Description
Yumi Itaba is a classmate and friend of Hibiki Tachibana and Miku Kohinata at Lydian Music Academy. She possesses green eyes and medium-length brown hair, typically styled in two pigtails secured with pink ribbons, and stands 154 cm tall, featuring distinctive cheek curls. Her standard attire is the Lydian Music Academy uniform, completed with knee-high socks and a tie.

Energetic and genki by nature, Yumi harbors a strong passion for anime, frequently drawing parallels between real-life events and anime tropes. This habit leads her to exclaim catchphrases like "This isn't an anime!" during overly dramatic situations. She occasionally breaks the fourth wall, offering meta-commentary on narrative conventions. While generally upbeat, extreme stress can trigger hysterical reactions. Yumi also exhibits shipping tendencies, particularly concerning Hibiki and Miku's relationship, and expresses frustration over Hibiki's occasional denseness.

A significant moment occurs in the first season finale when Yumi, utilizing her small stature, crawls through a maintenance tunnel to access Lydian Academy's backup generators. This action enables crucial communication to Hibiki and aids the survivors' coordination, which Yumi explicitly references as her "spotlight moment." In later seasons, she participates in school activities such as a karaoke contest, cosplaying as the titular character from *Denkō Keiji Ban* and recruiting friends for a performance that fails to advance.

Yumi consistently appears alongside Kuriyo Andou and Shiori Terashima, forming a trio. Their roles lessen in later seasons, culminating in only a brief, non-speaking appearance in the first episode of the final season. However, within the mobile game *Senki Zesshō Symphogear XD Unlimited*, Yumi and her friends receive expanded focus in the "Mechvaranus" alternate universe storyline, becoming central characters wielding the eponymous weapons.

Throughout the series, Yumi remains a supporting figure whose anime-centric perspective and occasional decisive actions provide both levity and minor plot contributions.
