Wakaba Satsukimidori serves on the Prima Angels team as Prima Spring Green. Her transformed state presents a fairy-like appearance marked by functional wings and puffy cuffs at her wrists and ankles, complemented by light green hair and bright pink eyes.

Assessments characterize her as fundamentally timid and kind-hearted, with a notably shy disposition. She exhibits difficulty interacting with machines or technology. A consistent Tohoku dialect colors her speech during dialogue.

In combat operations against antagonistic forces, she wields a whip as her designated weapon.

Information regarding her civilian background, recruitment process, character development trajectory, or specific narrative contributions across seasons, films, or ancillary media within official sources remains unestablished.
