Анджеліка Бернс

A private investigator from the Federation Bureau, Angelica is well aware of the government's corruption by the Criminal Guild. She has been chasing Mister for the past four years and has been fascinated with him since her early days as a traffic cop. Angelica is a notorious glutton with an apparently superhuman metabolic rate, although she may just be hypoglycemic. [Wikipedia] Though her fixation on Mister appears to be for romantic reasons, she claims that isn't the case. Even though her goal is to catch Mister, she'll always prioritize saving him from the 12 sisters first, in order to catch him herself.

After tracking down Mister on planet Graceland and hearing his motivations for being there, she decides to help him out by attempting to stop the federation's plan to destroy Graceland.
