Mulan Rosé

A magician, her real name, age, and career are unknown. She's interested in spirit cases and those involved, and often quietly shows up at the Black Rabbit unexpectedly. She talks like a dandy gentleman and carries a mysterious air around her. It's later revealed that she's a famous magician known for escaping sinking ships or falling airplanes alive.
A certain someone requested her and Ban to do research on spirit cases. She's highly knowledgeable on spirits and the occult in general. A sucker for gems associated with spirit cases, she goes to great lengths to find them. She thinks highly of Kijima's abilities and talents; she frequently stares sharply at him like a panther watching its prey.
