The Uchiha who were stubborn at the beginning were slowly swayed over a period of months. This was the same clan who rejected Madara and his quest for power. They had fought for so long and had just wanted peace. A lot had changed within the clan, but that had not. Which was why despite their anger for years of discrimination, they accepted the good-will with open arms.
There was an effect of the almost kidnapping that she hadn't counted on-Massive sympathy was directed towards their two clans, and almost all of Konoha, The other clans and village elders, united behind them, putting on a united front for the Kumo nin. She had just wanted to get her and Hinata's clans on better terms, no way had she thought this would happen. But she was glad all the same.
Fugaku and Hisahi had been brutal in their demands, but her father thought smart. Instead of demanding all out war, he wanted an humiliating apology, and they edited the treaty at the last minute-putting Kumo at a disadvantage. But they couldn't back out of it now, because their military might have been stronger but they were being held hostage. They would go back with their tail between their legs, locked in.
There was also another unintended side effect. Itachi would hardly let her out of his sight. He would come home from training and his eyes would dart to her. He actually 'trained', with them, making sure she knew basic self defense. He rushed home from school and refused to start his homework unless he saw her first. It's like he forgot that she was different than Sasuke.
She must have given him quite a scare.
And when her safety was assured, he threw himself into training and she knew just by looking at him that he was already able to graduate. She stretched out her senses, carefully searching for him, and recoiled in slight shock when she sensed two of him. One throwing kunai in the yard, the other watching her from the roof. A shadow clone then.
This threw a huge monkey wrench in her plans.
How could she carry out her plots and scheme while maintaining the guise of an innocent 3 year old when Itachi the prodigy always had eyes on her?!
At any rate, Sasuke was playing over at Choji's house, and Mikoto was getting ready to make her rounds within the clan. Even then, with Mikoto as an accomplished Jounin, Itachi would still sometimes send a shadow clone.
But thankfully he didn't this time.
They went and visited relatives, some who had been effected by the Nine-tails attack and then an idea hit her. She tugged Mikoto's shirt and whispered into her ear if they could set up a donation fund for those effected by the attack.
She didn't know why she hadn't thought about it earlier and vowed to find out more information. Mikoto had seen the potential that idea nugget had, and had booked it to the Uchiha art institute, which was a thing now. They had already been the most powerful clan, and had even lucked out and avoided the nine-tails in the attack. So donating a certain amount every month wouldn't harm them. It fact, it would improve relations. Maybe they could even donate time to help repair some of the areas that are still damaged!
People were suspicious on how they avoided damage-this could clear the air so to speak. She had learned that some Uchiha had helped with evacuation and afterwards with cleanup. But not rebuilding.
It had taken two weeks to get everything in line, and even then they started out small, with about 5% of the artists earnings plus the other 10% going to charity.
Konoha was at first in shock, and rumbles and rumors spread.
But after the funds put clothes on orphans backs, and some members were spotted helping with rebuilding, thanks you's were sent in, and there was an uptick in the artists sales. Some people though were defiantly offended by their offer of help, dead set in their belief that the Uchiha were the ones who caused it.
But seeing a little Naruto run away in the distance with a radiant smile on his face was entirely worth it.
In canon, the nine-tails attack was the beginning of the end.
Maybe here it could be the start of something new.
