Compa is a nurse-in-training in Planeptune. While she can be a little clumsy, her bedside manner is soothing and well-rehearsed. Her name is a reference to the company Compile Heart, producer of the Hyperdimension Neptunia games. Due to the Neptunia series being a game that revolves around different universes and dimensions, there are multiple Compas throughout the series, some of them with varying personalities.
