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 and kissed her. After waking up in Nemesis she tried (after Demande kissed her) 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 the future Black Lady to destroy the space-time continuum. His plan was stopped by Sailor Pluto. As he attempted to kill Sailor Moon, she and Tuxedo Mask destroyed him using the Cutie Moon Rod.


Demande can shoot attacks from his third eye, which remains hidden under the Black Moon symbol on his forehead, until he uses it to attack.


  • 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".
  • His estimated age is confirmed "18" exactly in the Sailor Moon "Materials Collection" by Naoko Takeuchi.
