Kuriyo Andō is a classmate and close friend of Hibiki Tachibana and Miku Kohinata at Lydian Music Academy, distinguished by her short beige hair with a longer left-sided strand and vivid pinkish-red eyes. Often clad in her school uniform, she navigates social dynamics with playful humor, dubbing Hibiki "Bikki" and Miku "Hina" to foster camaraderie within their group. Her perceptive nature surfaces during conflicts, such as urging Miku to reconcile with Hibiki amid their strained interactions.

Her lineage centers on Tronbokril, a family relic entrusted to her by her grandmother after her mother relinquished guardianship due to personal turmoil. The artifact’s generational legacy passed to Kuriyo following her mother’s departure, subtly shaping her formative years without explicit elaboration.

During *Symphogear GX*’s events, Kuriyo briefly harnesses Hibiki’s Gungnir relic in Episode 3, channeling its power through song to repel an Alca-Noise assault. This act earns her a place in S.O.N.G. as a Symphogear wielder. The relic adapts to her signature hue as "Blue Gungnir," materializing a two-handed lance and unleashing energy strikes like "DISTINCTIONδTHRUST." She later masters Tronbokril, executing whirlwind techniques such as "BOREALδVORTEX" through precise energy manipulation.

Kuriyo contributes to team strategies, syncing her attacks with allies’ Superb Songs for amplified assaults. Though her prominence wanes in subsequent seasons, she reappears in *Symphogear XV* alongside companions Yumi and Shiori, reaffirming their trio’s bond. Alternate timelines, like the *Mechvaranus* storyline in *Symphogear XD Unlimited*, cast her as a wielder of the eponymous relic.

A fleeting animation discrepancy in *Symphogear G* Episode 11 erroneously depicted her hair as black, rectified in later Blu-ray editions—a minor note underscoring her consistent visual identity across adaptations.
