Tuxedo Kamen (Mask), or humanly known as Mamoru (Darien) Chiba, was born on August 3, 1974. He likes to read books, eat chocolate and his favorite color is black with a blood type A. He doesn't have much down points, but he hopes to become a doctor when he's a little older.
He was originally known as Prince Endymion (Darien), where in the English dubbing, it didn't make any sense of it. He represents the planet Earth and was sworn to protect the moon from any danger with the power of the red rose. It makes sense to why he and Sailor Moon are a true couple.
