This infiltration cyborg possesses a unique Deep Diver ability, allowing her to swim through solid objects like rock, and a cybernetic Periscope Eye on her finger that bypasses electronic and magical security. Despite a cheerful demeanor, she carries an air of suspicion among the group. Her specialized abilities make her a highly sought-after asset for Scaglietti and Uno. Positioned centrally in the Numbers' origin, she often serves as a connecting link between her siblings and shares a good rapport with Wendi due to their similar personalities and shared learning experiences.
