Goltschmidt Tachibana, Rina

リナ・ゴルトシュミット・タチバナ

Rio's childhood friend, recruited by Tom Howard to work as a dealer. During her childhood, her mother was hospitalized and her father was frequently away on business trips, so she was raised by Risa and Rio, with whom she shared a sibling-like bond. She possesses a mysterious energy that leaves her customers weary, in contrast to Rio's aura, which energizes them. It is later revealed that she is Rio's half-sister and a Gate Holder working under Cartia, who is revealed to be her aunt. She seeks revenge on Rio and her mother, Risa Rollins, who allegedly eloped with her father, causing Rina's mother to fall into a coma. She is also a Roll Ruler, with abilities that far surpass Rio's, and holds five Gates; four of these were given to Linda, Jack, Queen, and King, while the fifth is the Ace Gate.
