Description
Keith Harcourt is a seventeen-year-old aristocrat who leads a double life as the legendary phantom thief known as the Black Rose. He is the older twin brother of Francis Harcourt, though he is only slightly older, and the two share a strong physical resemblance that often leads to confusion. While both brothers come from a privileged background, Keith has rejected the constraints of his social standing, choosing instead to operate outside the law to address the injustices he sees in the world.

As the Black Rose, Keith is a mysterious and dashing figure who steals from wealthy aristocrats and distributes his gains to the poor. He believes that many rich people are frivolous and self-centered, and he views traditional noblesse oblige as insufficient for solving the deep inequalities in society. His criminal exploits are characterized by a sense of showmanship: he is known for wearing a black costume with a cape and mask, leaving calling cards to announce his intentions, and placing a black rose at the scenes of his thefts as his signature. These actions have made him famous among the public and journalists, who hold a certain admiration for his Robin Hood-like mission.

The motivation for Keith's vigilantism stems from a deeply personal place, particularly the death of his mother. While his more innocent brother, Francis, only saw their mother's kind and gentle side, Keith perceived her secret unhappiness as a woman trapped in a gilded cage, confined by the expectations of aristocracy. This realization left him disillusioned with noble life and fueled his cynical view that merely being born into wealth and feeling a sense of duty toward the poor is not enough to create meaningful change. He walked away from his family at the age of fifteen after finishing his schooling, choosing instead to live by his own code.

In terms of personality, Keith is often described as cold, quiet, and distant. He harbors a certain self-loathing for being an aristocrat himself, which contributes to his reserved demeanor. Unlike his brother Francis, who is more openly gentle and idealistic, Keith is far more cynical and disenchanted with the world. He feels things very strongly but keeps his emotions hidden beneath a calm exterior.

Keith's role in the story is intrinsically linked to the protagonist, Nadja. He crosses paths with her multiple times during her travels with the Dandelion Troupe, and their initial encounters are marked by her frustration with his dry wit and his methods. However, as she comes to understand his true motives, she begins to empathize with him. A crucial revelation is that Keith is the real Knight of the Bright Eyes, the person who rescued Nadja from a fire at the Applefield orphanage when she was younger, a heroic act that forms a deep, unspoken bond between them.

His feelings for Nadja are a central part of his character arc. He falls in love with her, and her fierce love of freedom touches him profoundly, leading him to appoint himself as her protector. This creates a complicated love triangle with his brother Francis, as both twins are in love with the same girl. Keith often suffers silently, believing that his love is not returned because Nadja appears to be more deeply in love with Francis. He has demonstrated his devotion through significant acts, such as retrieving a precious brooch for her, a mission that resulted in him being captured and tortured by Hermann, the story's antagonist. At another point, he successfully saved Nadja when the Duke attempted to send her away to a boarding school. He also uncovered the secret of Nadja's true heritage as a member of the wealthy Preminger family, a discovery that made him wary of her entering a world of aristocracy that he believes brings only unhappiness.

Keith Harcourt does not possess any supernatural powers; his notable abilities are those of a master thief and a skilled individual. He is athletic, stealthy, and highly intelligent, capable of planning elaborate heists and evading capture. His trademark methods, including his calling cards and black roses, speak to a careful and theatrical mind. His greatest strengths, however, are his unwavering sense of justice, his willingness to sacrifice his own comfort for the sake of others, and his deep capacity for love and protection, even if he expresses it in a reserved and painful manner.
