Rinko Jerrard comes from a rich family and in the past many people had pretended to be her friend so that she would buy them things. Disillusioned with the seeming coldheartedness of the world, she succumbs to Robert's hypnotic charisma and joins the Ten. Initially, Rinko has a crush on Robert since he treats her as a real friend but she eventually sees Robert for what he really is and joins up with Ueki, indeed becoming his guardian and constant caretaker. Rinko's Celestial King Candidate is a man named Nikay, one of Margarette's followers whom she hasn't seen since the battle began. She loves all animals, taking an immediate liking to Tenko, but her weakness for cute things makes her vulnerable to Ban's power. Note that it is wise not to insult her no matter what, for she has a side to her that makes her incredibly unhealthy for the person who insults her. She doesn't seem to realise that she has this "evil" side and fortunately for her, she forgets whatever her "evil" side says or does. This "evil" side seems to be activated whenever someone insults her.
