Oichi AU

Younger Sister of The Devil King of the Sixth Heaven, and first of the Unification Trio, Nobunaga Oda, Lady Oichi Oda, was born to be a pawn for her brother.
She did not care. The Man, Brilliant as he was, Was mistreated, ignored, and insulted for his actions to everything and everyone. He was a Fool, The Fool Of Owari.
Oichi, stood by him, helping him as needed. Even when he had sent her to the Azai clan, to wed Nagamasa Azai, the clan head. She still protected him.
She could not have a child though. No mater how much her husband and she tried, they had no child. Nagamasa never let that stop his love of her and nor did she. Months after they were married, Nagamasa came down with his family Disease. He weakened quickly, his hair turned white and he could barely stand for more then an hour at a time. Oichi was there, supporting and helping him through it. A trait that Nagamasa never gave up, and to this day, Oichi never understood how, Nagamasa would pull out Wisteria and place it in her hair when she was sad or upset.
Then, Azai and Asakura were betrayed by Nobunaga. Oichi, stood by her husband, waiting for him well until his sickness had bested him. During the siege of Odani Castle, Azai had passed. None knew of this, and all new his time was soon, moral was low. Then, Dressed in his armor, Roaring into battle, Oichi lead a desperate charge against her brother. The Battle was long. The Azai Forces had a burst of moral the never seen or felt before, their lord, charging into combat in such a way inspired them to keep fighting.
Oichi lead. She slew many a soldier as she forced her way to her brother. Besting even the likes of Tadakatsu Honda, the mightiest Warrior of their period.
Nobunaga fought his sister, unaware, or immune to her pointless struggle. None at the time knew. None to this day know.
During their Duel, Nobunaga knocked off Oichi's helmet and went for the killing blow. Nagamasa's ghost caught the blade, saving his wife. The pair kissed one last time before he left, telling Nobunaga he would wait at the gates of hell.
Nobunaga simply laughed. The Azai, we defeated and exterminated. Aside from the child that Oichi held with in.
Oichi never recovered from his death. But the child that she mothered, helped keep her going and once more she found herself a simple Pawn of her brother's.
He never used her again. Gifting her to Katsuie Shibata with her child. He was old, a strong warrior, and wealthy from his loyalty and deeds.
Oichi was resentful for such a life forced upon her. But, she grew to understand why as time went on. Katsuie never sought out to sedate physical needs.
He had fed himself well though his years. The woman who used to frequent their home at first, made it clear, he sought only a family, a wife to love, and a child to raise.
More time passed, Oichi came to love him, as she did Nagamasa. It hurt at first. She spoke with Katsuie about it, who told her that they would go to Nagama's grave for her to talk with him.
The trip was long and only a day was spent at the grave. A night to be exact. Oichi had spent the night at the grave talking with Nagamasa's ghost. It was as if the man, who had died years ago, knew his love would need his blessing and appeared on this one day to ensure, she got it.
The pair lived quietly with Katsuie leaving for war constantly. That was, until Nobunaga passed. A fight over Nobunaga's successor arouse. More Civil war was unleashed and Katsuie found himself fighting more then he had been when marching under Nobunaga.
It was a losing war though. The grizzly veteran was unable to keep the more reckless from attacking while snow had him locked with in his fife.
He and Oichi both went to fight at Shizugatake and were bested. They retreated to the castle and fought over what they should do. Oichi could not handle losing another husband. The Warrior told her to leave with their daughter, flea to the Date. The child would arrive safely, but the gold she was left with, stolen by her deliver.
Oichi and Katsuie both commited suicide after Katsuie set fire to the castle of Kitanoshō.
