The 4th's Flying Thunder God Jutsu

After the Hokage left he also planned to go home and write down the jutsu and think about what he would like to ask the Hokage for. When he's near the house he could feel Sakura's chakra inside. He went inside ans was greeted by Sakura.

"Let me guess. You want me to train you because you want to be stronger?" Kuro who was asked awhile ago by Sasuke and Naruto already knew what Sakura wants.

"How did you know? but yeah I want you to teach me. Please? I want to stand beside them." Kuro smiled at this.

"Sigh fine fine, But I will only teach you until the start of the finals. I have a match to win 'ya know"

"that's totally fine, if Naruto could do it in 2 weeks then I can do it in a month." says sakura enthusiastically

'and that's where you are wrong. Naruto had shadow clones to make it faster. And I had to force feed(give him hell) it to him so he could just learn. While you don't have a lot of chakra but your control is better than him so I guess it will still have results'

"Then return here tomorrow after lunch since I have to go to the Hokage in the morning. Then I will explain to you the condition and how were gonna do it."

"Yes. Thanks Kuro. I'll see you tomorrow then" Kuro nodded. 'Hmp you'll be calling me sensei starting tomorrow! hehehe' Kuro grinned at the thought of being a sensei of the team 7.

Once Sakura was gone he prayed a little. No more visitors please! I don't need more. please.!

His prayer seemed to have been answered for a few hours until someone came again. It was his teammates and team Captain. They comforted him and he very much felt warm from them. Then in the middle of the talk he thought. 'I will definitely protect this'. Their little reunion last for a few hours and his team left him to himself.

'Great! the day's about to end and I haven't trained at all' says kuro

Kuro decided to work on the 2 Jutsu he's going to pass on to the village tomorrow. In the evening after he prepared the Justu he still decided to train and went out.

"Mom I'm going out for a bit. I won't stay late don't worry."

"Make sure you do what you young man. I'll be resting now so help yourself later when you're back."

"Yes mom, thanks"

He went to the forest where he showed the jutsu to the Hokage. He then took out the executioner's blade. 'show me what you can do' Kuro focused some chakra on the blade. He didn't use the fire element chakra but just the neutral one. The blade was now covered with chakra. 'If I remember correctly the samurai was able to send a chakra wave in the 4th war, will it be possible with this blade too?' Kuro tried to slash the blade horizontally from left to right but no chakra wave out. He tried it again and again by adjusting the amount but nothing seemed to happen.

After many failure he tried it vertically. He placed the blade by his shoulder and jumped. As he began falling he swung the blade with chakra, the sword fell but nothing came out. Due to the weight of the blade he was unable to stop it hitting the ground, and that's when the chakra burst out of the blade completely leaving it and shot forward. Kuro was in joy by what happened. He thought it wouldn't be possible but haven't considered having the blade in contact with a target only this time instead of the chakra just breaking the ground it also rushed out forward which was what kuro wanted to happen though he wanted an attack that flies. 'This much is enough, if I could further develop it maybe I could make it fly instead of just attacking from the ground. But, what if I use my fire element chakra? it's getting late might as well do it tomorrow.' Kuro wasn't in a hurry besides he needs rest for tomorrow.

The next day in the Hokage tower.

"And so Danzo do you understand? you cannot recruit him since he made a contribution to the village."

"Hmmph, He would have been perfect for the root." Danzo who was with the Hokage when kuro came left the room.

"So kuro kun, Have you decided what you want for the other jutsu?" asked the Hokage

"Yes I've been thinking about it and, I've thought of what would further help me. I'd like to have a chance to view the 4th's flying thunder God Jutsu or the 2nd's whichever is more accessible for me"

'this boy never ceases to amaze me everytime. But his request this time. what to do'

"So it's not possible? Hokage sama?" Asked kuro who was waiting for an answer and was wondering why the Hokage was silent.

"Don't worry it is possible. However you will only be able to view it once. It's on a forbidden scroll after all. And also I will let you view both the 2nd and the 4th's work so I can be sure you have all the information you need. Study of this Jutsu is very dangerous that's why it's forbidden. We don't know what accidents may occur and we don't want to loose you because of it. Do you still want to proceed?"

"How long will you let met study it? and also, Is it possible to make a copy of it or at least write down what I've learned so I can revisit in case I hit a wall?" Even though kuro is certain to memorize all of it but he is not sure if he'll be able to understand it completely. The only reason why he arrived with this decision was to further development his ability to phase through, although it's not as powerful as obito's currently. If he could develop it, to be able to teleport then that would add as another weapon in his arsenal.

"You have a until lunch to be able to view it today. You cannot copy it but you are allowed to write down what you've learned. However you can only access what you've write down once a day right here inside the Hokage building with my supervision. Will this be satisfactory kuro kun?"

"That's more than enough Hokage sama!" kuro was excited to know the decision. And so the Hokage prepared another room where he can study the scrolls all he wants until lunch. Once the time was up and the Hokage retrieved the scrolls, he was surprised how kuro was able to write down a lot of scrolls with the given time period.

"Kuro kun, may I know how you were able to write down this many? although it's understandable for you to have learned a lot but I don't think the time was enough for you to write this all at the same time." the Hokage was curious

"Well Hokage sama, I will only tell you if you're willing to give me another favor. Afterall if I tell you the answer it will also help you with all your paperwork. ehehehe" kuro just got an idea and had an evil grin. it's like he got the Hokage in his hands.

"Really? How will I know you're not just trying to fool me?" the Hokage was almost hooked but calmly ask.

"Well how about this. I will tell you the answer. If the answer proves I'm right that it will help you also with your paperwork then I can have another favor. But if it clearly does not. Then its okay not to give me another favor. how about it?" and the trap was set

"I accept. If it really does help me then what's there for another favor. And if it does not, then I got nothing to loose i will at least have my answer from you"

"I used shadow clones Hokage sama. I'm pretty sure it will help you a lot with your paperwork. Shadow clones is the answer" Says kuro as a matter of factly

the Hokage's mouth wide open.

. . . . . . . . . . . . . . .

'sigh this kid sure has a lot of tricks up his sleeve. it's making me wonder why we haven't thought of this before'

"Alright let's get this all done today. What favor will you ask this time?"

"Did you know my teammates entered the exam for me? right now I'm the only member besides my captain in our team."

"Yes I have received their retirement forms. what does this have to do with your favor?"

"hehe I would like to have a few years off after the exam to develop my Jutsus."

"Years? that's a lot. I can give you months but not years."

"at least 5 years Hokage sama?

"No, I can give you 8 months"

"4 years?"

"10 months!"

"3 years?"

"1 year and that's the longest I van give you! anymore and you can ask for another favor!"

"the I better take it Hokage sama. Thank you!"

the Hokage was worn out. 'Boy you're totally reducing my years.!'

"Well then Hokage sama, I will return at least 3 times a week to revisit all of this that I've written down. after a month we can erase them. I better return back, I don't want to be late for my student."

"Hmmn student? you're going to teach another one besides Naruto?" Hiruzen got curious

"Well yeah. Sakura came to my house yesterday after you left and asked me to train her." kuro didn't hide who he's going to train.

"well if that's Sakura's decision then you must do your best to help your friend."

"ofcourse! then I'll be off Hokage sama" kuro left the worn out Hokage alone.

After lunch, Sakura came to his house.

"Kuro san im ready! let's train, please guide me."

"Drop the san, from now on you will call me sensei. It's my only condition for you. Now quick question, how many shadow clones can you make?" kuro asked with an evil grin. Sakura had a bad feeling at kuro's look

"I can make 5 clones, why? you look scary please stop that." Sakura was beginning to regret asking kuro

"Oh sorry sakura but we have limited time. So I have to be as efficient as possible hehe"

And kuro started the training with his clone to train Sakura, he also used a clone to go to the Hokage's building for follow up on the study of the flying thunder God jutsu. while the main kuro is developing a jutsu that fit the executioner's blade along with his flame chakra. This was the routine of kuro for a month before the finals of the Chunin exam.
