Midori-chan is a supporting character in the Recorder and Randsell Re anime. She is a classmate and the closest friend of Atsumi Miyagawa, the high school girl who appears much younger than her age. Midori-chan has medium-length brown hair and red eyes, and she stands out among her peers for her mature and sensible demeanor. She often serves as the voice of reason, offering calm, practical advice to Atsumi and occasionally to Atsushi, Atsumi’s younger brother who looks like an adult. Her personality is responsible, caring, and level-headed, directly contrasting with Atsumi’s more impulsive and childish tendencies. Midori-chan acts as a grounding influence, helping the Miyagawa siblings navigate the daily misunderstandings caused by their reversed appearances. She demonstrates strong social awareness and a supportive, almost maternal kindness, always willing to listen and provide guidance. Her primary motivation is to look out for her friend and maintain harmony in their group. While she does not possess any special abilities, her reliability and perceptiveness make her an essential steadying force in the story. Her role remains consistent throughout the series, with no major character development, as she functions as the stable friend who helps keep the comedic situations from spiraling out of control.
