Anri Misugi joins as the fifth magical girl club member, wielding innate magic that activates without transformation or items. Her core ability manifests tangible effects from written words or drawings using ordinary tools—sketching "umbrella" or "light" conjures functional objects, strictly limited to physical creation, not reality alteration.

She cultivates a princess-like persona marked by vanity, arrogance, and assertiveness, consistently adorned in gothic Lolita attire. This image starkly contrasts her reality: she hails from a large, impoverished family crammed into a modest one-story home where everyone sleeps on the floor. Anri lacks a private room. Nevertheless, she deeply cares for her younger triplet brothers, actively securing food aid for them and mastering babysitting and household chores through their care. She avoids openly acknowledging her family's persistent poverty.

Within the club, Anri exhibits overt, persistent romantic infatuation with Tsukasa Takamine, showering her with effusive praise and physical affection while aggressively confronting perceived rivals—even crafting curses against them. Tsukasa tolerates but does not return these advances. Anri also clashes regularly with the equally loud Makoto, though they remain friends. Conversely, she shows protectiveness towards Misao Shinohara, initially backing Misao's choice to join the witches and reprimanding Monta when believing he upset Misao.

In combat against elite foes like the Chief Sorceress's team or experienced witches like Itoki, her effectiveness proves limited, underscoring her magical inexperience despite potent innate power. During the finale, she gains access to light magic through the club's collective bond with Sasami, augmenting her existing abilities. Washu provides her magical outfit—a bright yellow jester design distinctly different from her usual gothic style.

She is one year older than most club members, attending sixth grade while others are in fifth. Her blood type is AB, and her height is 140 cm.
