The Black Dragon

(The world is populated by demons. There is technology, but think of it as run by magic and such.)

Life wasn't simple of Lelouch. His mother died protecting her children, when he was the tender age of ten. Her sacrifice was in vain, when her offspring Lelouch and twins Nunnally and Rolo were kidnapped. At some point, Lelouch's will was so strong to survive and protect his siblings that he attracted a succubus witch. She freed and took them in.

They moved to Japan, and for years they believed they found peace. Lelouch found love, and they mated at 17. Then Britannia attacked, the pair got separated. Japan fell, and became Area 11. Unable to flee Area 11, the group found solace in a safe zone community. There, Lelouch continues to care and provide for his siblings and his twin boys.

Six years later, the peace they foolishly believed would last was broken when the royal family discovered them. It is then he learned of a prophecy. When a Black Dragon Lord and White Dragon Lord unite, their unison brought peace in a war torn world. The catch?

Lelouch was the Black Dragon Lord.
Schneizel was the White Dragon Lord.

Now he must choose between his old flame or consider it lost to his sister, and accept the prophecy. Lelouch puts the safety of his children and siblings above everything else, so whichever actually keeps their promises will win.
