Tuxedo Mask, Darien Chiba, Prince Endymion, & King Endymion
is what you would call a simi-genius. He excells at anything he puts his
mind to. But with this intelligence comes the mysterious air that follows.
He's unknown to many and dubbed as too cool and up-tight to be around. He
knows that and in a way flunts it, especially to Serena at the beginning
of the Manga.
When Darien first enters the picture he immediately insults our beloved heroine. He doesn't care to look further into her life because he's on a mission, to find the Silver Imperium Crystal. But once Serena's love and their past together sink in to him, he is more kind and generous than ever. In a way, Darien is afraid to love. The only people that he loved died and he hasn't cared about anyone since. Serena is the only one that can break down that rough barrier and exspose the Darien that we all know and love.
Darien lived in a flat in the CrossRoads Plaza alone. He tends to like being alone. He left the orphanage as soon as he could manage live on his own. Because he has had to work all of his life, his character has had exstencive building. He likes studying and going to school, he is even accepted to Harvard here in America at the beginning of the StarS series. All is ruined when Galaxia takes his Sailor Crystal, but at the end of the StarS series, Serena resurects all of the Senshi and Darien.
