Phantom Thief Noir A legendary phantom thief who appears all over the country, successfully pulling off heists every time. This is Rena's secret identity. She has committed numerous thefts. Because her targets are always works of art and she sends a calling card before the theft, she is called a phantom thief, a title she has accepted and now uses to refer to herself as "Phantom Thief Noir." She has long black hair and wears a pure white suit and cape, with a domino mask covering her eyes. Phantom Thief Noir does not steal for money alone; she prefers to steal "artworks that are not where they belong." This includes cultural properties that have been unjustly privatized, artworks about to be sold on the black market, and pieces whose true value is not understood. She steals these items away. At first glance, she might seem like a chivalrous thief, but since she keeps the stolen art herself, claiming she will "manage them until someone who truly understands their value appears," calling her a hero is a bit questionable. Her creed is to "turn the act of stealing itself into art." She sends a crime notice. She always specifies the time. And she appears exactly where the police have set up heavy security. However, she never touches anything other than the target item. She does not harm security guards more than necessary. She does not destroy buildings. She does not cause meaningless chaos. In the end, she always leaves behind a single white card.
