ONA
Description
Prince Demande, also known as Diamond, is the charismatic and ruthless leader of the Black Moon Clan and the primary antagonist of the second season of Pretty Guardian Sailor Moon Crystal. He is a young man with striking silver-white hair and piercing purple eyes, typically dressed in an ornate white uniform with a high collar and a long cape. His name and the large diamond pendant he wears reflect his aristocratic and gemstone-themed persona.
Originally, Demande and his younger brother Sapphire were inhabitants of Crystal Tokyo in the 30th century who grew disillusioned with the peaceful, prolonged rule of Neo Queen Serenity. They viewed the queen’s advanced, utopian society as stagnant and unnatural. After being banished to the dark, desolate planet Nemesis for their rebellion, they came under the influence of the malevolent Wiseman. Demande was granted the power of the Malefic Black Crystal in exchange for following Wiseman's guidance, becoming the figurehead of the Black Moon Clan's crusade to conquer Crystal Tokyo and alter history itself.
Demande’s personality is defined by a potent combination of arrogance, cruelty, and obsessive desire. He is presented as a villain who believes in the supremacy of power and the right of the strong to dominate. His initial political objections to Crystal Tokyo are gradually consumed by a much more personal and possessive fixation. After glimpsing the future Neo Queen Serenity in her frozen crystal prison, he becomes obsessed with her, a fascination that later transfers to her past self, Sailor Moon. In Sailor Moon Crystal, this obsession takes on a deeply unsettling and aggressive quality. He abducts Usagi Tsukino, the civilian identity of Sailor Moon, and attempts to force her to submit to him, displaying a chilling disregard for her will or safety in his desire to make her his queen. He is also shown to be utterly ruthless, having no hesitation in harming others to achieve his goals.
Within the story, Demande serves as the orchestrator of the Black Moon Clan's invasion of 20th-century Tokyo. He commands his subordinates, including Rubeus and Esmeraude, to collect energy and hunt the young Chibiusa, all while he remains in the future, plotting. His primary motivation is twofold: to destroy the legacy of the White Moon and to claim Neo Queen Serenity or her past incarnation for himself. His role becomes more direct when the Sailor Guardians travel to the 30th century, where he personally confronts them.
Key relationships heavily influence his path. His bond with his younger brother Sapphire is his most significant personal connection. While Demande often dismisses Sapphire’s caution and wisdom, his brother’s death at the hands of Wiseman is the catalyst that finally shatters his illusions of control. He also clashes with Esmeraude, who is romantically obsessed with him, though he remains indifferent to her affections. His most crucial relationship is with Wiseman, his seemingly wise advisor who is, in reality, a dark entity manipulating the prince. Demande believes he is using Wiseman's power for his own conquest, but it is gradually revealed that he is a puppet serving a much larger and more destructive plan.
Demande undergoes a significant but tragic development. He begins as a confident, commanding leader fully in charge of his crusade against Crystal Tokyo. As his plans fail and he descends further into his obsession with Sailor Moon, he becomes reckless. The death of his brother Sapphire is a pivotal turning point, forcing him to realize that Wiseman has been deceiving him all along. This revelation transforms him from a deliberate conqueror into a vengeful and desperate figure. In the final confrontation, he turns against Wiseman. His development reaches its end not in conquest, but in a moment of sacrifice; he throws himself in front of an attack meant for Sailor Moon, redeeming his villainy as he dies in her arms.
In terms of abilities, Demande is a formidable antagonist. He wields the power of the Malefic Black Crystal, which allows him to fire powerful energy blasts and beams of destructive force. His signature ability is known as the Evil Eye or Demon Eye, a power granted by Wiseman that manifests as a third eye on his forehead. This eye allows him to hypnotize his victims, paralyze them, or exert telekinetic control over them. He is also capable of levitation and teleportation. Despite these formidable powers, his psychological vulnerabilities and over-reliance on the unstable power of the Black Crystal ultimately lead to his downfall.
