She wiped her face and started to trace the whole place with her chakra sensing technique, as she had done it more than a hundred times.
From a corner of the lab, she discovered a pair of pants and a robe to cover her body while killing those who were observing the updates of the 'subject' in here, and she did some hand signs while concealing her own chakra, revealing a special storage seal pattern on her body.
From the very moment she entered Danzo's headquarters, her motto is to take down Danzo's root division, as she came prepared even though she was captured in this place as a lab rat for two years.
Her aim now is to take everything he took from her clan be whether it sharingan or jutsus, and take anything valuable to Danzo so it will cause him to suffer a huge loss, still within her aim in case she couldn't take the whole root division down in one go.
She remembered what happened before she got captured, the moment she saw Itachi for the last time.
"Sister Itsuho, what are you trying to do by giving this to me?" Itachi looked at the vial of blood she gave him with unease and suspicion.
"I was on a secret mission ordered by Lord Third. It is to investigate Danzo. I was able to discover much evidence against him, but still not enough" She gave him a scroll.
"This scroll has part of it. Once you use this, you will get the other part," she smiled with a hint of mischief, though it didn't reach her present dull eyes anymore.
After Shisui's death, part of her died with him, as instead of caring for her humanity, she decided to ignore everything else so she could achieve what her brother wanted, while her own Sharingan kept influencing her dark thoughts, although her three younger brothers kept her hold on to light before she fell into complete despair.
"You mean Danzo is not a person of the Konoha?" Itachi asked with widened eyes as Itsuho softly chuckled at the little teen's naive way of thinking.
"No, he is, but at the same time he isn't. He wants to overthrow the Third Hokage and become Hokage. So he is far more troublesome to the village than you think"
She indifferently drops the secrets that were hidden from the public, as it doesn't matter to her anymore.
"I couldn't find any traces of his foundation quarters before, but with Shisui's death, he became more daring, as well as his subordinates. So I am planning infiltrate in to the foundation. So if I disappeared suddenly without leaving messages to you anymore, that is the time for you to carry out your plans for Uchiha."
Itsuho put a hand on his shoulder to make sure to remind him of the burden as well as the responsibility he is carrying alongside her.
"Are you suspecting Danzo has a hand in the Uchiha coup, sister Itsuho?" He asked, but a bit skeptical bout it.
"Yes, I highly suspect that. When the nine tails attack, I went to find Aunt Kushina. Undoubtedly, the one who summoned the Nine-Tails is an Uchiha. But I can confirm that he isn't from the clan. But soon after my brother's death, I sensed his chakra signature near the Naka shrine. He was wearing a tiger-striped mask that covered his whole face"
Her expression became serious as she knew his identity, though she was unable to say it, as she remembered the bright Uchiha who always looked after her and how she looked up to that person, as well as how she treated that person as an older brother when she was still sick and weak.
"You mean Madara Uchiha?" Itachi exclaimed.
"I don't think so." She shook her head. "Given Madara's personality, I highly doubt that he would wear a mask. Many people say he snatched his younger brother's eyes to have more power.
But Madara had a habit of writing what happened to him until he left the clan. Reading what he left, I started to think he isn't the person we portrayed him to be. Never mind that; back to the topic."
She started to remember what happened to the other people who were with the red-haired Uzumaki woman that day, nine years ago.
"He blackmailed them with Naruto so he could get the Nine-Tails from Aunt Kushina. The real problem is the timing of his arrival." She said while leaning against a wall.
"You mean someone gave him the whereabouts of Lady Kushina?" Itachi asked.
"Yes, I highly suspect Danzo had a hand in it. But I am not so sure. So wait till my comeback. If I wasn't able to return, you will carry out the plan we made before. And let Orochimaru have that vial of blood." Itsuho gently nodded as she decided something.
Seeing his dumbfounded look, she chuckled lightly. "Yes, I am planning to take down at least a part of the foundation. So that way we can take it down completely after my death. In case war ignites because of our actions, I will have to make sure to stop it too"
Itachi felt confused about what she was saying but decided to trust her as he placed the vial of blood in one of his safe pockets.
"Sister Itsuho..." Itachi tugged at the sleeve of her high-collared Uchiha shirt. "Don't worry, Itachi. You know you are acting like little Sasuke." She smiled at him. "This is the time I have been waiting for. And this might be my last gift to the village and clan." Itsuho muttered the last part as she walked towards the Naka shrine without looking back.

She put all the important sealed documents she could trace in the lab into her storage seal while reminiscing.
She didn't forget about the containers of eyes, including her own, before leaving the lab.
Itsuho put at least a few hundred fire seals on the walls of the lab before leaving the room, clearly intended to activate them later.
Then she used Body Flicker to speed up and cut down the root ninjas she faced on the way to her destination with scalpels she picked up from the lab.
She swiftly made her way towards the library. According to the intel she got during her stay here, Danzo have a copy of a forbidden scroll as well as numerous techniques from clans he hoarded so he can use them to create his own mindless shinobi unit that is rival enough to exterminate a clan.
'This is my payback for what you did to my clan, Danzo. You will never see the precious collection that helped you to create such a private army ever again' Itsuho's shadow clones swept all the things she could sense into her storage seal.
Sensing ninjas were coming to the library, she smirked as she kept unlocking secret seals in the walls and reversing curse seals in there to her advantage.
Many scrolls appeared before her as she put all of them into one scroll before putting it into her storage seal in a swift motion.
While doing that, she kept putting another set of fire imprint seals on the wall so she would be able to blow up everything later.
Soon, she moved towards the door as she sensed more than twenty ninjas around her with various tanto and katana and many short and sharp swords, while she wielded the scalpel she found from the lab that she was imprisoned in, as she didn't have a chance to go to the armory.
She didn't feel scared; instead, relief appeared on her pale face as she wanted them to hunt her down. That way, she would be able to take down more of those shinobi.
Sensing the new changes in her body, she started to weave hand signs.
"Wood Style, tree blind eternal burial"
Huge trees trapped most of the ninjas in a large tree as she used another technique.
"Wood Style, cutting jutsu"
Soon, she started to impale her enemies with wood sticks that started to grow on them, killing almost everyone in fast motion; she flickered away.
