Makoto Hozumi serves as the third member of the magical girls club. Her unique magical ability manipulates the size of herself and other objects at will, classified as gravity manipulation despite its specific focus on size alteration. This power demands significant milk consumption to maintain energy, resulting in frequent restroom visits. Standing at 137 centimeters, she is the club's shortest member. Her birthday is March 11, and she possesses type B blood.

Makoto shows a keen interest in the opposite gender. On the club's early outings, she actively seeks interactions with boys and attempts to collect their contact information, a tendency lightly teased by fellow member Anri. She also expresses romantic attraction toward Amitav, an enigmatic being from the magical world, calling him "cute" despite his unconventional demeanor; this interest has been noted to provoke jealousy in Sasami.

Within the club's social structure, Makoto isn't portrayed as particularly close to any single member. While others form natural pairings—Tsukasa with Anri, and Sasami with Misao—Makoto is often depicted alone in narrative contexts and promotional materials, suggesting friendships with all members but lacking the same depth of connection as the others. Unlike characters distressed by isolation, she exhibits no particular concern about this dynamic.

Visually, Makoto has short brown hair cut to neck length, purple eyes, and frequently sports multiple ahoge. Her standard outfit is a shirt and skirt. A noted trivia point highlights her slight resemblance to Eimi Date from Magical Project S, sharing similar blunt, loud, and assertive personality traits as short-haired brunette magical girls, though their focal concerns differ: Makoto exhibits preoccupation with her height, while Eimi concentrates on enforcing rules.
