J is very loyal to the JCJenson company to the point of total (and almost unhealthy) fanaticism.

She has an arrogant, serious and professional personality most of the time although she also likes to tease others. 

J is the leader of the Murder drone squad made up of her, V and N.
Her squad's goal is to kill all the worker drones on the exoplanet Copper 9. She also needs to drink the oil from the worker drones so she doesn't overheat. She really enjoys killing worker drones and brags about them
