Is kurai a moon princess

Kurai, also known as Sailor Moon ("Dark" in her Sailor name was taken out; she was previously called "Sailor Moon Dark"), is a fan-made character created for the as-yet-unaired "sixth season" of Sailor Moon, Sailor Moon: Sacrifice, created by xKaosu. She is essentially Princess Serenity's long-lost (apparently fraternal) twin sister who wields the same power as Usagi.

The fan-made videos and artwork featuring Kurai are generally re-colors of Sailor Moon, with Kurai having black hair instead of blonde, black on her costume instead of white, blue, or yellow, and dark eyes instead of blue ones.
