Ueda acts as the vital liaison bridging communications between the divine creator and the animal design department, managing project requests and approvals. She holds a supervisory position over Shimoda and oversees teams like the insect design unit, delivering God's final decisions on animal design submissions.

Her appearance features fair skin, long wavy blond hair, and blue eyes. She wears a distinctive black ensemble: a short skirt paired with a low-neck suit coat. Functional angel wings are integrated into the back of her blazer, mirroring Shimoda's attire.

Ueda exhibits a consistently cheerful personality, always willing to assist colleagues with their projects. She displays notable physical strength inherent to her angelic nature, demonstrated on multiple occasions—such as effortlessly capturing a large escaped prehistoric dragonfly prototype, an act she dismisses casually.

Within the heavenly organization, Ueda maintains collaborative working relationships with fellow angels. She coordinates daily operations with Shimoda and engages in cross-departmental activities. This includes interactions with Yokota, a representative from Hell, concerning collaborative ventures like theme park creature designs. Her name, signifying "upper rice paddy" or "above," reflects her senior position relative to Shimoda ("lower rice paddy") in the celestial hierarchy.
