   Darien (Mamoru) lost his parents at a young age that is never specified. He has been living alone since he was old enough to move out of the orphanage. He once lost him memory when he became Queen Beryl's slave, and his spirit became the Moonlight Knight (Tsukikage no Knight). 
Darien is destined to be with Sailor moon forever, dispite any obsticles. He first appears in episode one, when Sailor moon trows her crumpled up test paper at him. Darien replies,"30, admirable, are you stupid or just incredible lazy." When he later saves Sailor moon, she becomes obsessd with him.

    Later on in the season Mars suggests he may indeed be Tuxedo Mask, but nobody buys it. Still, Mars goes out with Darien a few times. It isn't really until Sailor moon is revealed as the moon princess that this has to come to an end. I was happy about this, because I'm a mars and chad fan.

     In season two, Darien soul is revealed as the moonlight night, sent to help and protect sailor moon. Okay, get this, Sailor moon is sad when Dariens soul re-unites with his body. It was like she somehow liked the moonlight night more than Darien.

      In the Rini Chronicles, Darien get's these bad dreams, that tell him if he marrys Serena, something terrible will happen. So, Darien breaks up with her. Serena is HEART BROKEN. At one point in time, she almost couldn't go on.
