mandated memory erasure for Class 3-A graduation, Negi Springfield must choose one permanent Pactio partner. Madoka is considered alongside Sakurako and Misa. She is ultimately chosen as one of Negi's partners and aids in preventing Mars from colliding with Earth. In the epilogue timeline, Madoka works as a government official in elevator customs. She finds the job demanding but appreciates Mahora's urban development allowing local leisure. She retains her attraction to individuals with black hair and dog-like ears. Her alternate timeline appearance in *UQ Holder!* shows her reuniting with Sakurako and Misa to locate Evangeline and discuss Negi's battle against the Mage of the Beginning. Her Pactio manifests as an energizing cheer power when formed collectively with Misa and Sakurako. In the *Negima!?* anime adaptation, she exhibits transformative abilities: becoming a black panther during the "Suka incident." Her cosplay form features a prisoner outfit with a chained metal sphere and hammer, while her armored form references Saki Asamiya from *Sukeban Deka*, wielding a metallic yo-yo.
