Fifty years had come and gone since the legends of the lost in time Samurai had begun.
He did not age. Time had no effect on him.
All of the time portals were destroyed. His sword had left him. It seemed that Aku had won.
His mind was coming undone; his own inner self telling him that there was only one honorable way left.
And then, he met her.
The Daughter of Darkness. The only good thing that ever came from Aku.
She had once cursed his name as a blight on Aku's world and tried to kill him, but when she learned that she had been deceived, she vowed to help the Samurai stop Aku.
She stopped him from committing seppuku.
She stopped an Army from destroying him.
She had even stopped her own mother. That horrible woman who had twisted her fate and doomed her sisters.
She had helped him regain his sword and he began to trust her with his life.
Eventually, they discovered that they felt more for each other than either of them had ever believed possible.
Within a short time, Aku discovered the existence of his Daughter, and used her against the man she loved, twisting her into a demon and controlling her.
It was only by reaching out to her heart that the Samurai was able to free her.
In a sudden discovery, the Daughter realized that she had all of her father's powers.
All of them.
Before they allowed Aku any other action, the Daughter tore open a portal in time and guided the Samurai back to his original time. The time before Aku enslaved the Earth.
In was in that lost time that the Samurai struck down Aku, and his presence vanished from the world.
Unfortunately, being that the Samurai was from a time long before her birth, Aku's death also brought about her own undoing, and the Daughter of Darkness vanished in his arms.
The Samurai wandered in despair. It was only upon seeing a ladybug, a creature that had been involved in the first moment of peace between the two of them, that he began to feel a sense of peace, for he believed that the Daughter's soul was now free of the bonds it had held with Aku.
