The Akatsuki is known as the Red Dawn.
The Akatsuki is mostly all males but with one female aka Konan.
Black Dusk is mostly all females but only one male aka Haku.
This my version of my Black Dusk: (If we only were doing in Naruto world.)
I would pair:
1. Fuka and Fuen.
2. Guren and Haku.
3. Konan and Kurenai
4. Mei and Hana.
5. Tsunade would be the leader of the group.
