"There are five basic types into which the nature of chakra can be transformed, called the Five elements Nature Transformation ( Godai Seishitsu Henka). These five types are also called elements and are not only the origin of the names of the Five Great Shinobi Countries, but also the foundation of all elemental ninjutsu. The five basic natures are all connected to each other in a circle, each being weaker than one and stronger than the other. They are Fire, Water, Wind, Earth and Lightning." explained Naruto briefly
"Accurate as always, I trained you well."said Kakashi proudly, and Naruto nodded humbly.
"Every person has chakra that has an affinity towards one of these types, a characteristic that seems to be genetic, since whole clans sometimes share the same affinity. Most members of the Uzumaki Clan, for example, had an affinity towards the Water nature. They were one of the most skilled water users in the world whose skills surpassed even the Nidaime Hokage, who was said to be the most powerful water user of his time, he could convert the moisture in the surrounding environment and create water."said Kakashi briefly
"That's excellent, but what would happen if a person does not have the affinity for an element?" asked Naruto curiously
"Usually it would be extremely difficult for a person to master the ninjutsu of that element, as it is not his type and also it would require a lot of chakra. But it is not impossible a person could still learn a technique of the element which he does not have but it won't be very effective."explained Kakashi
"So how can I find out my element?" asked Naruto eagerly
"The paper which you have in your hand is a chakra paper, pieces of paper made from a special type of tree (that are grown and fed with chakra) that are used to react to even the slightest hint of chakra in any of a number of ways, depending on the nature latent in the chakra...
"If your affinity is fire it will burn, if your affinity is water it get wet/damp, if your affinity is earth it will crumble, if your affinity is wind it will be sliced and if your affinity is lightning it will wrinkle. Now channel your chakra into the paper, let's see what you got."explained Kakashi seriously
Naruto then channeled chakra into the paper, and the results were quite astonishing. At first the paper got damp, then it got sliced in half, but before it could reach the ground one half of it was burnt to ash while the other half wrinkled.
Kakashi eyes widened on seeing the results, he had expected Naruto to have two affinities at the most, but he had four natural affinities.
"That's impossible." thought Kakashi dumbly.
"Interesting" smirked Naruto proudly
"Nii-san, how do I have four affinities?" asked Naruto curiously, bringing kakashi out of his daze.
"I think its because of who you are Naruto, that you have these affinities." said Kakashi honestly
"What do you mean?'' asked Naruto confusedly
"It seems that your water affinity is the strongest out of all your affinities with wind rivaling it. Your paper got damp first, so you have a strong water affinity, also you have a strong affinity for fire and lightning. The reason I think for you having these affinities is because of your clan. You belong to the Uzumaki clan who were the strongest water users in the world, so you got water as your strongest affinity, as for your fire affinity the Uchiha clan's primary affinity was fire, so you gained that affinity as well. Your father had lightning affinity like me so you inherited that from him and as for your wind affinity I think it is your own." said Kakashi suggestively
"Okay Nii-san, but what was Tou-san like?" asked Naruto curiously
"Your father was one of the most talented and strongest shinobi of the world. He was also a very smart and kind man who cared for his friends and village."explained Kakashi also not giving any vital points about Minato's abilities.
"Thank you for telling me Nii-san, but will I be able to perform any earth techniques?" asked Naruto hopefully
"They won't be much efficient, but with hard work you could at least be able to perform it as an average jutsu."said Kakashi honestly, and Naruto nodded satisfied with the answer he got.
"Alright now as you have water as your strongest affinity I am going to teach you a water jutsu. It is called Mizu Bushin No Jutsu. It is similar to the Shadow Clone Technique, except it creates clones out of water that have one-tenth of the original person's power. Like other solid clone techniques, the clones can be used to perform tasks the user is unable or unwilling to do for themselves. The range of the clone is limited however, as it can not travel very far from the original body without losing control. Like other clone techniques, if the water clones are injured enough they will revert back to normal water. Now normally this technique requires a source of water but you will be able to perform it." explained Kakashi and showed naruto the hand seal
Naruto formed the Tiger seal and in a moment three identical water clones were formed.
"It seems I was right, you are able to convert the moisture in the air to water like Nidaime-sama, though you are not at all as great as he is with water manipulation but with a few years of training you will be. You are indeed a true Uzumaki." said Kakashi proudly, and Naruto bowed in return showing his appreciation to his brother.
"Nii-san, what rank was that jutsu?" asked Naruto curiously
