Black Princess

Britannina's prince and princess were exiled to Japan as their punishment in questioning their father's actions. They lived in Japan and experienced a life different from their lives in the castle. Lelouch, the 11th prince, wore the mask of justice. He became, Zero, the hero of justice, and formed a military group against Britannia. His little sister, Nunnally, was held hostage as he fought. After a year, Nunnally came back, but not as Lelouch's little sister, but as the new Governess of Area 11. Lelouch had no choice but to fight his sister in order to win the war. When the capital was destroyed, Lelouch thought his sister died in the explosion. He took over Britannia and became the new emperor. He became the most evil emperor ever lived. Without his knowing, Nunnally is still alive. He started a war against the whole world with Nunnally leading them. Even though he loves his sister a lot, he didn't have any choice but to fight her. Lelouch won the war and was about to kill his own sister. A masked knight appeared and stabbed Lelouch to death. The evil emperor is now dead and Nunnally as the new empress leads her empire. I am really interested in an anime but it didn't have a good ending. This story is a continuation I made up for that anime series I watched before.The characters' names and some events aren't my idea.
