Chiemi Domoto works as an in-between animation inspector at Musashino Animation, a role that places her within the quality control process of the studio's productions. She is a supporting character who appears most significantly in a scene during the twenty-second episode, where she shares a meal and a conversation with her close friend and colleague, Nao Shinkawa. Her appearance includes brown hair worn at neck length and grey eyes, and she is often seen wearing a turtleneck.

Her personality is conveyed primarily through her frank workplace opinions and her perspective as a working parent. She openly admits to disliking fellow employees Tarou Takanashi and Daisuke Hiraoka, expressing concern that her own son might grow up to behave as they do. In a more positive light, she admires Aoi Miyamori and wishes that the studio had more staff members with her reliable and competent attitude. Her motivation stems from a practical understanding of the animation industry, which she believes is a difficult field. As a mother, she discourages her son from pursuing this career path, wanting to protect him from its hardships. However, she would not forbid him if he were truly determined, noting that she herself remains in the industry despite its challenges. There is no significant character development shown for her, and her notable abilities are limited to her professional function as an in-between animation inspector, ensuring the quality of animated frames between key poses.
