Makoto Hozumi is the shortest member of her magical girl club at 137 cm, a trait fueling her expressed insecurity. To compensate, she frequently adopts a loud, brash, and assertive demeanor consistent with her tomboyish nature. This headstrong personality often causes clashes with fellow club member Anri.

Her specialized magic, curiously categorized as "gravity manipulation," allows her to shrink or enlarge herself and objects at will, primarily affecting size without significantly altering mass or gravity. Using this power requires consuming substantial amounts of milk for energy, leading to frequent restroom breaks. Despite her ability, her default height remains unchanged, indicating limits to permanent alteration or maintaining a believably different size. Her proficiency in size magic was surpassed by another magical girl with greater mastery. Like her clubmates, she also gained the capacity to channel light magic through her friendship with Sasami.

Socially, Makoto shows a pronounced interest in interacting with boys and obtaining their contact information, a trait highlighted during early club outings that draws teasing from Anri. She expressed attraction toward Amitav twice, describing him as "cute" despite his unconventional behavior; this attention provoked noticeable jealousy from Sasami. Observational context suggests she is the only club member not depicted as particularly close to any single individual, often shown alone while Tsukasa pairs with Anri and Misao with Sasami, though this dynamic doesn't appear to distress her like Misao's experiences.

Her birthday is March 11th, her blood type is Type B, and she bears a slight resemblance to Eimi Date from *Magical Project S*, another short-haired brunette magical girl characterized by bluntness and assertiveness. However, Makoto's focus centers on her height, contrasting with Eimi's dedication to enforcing rules.
