Operator 21O

Serving as a vital link between headquarters and frontline forces, this YoRHa O-Type model functions as a dedicated messenger delivering essential combat instructions. Tasked specifically with providing technical and operational support to 9S, she maintains a professional demeanor characterized by a composed and disciplined temperament. While her personality is notably more rigorous and serious than the more lighthearted 6O, her steady presence remains crucial for the success of active soldiers during their missions.
