Prince Demande is the leader of the Black Moon Clan. This is the original depiction of the character created by Naoko Takeuchi. He is Sapphire's older brother.




Black Moon Arc

Prince Demande resented Crystal Tokyo, believing them to be corrupt and that their lifespans were profane. Wiseman approached him and convinced him to use the power of the Evil Black Crystal, Demande planned to use the power of the crystal to time travel and create a new history before the reign of the Moon Kingdom. When the Black Moon Clan attacked Crystal Tokyo the first time Neo-Queen Serenity went to find her daughter, Chibiusa. Prince Demande then became obsessed with the Queen and kidnapped Sailor Moon, whom he realized was the same person. After waking up in Nemesis she tried to transform but came to realize the dark energy of the planet had absorbed her powers. However she managed to escape with her friends and caused the palace to collapse. After losing Sailor Moon, Prince Demande realizes he was simply being used by Wiseman and revolted against him. In the process Demande was forced to kill his brother and used the Silver Crystal he got from Sailor Moon and another from from the future Black Lady to destroy the space-time continuum. His plan was stopped by Sailor Pluto. After this he attempted to kill Sailor Moon, but was killed instead by Sailor Moon and Tuxedo Mask.


Demande can shoot energy waves from his hands, and also hypnotize others using the third eye on his head, which rarely opens.


  • The spelling of his name is inconsistent. It is sometimes spelled as "Prince Diamond", "Prince Demand", "Prince Demond", "Prince Diamand", "Prince Demando", "Prince Diamonde" and "Prince Daimande". The English rerelease manga spells his name as "Prince Demande".
  • He is showed to be obsessed with Neo-Queen Serenity and even kissing Usagi on the lips, implying that he is in love with her.
