As Kayle was talking with Maru, he finally noticed that someone had joined their conversation without even feeling his presence witch made him up a few meters out of surprise, before calming down as he recognized the voice.
Kayle: "Itachi! Stop with that... I already said that's not funny at all!"
Itachi had a little smirk at the corner of his lips as he enjoyed surprising Kayle, it even started to become a competition between him and Shisui.
Kayle turned around and saw Itachi wearing a black cloak with red clouds on it, his eyes were red with three tomoe while the middle was a sharp vertical line, and he had black marks around his eyes slowly fading, to reveal his natural appearance.
Kayle: "You... You... succeeded.. didn't you ?"
Itachi: "Yes it was more complicated than anticipated but I have complete mastery of it... Shisui can use it shortly but he didn't master it yet"
Kayle sighed out loud while looking at the sky, after saving the Uchiha clan, he kept regular contact with them, he met with Itachi almost every month and created a small organization while appointed Itachi as its leader, the organization's main purpose was to investigate the white Zetsu army and Madara, and it did a wonderful job at it.
Under Itachi leadership, almost all the Uchiha of the Jonin rank joined it, and they were slowly released out of the pocket dimension after passing several tests.
In only two years since its creation, they had managed to get significant results as we successfully found the location where the army of white Zetsu was being created and Madara's position.
Kayle: "How is Groot doing ?"
Itachi: "It's doing very good! as you requested our number one priority is to not get discovered, and except the small tree-man that we can make appear on our skin when using the Jutsu you created there is no way to connect us to the organization"
Kayle: "And what have you been working on lately"
Itachi: "Currently we have three projects, the first was the one you requested, we are searching for the location of every Jinshuriki or Biju, the second is to make us ready for the war, we augmented the difficulty odd the training in the forest of darkness and the last is about Orochimaru"
Kayle: "Good, proceed slowly with Orochimaru, there is no need to make a decision this quickly we already finished our first deal with him, let's give him some rest I don't want to change the future too much yet"
Itachi: "Noted, so tell me kayle, How is your progress with the forest of darkness Senjutsu?"
Kayle: "I've been training since I had the chakra of a Jonin and I did have some progress but I couldn't master it yet... it will take at least several months"
Itachi: "Well don't worry too much you have the Yin chakra affinity it will be a lot faster than me to master it"
Kayle: "...Itachi.. you really don't know how much of a genius you are... while you all Uchiha had a more than average compatibility with it, you still managed to master the Yin-Senjutsu in only three years even your father can't feel the natural energy yet..."
Itachi: "...I really don't think I'm that talented, you know it's quite easy to do, all you have to do is feel it, collect it and use the x2+y2−3z2−3t2=0 equation with x being the natural chakra, y the spiritual chakra, z the physical energy and t the duration to balance them"
Kayle: "..."
Maru: "Kayle? why aren't you this smart ?"
Kayle: "That's quite the stupid question, it's very simple it's because I'm a human"
Kayle sighed while thinking about the power he had behind him, he had already three Kage Ninjas, Itachi, Fugakou and Shisui, and his organization had around 20 Jonins.
Kayle: *Crouch and make circles with his fingers*
Kayle: "Where did things go wrong? am I not the main character? why is everyone so strong...?"
Maru: *Whistle*
Kayle: "Even if I finish learning Yin-Senjutsu I will only be around the same strength as Itachi... I'm pretty sure he will still be stronger"
Maru: "Common buddy.. all you wanted was a simple life..."
Kayle: "Yes but still... I don't know if I'm even needed..."
Itachi: "You are! Without you, we wouldn't be even able to access the pocket dimension..."
Kayle looked towards Maru as he felt even more depressed
