Anko's face was only couple of centimeters from Sasuke's face. Sasuke was a handsome boy, Uchiha genes were no joke. If he was a little older Anko might consider upping her game. Seeing that Sasuke was not going to back down, so she did. This made Sasuke smirked.
ANKO: "I heard you specifically asked to have me as your partner."
SASUKE: "I wanted to study your curse mark."
ANKO: "We already studied this curse mark, do you think you can do better than the department who specializes in fuinjutsu in our village?"
SASUKE: "I don't want to brag but I'm the best in the field of fuinjutsu. No one alive can compete with me in fuinjutsu."
ANKO: "We will see about that. Hokage told me to cooperate with you so I will allow you to study it."
SASUKE: "Don't worry, you won't regret it."
Sasuke spent the next month training, going on few missions with Anko and studying the curse seal with help of Kushina. Anko and Sasuke become friends as they spent a lot of time together, and they also flirt with each other trying to make the other one blush. At the start Anko wasn't happy working with Sasuke, as he was not even thierteen, but she acknowledged his strength as they performed few missions together. She didn't have to lift her finger in a single mission and neither do Sasuke, only thing that happened is, color of Sasuke's eye changes and the enemy would be incapacitated. They haven't faced an enemy who can bypass his genjutsu.
As Sasuke expected, Naruto become perfect jinchuriki in less than a month's time. Jiraya was astonished, Tsunade was also speechless. She wanted to praise Naruto for his effort but Jiraya informed her that Sasuke promised him that he will make Naruto a perfect jinchuriki in a month. She immediately summoned Sasuke to ask how he did it.
TSUNADE: "How did you manage to make Naruto a perfect jinchuriki? Even though my grandma can use a lot of ability of the kyubi, she still wasn't a perfect jinchuriki."
Jiraya was also very interested in his answer.
SASUKE: "I can answer you but you won't like the answer."
TSUNADE: "Just tell me."
SASUKE: "To become a jinchuriki, you need to cooperate with the tailed beast sealed inside of you. For that you need to become their friend, and you can only become their friend if you understand each other.
Everybody misunderstand the tailed beast, they are not mindless monsters, they are intelligent creature. They would have lived their life peacefully and if you approach them with friendly intent, they would even become your friend. But you know the nature of us humans, they thought of tailed beasts as weapon and tried to capture them to use them in their war.
You know that Madara was an as**ole right, he used the genjutsu of MS on Kyubi, and use him to battle your grandpa. Same thing happened the day fourth Hokage died. A crazy as**ole with MS released the kyubi and forced him to attack the village. Tailed beasts would never attack humans unless provoked.
Everybody thinks of your grandpa as a 'Hero' but that son of a bi**h captured every tailed beast and give them as presents to other villages. He was one of the biggest moron in the history of shinobi, I don't know what was wrong with his head that he thought he can achieve peace if he let the other village gain the power of tailed beasts."
Tsunade was angry when Sasuke cursed her grandfather, like Sasuke said she didn't like his answer. Sasuke didn't pay attention to Tsunade's angry face, he continued.
SASUKE: "First of all Tailed beast has nothing to do with human war, and that crazy as**ole shouldn't have captured them. Secondly, even if he captured them, he should kept all the tailed beast in leaf village or at most shared them with Uzushiogakure. They were friends with our village. If he did that, no other village would have dared to start any of the ninja war and your grandma's clan wouldn't have been wiped out. Only reason no ninja war started during his time was because everyone feared him, the moment he died, first great ninja war started. If Konoha controlled all tailed beast, other village wouldn't have started ninja war due to their fear.
Everyone leaf shinobi who died by the hands of tailed beasts of other village, their blood is in his hands. He is the cause of their death.
Anyway, I talked to the kyubi inside Naruto with no ill intentions. Kyubi can detect negative emotions, so he can tell that I was sincere. You know Naruto, he is the best person in the world. I don't know how he remains so positive, if I were him the first thing I would do after gaining the nine tails power would be dropping a bijju bomb right in the middle of the village for what they did to him all those years.
Anyway, I told Naruto to befriend the Kyubi, and Kyubi couldn't resist Naruto's positivity, he let go of his resentment and hatred he is holding for centuries and become friends with Naruto."
Tsunade didn't say anything, she was angry and she wanted to defend her grandfather but didn't know what to say. Jiraya has one question which he asked;
JIRAYA: "You said that someone with MS released Kyubi 12 years ago, do you know anything about him?"
SASUKE: "I know few things about him, he always wears a spiral mask, no one knows his real identity but he is an Uchiha. He claims to be 'Madara Uchiha' but no one knows if it is true or not. He helped Itachi during Uchiha clan massacre, and later recruited him as member of Akatsuki. Everyone thinks that a guy name 'Pain' is the leader of Akatsuki but in reality it is that guy. 'Pain' is just a puppet manipulated by him. He has awakened his MS and it gives him very troublesome ability. If you attack him he will turn intangible, any attack will phase through him."
TSUNADE: "How do we deal with him if all our attack can't even touch him?"
SASUKE: "The moment he attacks you, he has to have his physical body in this plane. So you need to attack him at the exact moment he attacks you, but also your attack should be hidden, if he sees your attack coming, he will turn intangible. Another way is to attack him for more than five minutes without stop. He cannot remain intangible for more than five minutes. Make your strategy based on that."
JIRAYA: "Does Itachi told you about him?"
SASUKE: "He was the spy of leaf working for third Hokage. Do you want more information on Akatsuki?"
