Darien grew up in an orphanage because when he was little he was in a really bad car crash that killed his parents. He doesn't remember the car crash, he actually lost all of his memory even his real name…he was given his name (Darien) in the hospital.

Tuxedo Mask fights with red roses which he throws at the enemy, his cane, Tuxedo La Smoking Bomber, and Pink Sugar Tuxedo Attack (with Sailor Chibi Moon…and this wont happen ever on our site). The rose is red when he's Tuxedo Mask, white when he is moonlight night, and black when he is Prince Darien.

In the time of the moon kingdom Darien was Prince Darien and Prince of the earth. He was engaged to Serena, princess of the moon kingdom. After the evil Queen Beryl attacked the moon, Queen Serenity sent all of the royal court into the future to be born again as humans.

When the Negaverse, ruled by Queen beryl< started attacking the earth the sailor scouts were found one by one in order to fight to save the earth. Darien was transformed into Tuxedo Mask anytime the scouts were in danger. At first he had no memory of this happening but it eventually came to him.
