Disclaimer : I don t own Naruto

**************************

Naruto was awake from a sound outside of his tent. Looking around hi found that it was around midnight. Knowing that he had the first watch he knew that he could refuse the sound and go to sleep, after all Anko sensei was for the second watch and if any problem happened he was sure that she would inform them in time. But from instinct he got out of his tent looking for the sound source. Anko was nowhere to be seen. He was worried about his sensei's well being so he started looking around for her. Some minutes later, a little far from the camp he found her sitting on the ground with one hand around her neck panting heavily.

"are you ok Anko-chan?"

"oh Naruto, don't worry it'll pass, just help me to walk to the camp."

Helping Anko with putting her arm around his neck and supporting her weight they went to camp. Sitting near the fire Naruto asked.

"Ano, Anko sensei, I never seen you in such a pain. What is the problem? Can I do anything to help you?"

"unfortunately you can't do anything Naruto. It's the curse mark that bastard gave me before cleaning my memories. He told me that this mark will give me the power and will make me powerful but god knows that it hurts like hell. I never feel power when it pulses like this just pain and pain. I don't know how to suppress it. Hokage sama helped me with putting a limitation seal around it. The seal reduces the pain but steel it's too much. But no worry, most of the time it passes in minutes."

"why did he gave this to you? Didn't he know the result? Wasn't you important to him?"

"well, I thought that I'm important to him but after all I was just another test subject in his eyes. He was developing this seal mark when he gave me this. He said that the research was finished and the mark is ready to be used by people. He told me that he'll gave it to those who is important to him. Bastard, I didn't know the meaning of being important for him."

"is there any way to remove it?"

"no. Hokage sama tried so many times and all the times he failed. We asked a Hyuuga to look and analyze the system. He informed us that the mark has strange chakra within it and it is pushing it in my chakra circulatory system. He informed us that if we will not be careful for removing the seal it can kill me. God knows how much I like to remove it but no one knows how. If I remember correctly the snake bastard told me that even he himself can't remove the seal. "

"well, I'll start to study about chakra seals soon and see if I can find a way to suppress the leakage of that chakra to your system. This should reduce the pain at least."

"honestly do you think that you can do something like that even when Hokage sama couldn't do much?"

"so you forget that I have a foxy queen sealed in me that has thousands of years of experience in all the things that any human being can imagine?"

"well, maybe this will bring a new hope, but I can't risk too much ok?"

"sure. I won't do things before being one hundred percent sure about the result. After all I'm not the stupid boy everyone see, it's just a role play and please keep it a secret to yourself ok?"

"thanks for trusting me to say secrets Naruto. Don't afraid I won't say it to anyone."

"Kit why did you say that to her? After all we don't know her completely and considering her mental state I'm not sure about her trust worthy."
'kyu-chan we need to start trusting to some others someday and we must start this sometime and with someone. Who is better than sensei who shares same problems with the village? A woman that is hated by most of the villagers for a reason that she has nothing to do with? If I can't trust her then who is the person that I should trust?`

"well I think I have nothing to say for that logic. You are growing very fast foxy."

'Thanks.'

"Ano, Anko sensei, if you want I can continue watch so go on and rest a little. After all I'm awake now and I don't think that I could sleep."

"Are you sure Naruto?"

"hai"

"ok. Wake me if any problem happened ok?"

"hai."

With that Anko gone to her tent for sleep. This was a perfect time for Naruto to open his library scroll and getting a scroll from it.

'well what kind of training I should start?'

"I think you can start looking for another jutsu from the secret scroll. After all you managed kage bunshin to its full potential so you can move on for another powerful jutsu."

'hmm, good idea. Now let's see what we have. Kage shuriken ninjutsu, may be this one will be nice to learn. It says a shinobi can shoot a shuriken and make needed hand signs changing one shuriken to as many shurikens as his chakra allows. Deciding of the name the base knowledge for this one must be like kage bunshin and considering my chakra amount this may be mean making thousands of shurikens just from one shuriken. What do you think kyu?'

"it's a nice jutsu. You definitely need an attack ninjutsu. And if you could combine this jutsu with your kage bunshin can you guess what will happen to your opponent?"

'he will be a bag of meat after that. No one should be able to survive after that'

"exactly and this is what I call a foxy boy"

'hehe. Now if I remember our conversation I can start learning it with the help of kage bunshin correct?'

"yah. And by using them I think you'll have mastered this jutsu in the morning. Now let's start the show"

'hai'

Naruto going a little far from the camp made 300 kage bunshins and started training for the kage shuriken nojutsu. The process was slow at first but after one hour he dismissed all his bunshins and having their knowledge started to test the jutsu. Now he found that he was mastered it half a way. Actually he could make more than 500 shurikens from one shuriken. The problem was that they were destroyed just when they hit target, now he was sure that by the morning he should mastered this jutsu because he knew exactly what he needed to make the jutsu to work; just putting more chakra to each shadow shuriken!

It was about two weeks now and Naruto was studying about seals that could store chakra in them. There was little resources and the material was too complex for him but he promised himself that he would finish learning them and helping Anko-chan.

'Aaaaaaaaaah it's too complex. How should I know where to start making a simple seal to store a little of chakra in it?'

"well I know a seal that can store a chakra to it but it's not like these seals you are looking to and it's not a big deal it's just for sealing chakra that is hanging in the air. Not a big deal as I said and I'm not sure if it can help you"

'well anything may help. How can you teach me?'

"we need to be in your mind so I can show you the shape and the knowledge behind it and the mechanism."

'ok no one is around and it's not my time for camp watch so let's start.'

Concentrating chakra to his core Naruto closed his eyes and after about a minute he was in front of the beautiful girl with red hair.

"ok. Sit and pay attention. This seal needs to be shaped like circle just like those storage seals. After all it's a kind of storage seal. Now come close and take a look. As you can see it has 5 lines going to the center and you must know that each line is for sealing one element of the chakra, one for wind, one for earth and so on. In the middle of the circle need to put another seal symbols again in circular shape. This new one will block the chakra to get out of the seal. You need to activate each circle in certain order depending of the process you need the seal to do. For example if you are sealing the chakra you must activate the outer circle then the lines to the center and when all the chakra was sealed you need to activate the central circle. When you want to release the chakra you must first deactivate the central circle and then deactivate the outer circle and the chakra will be pushed out to environment from the line channels automatically. Keep in mind that you can't use this system to store your chakra for later usage because as I said when you release it , it'll be vanished to environment around you."

'hmm, interesting. I can't figure the usage of this seal yet but I'm sure that it can be used later on when I think more about it. Thanks kyu. Now I'll go out and try it, can you look if I do it correctly and give comment when I'm out of here?'

"yah no problem foxy."

With that, Naruto came back to the real world and started shaping the seal, after half an hour trying he managed to make the seal and stored some of his chakra. And then released it. He found that no matter how much chakra he put in the seal, it'll be stable and do the job perfectly. He found an empty scroll and wrote the principles and mechanism and seal shapes and uses for this seal in it for recording it in his library calling it chakra storage seal.

##############################################

The mission finished with nothing more special to be said. After a month they changed post with new gennin team and went back to Hokage for mission reporting. When they finished reporting Naruto stayed beyond others.

"do you want to say anything Naruto? Are things all right?"

"nothing is bad Oji-san but I want to you to look to this seal. And say what you think. I have a theory but I'll tell you after your answer for the seal."

Then Naruto made a perfect chakra storage seal and stored some chakra in it, showing the Hokage all the process of sealing and unsealing he waited for his comment.

"well, the seal is not so complicated and it's easy and fast to make, yet I can see that it's well balanced and stable no matter how much chakra you put in it. But what is the usage of thing like this? Why anyone want to seal chakra in seal when they won't get it back when they release it?" asked Hokage wondering how Naruto managed to make such a good seal

"well, I'm sure you know Anko sensei's situation with that damn mark she has. I think this will help her, I just need to find a way to link this seal with the chakra that is gathered in that mark, then I could seal that chakra completely in seal and even with releasing the chakra it will vanish to environment meaning that it won't go back to Anko sensei. I just don't know how I must connect it to that damn chakra yet."

"Wow. You make me surprise Naruto. There is a way to connect any seal with any kind of chakra in any person or any object, wait a minute I'll be back." With that Hokage went to another room and after several minutes came back with 3 book.

"here, these are all books we have about seals in Konoha. I want you to start reading them by order. In the first book there is a complex that will allow you to connect things with any chakra in contact with complex. I want you to learn it. But you should not try your theory on any person before we test it so many times that make us sure it won't harm people ok?"

"HAI, THANKS OJI-SAN" yelled Naruto taking the books and running out of the room leaving a smiling surprised Hokage to his thoughts.
