Madoka Kugimiya, a human student in Mahora Academy's Class 2/3-A, stands 160 cm tall with dark violet hair and grey eyes. Her blood type is AB and her birthday is March 3rd, making her a Pisces. Known for her serious demeanor, she serves as one of three members in the Mahora Cheerleader Club, frequently keeping fellow cheerleaders like Sakurako out of trouble. Her preferences include gyuudon from Matsuya, silver accessories, and Western music—Avril Lavigne being a recent favorite. She dislikes playboys and expresses dissatisfaction with her own husky voice. The nickname "Kugimi," used by classmates, displeases her. At the school festival, she develops a small crush on Kotarou Inugami after he appears in an aged-up teenage form. Demonstrating strong protectiveness towards friends, especially the shy Ako Izumi, Madoka encourages Ako to be more confident. This leads to a risky situation during the Live Mahora Concert where Madoka's insistence that Ako confess feelings for "Nagi" nearly results in Ako being shot; disaster is averted when Ako only asks for Nagi's email address. Madoka participates in the "Mars vs. Mages" game, becoming one of the first casualties when robots' strip beams blast off her clothes. Later, she joins the "Ala Alba" brigade with classmates to assist Negi Springfield in saving Nagi and confronting the Mage of the Beginning. Following these events, she works as a government official handling elevator customs—a demanding job, though Mahora Academy's development allows her leisure activities without extensive travel. She exhibits a noticeable attraction to individuals possessing black hair and dog ears. In the *Negima!?* alternate continuity, Madoka transforms into a black panther during the "Suka incident." Her cosplay form features a prisoner outfit with a metal sphere attached to her leg, wielding a hammer. Her armor form references Suki Asamiya from *Sukeban Deka*, utilizing a metallic yo-yo in combat. Within the *Mō Hitotsu no Sekai* OVAs adapting the "Journey to the Magic World" arc, she travels with Ala Alba to Mundus Magicus. After forced transportation scatters the group across this Magic World, Madoka becomes separated from Negi and the others; efforts focus on reuniting the scattered classmates, though her specific activities during displacement remain undetailed. During events leading to the memory-erasure mandate for Class 3-A regarding Negi and magic, Madoka speculates about who will become Negi's partner, discussing this with fellow cheerleaders Sakurako and Misa. She is later selected as one of Negi's partners and participates in efforts to prevent Mars from colliding with Earth. In the *UQ Holder!* timeline set after Asuna's return, Madoka appears alongside Sakurako and Misa to locate Evangeline and discuss the ongoing battle between Negi and the Mage of the Beginning.
