Makoto Higuchi is Seria Morino's classmate, easily identified by her dark brown twin ponytails and black eyes. Her school attire consists of a red uniform top, a black skirt, long white or beige socks, and brown shoes.

Openly opinionated, Makoto frequently voices skepticism about Seria Morino's aspirations, particularly her dream of becoming a stage actress. Drawing from her own experience failing an audition for the demanding Super Material Theater, Makoto believes Seria lacks the necessary talent and directly advises her against pursuing acting.

Despite this skepticism, Makoto maintains a close friendship with Seria and consistently aims to support her. Their interactions, however, carry underlying emotional complexity, as Makoto's feelings for Seria extend beyond friendship, a romantic interest consistently hinted at though not explicitly confirmed.

Primarily, Makoto serves as a grounded counterpoint to the main characters' theatrical ambitions, offering perspective on the challenges of theater work. She does not join any performing troupes herself but remains connected to that world through her relationship with Seria.
