Chapter 26: Elemental Jutsus

Disclaimer: Naruto is the work of Kishimoto

Naruto in a nutshell was worried about this mission.

Aside from the fact that he needed to protect a set of civilians no matter what, possibly bring a country out of the hands of a tyrant and face off Haku who apparently had the ability to use Ice Ninjutsu; Naruto had a lot to prepare for.

But the guise of things on one perspective is that Naruto needed to get stronger. However the truth is that he needed 'Time' to get stronger which being stuck in a Time Loop doesn't help. His Chakra may grow as large as it can but in the end he is limited to what his physical body could handle.

Therefor Naruto needed other tools to use in order to counter what he has to face.

He counted off the things he needed to keep track up, 'Unknown enemy wanting to kidnap/kill Tazuna's family, mercenaries Gato hired, other possible enemy ninjas, Zabuza and Haku…god this list better not get longer. I can't keep track of all of this and protect everyone!'

While it was highly difficult, Naruto could see a way to help Wave enough and make sure at least most of the innocent people in this country are saved.

But to do that he still needed a way to beat Haku and maybe Zabuza if Kakashi loses to him.

Moving on after that problem, Naruto needed a way to take away the control Gato has over the country. Making a big ass bridge was one thing but it was completely another if Gato just destroys it or even take over it and use it to make more of a profit with tariff.

This meant that Gato needed to really die since Naruto couldn't see a way on making sure Gato didn't have revenge on Wave or himself later on down the line. Naruto shook his head because he was actually thinking of an assassination on a multi-billionaire who lives in a fortress with countless guards around and possible ninjas as well.

Though Naruto was mentally 2 years older than his peers now, it was still sad for a 14 year old (Even mentally) to think about these things…or was it expected since at that age a Ninja has enough experience to be a Chunin at least.

But his body was still of a 12 year old and it would take him a lot of work to get it up to Chunin levels physically without Chakra boosting his specs. He was just starting to hit puberty and thanks to the proper food other than the occasional god-like Ramen, he was no longer the shortest male that came out of his Academy class.

But that didn't change that Naruto had no real strength aside from spamming Shadow Clones.

For all its worth, such tactics may have worked against the average ninja, against the skilled it was pretty useless especially those like Haku who had speed and even had weapons that could quickly hit you faster than you could think.

Basically Haku was ironically the bane of his Shadow Clones.

Naruto wanted to start learning more Elemental Jutsus to counter this weakness that the current Naruto has. There were several ways Naruto could see how he could possibly counter Haku. The first was simply to take her out of the equation altogether, but that was impossible and he didn't want to assassinate someone he could consider a half-friend.

With second of course was with Fuinjutsu but that would take years' worth of Looping to get to a good level to counter a most likely Bloodline she processed. From there Naruto moved onto the next most feasible option.

Ninjutsu.

Elemental Ninjutsu.

He currently only had two under his belt and both of them were more designed towards enemies that were slower than him. The Earth Style: Underground Projection Fish Jutsu was a useful one to travel underground but when he hit rock…or even harder the control needed for the Jutsu shot up several times. That was the reason why Naruto couldn't use it on the bridge, he lacked the control to do it outside of battle which meant in no way he was going to be able to use it in battle.

Then there was the Earth Style: Double Suicide Decapitation Jutsu which was useful in trapping people with the exception of those who were good at using Lightning Chakra to conduct it around their body to break the Jutsu.

While possibly useful against other enemies especially with Shadow Clones to the point he may drag an entire army into the ground (That is, if they're not chakra sensitive which most Ninjas are), it was not at all useful against Haku.

Not that he was blaming Kakashi for it.

Those two Jutsus are useful to have but it won't win him the current fight. Which meant that he needed more Jutsus to use and combine with his ability to send out waves of Shadow Clones. And Naruto knew which two Jutsus he wanted to learn from Kakashi, else Sasuke.

Fire Style: Grand Fireball Jutsu.

Fire Style: Phoenix Fire Jutsu.

These two Jutsus are counters to Haku's Ice Style Jutsus though is effectiveness would be admittedly reduced thanks to the mist and the water that's all around them during the battle. Plus it would be good time to actually start practising those methods to improve his Fire Affinity that he copied from the Konoha Library and got off Sasuke that time back.

Taking a scroll from his side, Naruto unsealed it and took out a further two more scrolls on the matters involving Fire Jutsu and started to read them.

The Fire Style or Fire Release is one of the basic elemental nature transformations (Read Nature Transformation for Beginners).

Naruto stopped there, "Huh, might as well read that first just in case then" he muttered before taking out the scroll describing Nature Transformation and Elemental Affinity which he also copied from the Konoha Library.

Nature Transformation is an advanced Chakra Control that entrails the molding and defining of one's Chakra into an innate kind of Chakra Nature, altering its properties and characteristics for use in Jutsus. This along with Shape Transformation (Read Shape Transformation for Beginners)-

"Drat, another thing I have to read" Naruto sighed. He didn't have anything about Shape Transformation since he didn't even know it existed! He placed that into the mental pile to remember to look up later on.

-are the two necessary components for creating or modifying a Jutsu.

"Okay it relates to stuff that sounds like a good future project at least."

The Five Element Nature Transformations are the most fundamental Chakra Natures, which are the foundations of all elemental Ninjutsus. They are vital to the point that each of the Five Shinobi Nations are named after them as well due to a high ratio of Shinobi in each Village having an affinity to those Elements.

The standard relationship between each Element can be summed up as following.

Fire is strong against Wind but weak against Water.

Wind is strong against Lightning but weak against Fire.

Lightning is strong against Earth but weak against Wind.

Earth is strong against Water but weak against Lightning.

Water is strong against Fire but weak against Earth.

However just because one Element is inheritably stronger than another, it does not mean that a Jutsu that is by nature is weaker than another Jutsu cannot overcome them. Basically if an Elemental Jutsu is put up with another Elemental Jutsu of the same level, the one with a stronger Nature will win else with they are neutral to each other they will stalemate.

Furthermore there are several key conditions in which an Elemetal Jutsu that is by Nature is weaker than another can win. The First is simply that the Jutsu in question has more power, mostly due to more Chakra being pumped into the Jutsu. In cases like these, say a Fire and Water Jutsu clashing, if the Fire Jutsu is strong enough, the Water Jutsu will be defeated and turn into Steam as a side effect.

Another Condition could be that a Jutsu would be boosted in power by another Jutsu so that it is of a higher level with a complimentary Element. An example of this is with a Fire Jutsu being boosted in power by a Wind Jutsu. This method will often provide effects that are more powerful than simply using two Jutsus of the same Element.

Finally, the last condition would be the battlefield itself. Elemental Jutsus are affected by the environments they are used in and due to this, Water Jutsus are difficult to use in a Desert, Fire Jutsus are weakened in places with mist and moist and so on. Given the effects of this, unless the user is prepared to use a higher degree of Chakra to use said Jutsus even in such environments, said Jutsus will often weaken else strengthened.

A similar principle will also apply to the first condition of Jutsus of the same power and level to Jutsus of the same Element. In the case where two Jutsus of the same Element and power clash, they will cancel each other out. However if two Jutsus are of different power levels, the weaker one will not only lose but will also be consumed by the stronger Jutsu and become more powerful.

This effect is similar to the environmental effect on Jutsus where said Jutsus have more materials to use and thus cost less Chakra to activate, but since the Jutsu is in place with an already amount of Chakra consumed, the Jutsu can only grow stronger when the costs of the Jutsu is once again decreased thanks to the opposing and weaker Jutsu.

However please note that there are some exception to this regardless of how much Chakra and power you place in a Jutsu. There are some Jutsus and otherwise stated that are absolute in the hierarchy of an Element. The only confirmed example to Konoha would be the Uchiha Clan's secret Jutsu: Amaterasu that will consume lesser flame easily even if it's a fraction of the power of the other.

'Huh, Sasuke's Clan has such a thing?' Naruto then remembered Itachi and how he was still alive and most likely had this kind of Jutsu under his belt and shuddered. He would need to think of a way to counter that.

However right now Naruto moved onto the Affinity side of Nature Transformation.

Elemental Affinity or Nature Affinity is the term for the Elemental Nature Transformation that each person is most in tune to. In general, every person's Chakra has an affinity to one of the Five Basic Nature Transformations. An Affinity can at times be genetic (In the case of Bloodline Limits), or at least common to a particular family where each member inherited a trait towards one Affinity.

In order to find one's Elemental Affinity, they must use one of several methods that are sensitive enough to Chakra that they affect such objects in relation to each Element. Chakra Paper is the most common practise and the cheapest among methods. Below are the results of each Elemental Affinity.

Fire: The Paper will ignite and turn to Ash.

Wind: The Paper will split in two.

Lightning: The Paper will wrinkle.

Earth: The Paper will turn to dirt and crumble away.

Water: The Paper will be wet and damp.

While normally a Ninja may have one Nature Affinity, there are cases where they have more than one. Such examples often involve Bloodline Limits in which a person may have two Elements to combine into a new one. However there are those rare enough to have two Nature Affinity at the same time and even rarer to have three at the beginning.

Much research have shown those with the rare multiple Nature Affinity often have defects or irregularity in one area or another due to the clashing compatibility between Chakra Natures where one Chakra Nature in the body may attempt to consume another weaker Chakra Nature to it. The only exception to this are with Bloodline Limits which can perfectly balance and combine Elemental Chakra perfectly and if said Nature Affinities are neutral to each other. Due to NO Bloodline Limit associating with three Elements at once exist naturally, those with Three Nature Affinities while rare, even rarer live a long life due to this imbalance in the natural state of their Affinities.

Please note that if you have mastered another Element other than your Nature Affinity, it will NOT show up on the Chakra Paper when testing. While any other Element may be brought up to the same level as your Nature Affinity, your Chakra will ALWAYS be in tune with your Nature Affinity over any other Chakra Nature Affinity.

Training your Nature Affinity can occur in two or more stages in which you gradually use your Chakra transformed into Nature Chakra of your choice to achieve certain tasks on higher and higher levels of power.

It is possible to train up all Five Elemental Nature Affinity but for each succussive Element trained, the time and difficulty on training the next will increase while the Nature Affinity that is stronger than your own Nature Affinity will always be the hardest to train.

Processing all off this…Naruto basically summed it up that ninjas can turn their chakra to use in Jutsus and the better they are in doing so, the stronger their Jutsus will be. Then there's that stuff with Nature Affinities which Naruto summed up as you have one, maybe two and those are the best elements you can use.

Yeah…so in the end Naruto learnt more about Nature Transformation and how they worked but not how to train them.

Damn.

Hopefully the scroll Sasuke gave him had some ideas on how to train his Fire Affinity at least. He probably needed to use a lot of power to counter Haku's ice from how quickly it formed and how easily as well.

The Fire Style or Fire Release is one of the basic elemental nature transformations (Read Nature Transformation for Beginners). It is performed by molding superheated Chakra inside the stomach before releasing it via the lungs and mouth.

Fire Jutsus work in the manner of Fire Chakra being converted into a catalyse in the stomach that is laced with Chakra to prevent harm from coming to the user when performing the Jutsu, in one breath this converted catalyse made from Fire Chakra is pushed forward out of the mouth at the same time as the air in the lungs which is the fuel for the Jutsu. Both aspects will interact with each other in the throat before turning into flames that depending on the Jutsu will automatically form by the time the flames reach the mouth where the user is able to adjust the output and shape of the coming out of the body.

While there are some Fire Jutsus that allow for the manipulation of Fire outside the body, they are uncommon and even rarer to use let alone use. There are also variants to this in the form of some mediums such as the use of gun powder, ash, explosive tags and chakra flow into a weapon. However it remains that using such methods in accordance to the nature of Fire Chakra will corrode the medium used whether quickly or with time and use.

The Fire Style is commonly affiliated with the Tiger Hand-Seal in which causes the Chakra to expand rapidly in its use allowing for the majority of Fire Jutsus to be combustive and highly explosive in nature.

In order to train your Fire Affinity, there are several methods you could use. The first is the standard 'Leaf Exercise' in that you are to recreate the effects of an Element on Chakra Paper onto a single Leaf. The faster you achieve this effect, the faster you are able to convert your Chakra into a Nature Chakra Type. After completion, you are to move onto larger and more fire resistance items.

The second method is much stranger and more difficult to gasp in that you are required to go to a location with a high amount of Fire Chakra naturally in the environment such as a Volcano. Upon there, you are to tune your Chakra to the Fire Chakra to take up its nature. Be warned that it is ill advised to use this method if your Nature Affinity is not Fire and especially if your Nature Affinity is not neutral to Fire.

The scroll continued on with how to use Fire Jutsus properly and how to see signs on how to improve them, how to coat your Chakra in places the Jutsu takes place to not take damage, what methods there are to 'change' the different types of form a Fire Jutsu may have.

Apparently most Fire Jutsus can be used in two ways.

Compressed damage or wide-spread damage.

Naruto had seen Sasuke use both the Grand Fireball Jutsu and Phoenix Fire Jutsu but didn't know there were different forms to them. The Grand Fireball Jutsu may be compressed into a raging ball of fire for maximum damage but can also be used in a wide-spread blast of fire like a flamethrower.

Meanwhile the Phoenix Fire Jutsu could be used to shoot multiple shots at the same time but it could also be used to rapidly spit out Fireballs in a linear fashion like a torrent. Doing so would increase its power over a single target enemy if you could hit them that many times.

Hell there were probably other methods on using said Jutsus that Naruto was not aware of.

But first he needed to a) Learn said Jutsus and b) Train his Fire Affinity to make it stronger.

By that point, Naruto already realised it was night and that Kakashi would be awake the next day for Naruto bother else he would need to get Sasuke with some well-placed bribes to get stronger as an exchange.

"You want to learn what?!" Sasuke almost believed that his ears weren't working properly for a moment.

Naruto sighed and wondered if this was the reaction that Sasuke had every time someone asked him to learn a couple of C-rank Jutsus from him that he had used in a previous battle.

"I want to learn the Grand Fireball Jutsu and Phoenix Fire Jutsu" Naruto repeated though this time a bit slower for Sasuke's sake at least. That amount of inbreeding in his clan apparently had its effects on his mind if he couldn't comprehend this.

But then again, the Uchiha Clan might have regulated marriages to prevent this, he didn't know the working of a clan as large as that.

"Why?!" Sasuke asked again causing Naruto to be a bit disappointed in him though it was completely understandable. Surely the great Uchiha would know…

Well he was still stuck as a 12 year old avenger compared to Naruto who was mentally 14 years old now and had a hell lot more experience than Sasuke in fighting strong foes such as Zabuza. Scratching the back of his head Naruto merely grinned before pausing and putting on a serious expression.

"Because I need something more than just Shadow Clones and what else I currently have in a fight" Naruto explained, "I simply lack power to take down enemies. You can block a dozen or a hundred Shadow Clones with ease but you have to dodge a giant Fireball because it is more harmful to enemies than merely having a hundred or thousand copies of myself pounding on a single person."

Sasuke stared at Naruto in disbelief before saying, "So what do you have that may benefit me?"

Naruto only grinned thinking of all those exercises he learnt from Kakashi from the previous loops that he could use as a bargaining chip to Sasuke.

-Break-

The actual learning of both Fire Jutsus from Sasuke was surprisingly easy for Naruto. Mainly because it was all about power first and control second he noted. He learnt the hand-seals for both Jutsus from Sasuke (who did not bother to reduce the number of hand-seals from what he could tell) and went his own way as Sasuke trained himself to exhaustion.

Right now Naruto was having Shadow Clones do most of the hard work and get the control down for the Jutsu. Like any Jutsu, failing to execute it may vary from nothing happening to things that you wished didn't happen to you.

Seeing the results as his Shadow Clones were popped by being burnt from the inside out was a good enough reason for Naruto. The current result was there was a 90% chance of Naruto burning up his insides if he dared tried to use even the Grand Fireball Jutsu currently. The Phoenix Fire Jutsu was even worse where none of the Shadow Clones could manage to use that without being destroyed easily.

Naruto signalled for the remaining Shadow Clone to dispel so he gained their memories.

"Got it Boss" the Shadow Clone saluted to Naruto before disappearing causing Naruto to gain the knowledge to somewhat not harm himself while executing the Jutsu.

With another sigh Naruto made a cross hand-seal and said, "Shadow Clone Jutsu" causing another 10 Shadow Clones to appear replacing the previous ones.

"Right, execute the Jutsu!" Naruto barked out, "Focus on safety first. Size and power comes after we figure out a way to NOT burn up inside."

"YOSH!"

A collection of 10 voices screamed out before forming the hand-seals rapidly and shouting out at the same time, "Fire Style: Grand Fireball Jutsu!"

BOOM!

And all but three Shadow Clones this time popped due to using too much chakra as a fuel and too little to protect the insides of their body. Looking at the…remains of the ground that they stood at, Naruto could only think that his Shadow Clones were stupid…until the memories came in.

"Damn…" he sighed, "Still using too much Chakra."

He really cursed his lack of Chakra Control even now. However it may just be that he needed to be a lot more familiar with the Jutsu to use it, else there may be some other problem that he hadn't realised yet.

Meh, he would figure it out later.

Dispelling the rest of the Shadow Clones, Naruto continued on recreating more Shadow Clones to execute the Jutsu and absorb the information and knowledge that they gained with the Jutsu. It seemed that getting the right amount of Chakra to coat the inside of his stomach was harder than he thought.

If he used too little, he would get burnt.

Too much and he would create a wall of Chakra around his stomach to the point it actually contains the fuel for the Jutsu and with the increased pressure would literally explode from the inside.

'Only would I have such a problem that may explode me if I fail…' Naruto cursed continuing this exercise as many times as possible with his Shadow Clones as he, the original tried to relax using Chakra Control to make leaves dance around him slowly trying to pass the time.

Several hours later and several hundred Shadow Clones, Naruto let out a scream of frustration.

"Why can't I get this right?!" he roared to no one in particular.

To what seemed to have hundreds if not thousands of times he used the Jutsu even indirectly with Shadow Clones, he never seemed to go higher than a mere 50% chance of the Jutsu working. He even got the shape and size of the Jutsu down correctly, hell he even cut down the hand-seals required to 4, but there was still a good chance he would harm himself while using the Jutsu.

"I really must be missing something…" Naruto assured himself.

Then again, it all probably had to do with his Affinity which he didn't know yet. He should talk to Kakashi about that.

-Break-

"So you're trying to learn Fire Jutsus?" Kakashi to his own only looked mildly surprised at Naruto when he explained his problem to him. It was one thing to have one student that already knew Chunin level Jutsus but another when a second student was trying to do the same.

Though that said second student already had a Jonin Jutsu and its Kinjutsu variant already.

But then there was a clear problem that Naruto didn't seem to see, "If you had that much trouble that you came to me, why didn't you follow the instructions and try to raise your Fire Nature Affinity first? Though you should've came to me either way if you were learning a new Jutsu, especially an Elemental Jutsu."

Kakashi gave a disappointed look to Naruto causing the blonde to look away in shame.

"But I'm still impressed that you used Shadow Clones to scope out what you needed to improve using the Grand Fireball Jutsu" Kakashi eye-smiled at him, "I'm just glad that you used that method and didn't injured yourself."

"Haha, I knew better than to just try to use it with my Chakra Control. I'm still trying to raise it up with some Techniques I learnt but haven't mastered yet" Naruto said grinning before flashing his Chakra and compressing it before letting it go.

"Hmm…" Kakashi wondered what kind of techniques that Naruto learnt to do this. As far as he knew, Naruto didn't know any more advanced Chakra Control techniques higher than Water-Walking.

Well it didn't matter right now since Naruto seemed to have it under control as long as he used his Shadow Clones to help him out and prevent himself from doing permanent damage to himself. Right now Kakashi needed to at least solve this rather minor problem Naruto had using Fire Jutsus.

"Okay what do you know about Nature Transformation and Nature Affinities?" Kakashi asked.

Naruto looking at his Sensei strangely recounted the information that he had gained from the scrolls and even about how to use Fire Jutsus properly as well.

This caused Kakashi to be surprised since such information were for those at least Chunin in the village. Information that while may boaster the strength of the lower ranks would cause more trouble than it was worth.

There was a good reason why most Genin didn't know Elemental Jutsus.

Thinking quickly on what Naruto had told him, he recalled the facts.

1) Naruto was having trouble with Fire Jutsus which meant his Nature Affinity wasn't Fire

2) This meant that his Nature Affinity was one directly linked to Fire which was Water or Wind

3) Seeing that Naruto had no trouble with Earth Jutsus, this left Wind as his Nature Affinity

But then again, Kakashi needed to check if Naruto just had particularly strong Water Affinity since while it is difficult to learn the Element that your Nature Affinity was weak against, learning the Element your Nature Affinity is stronger is also more difficult than normal but not to the extent of the former.

That was the reason why he had a hell of a time learning Earth Jutsus and even Wind Jutsus though he found the former too convenient to use than anything else being the only Defensive Natured Element.

But first he needed to check Naruto's Nature Affinity to make sure.

Taking out a piece of squared paper he handed it to Naruto who looked puzzled until he explained, "This is Chakra Paper and while it cannot determine the more detailed analyse on how compatible you are with each Element, it can still determine which one is strongest."

He took out a piece and pushed his Chakra into it causing it to wrinkle from the centre.

"Right, hopefully this can tell me why I suck at Fire Jutsus" Naruto grinned and then pressed a small, yes small for Naruto that is, amount of Chakra into the paper causing it to split in two quite clearly.

Unfortunately Chakra Paper also couldn't determine how powerful of an Affinity you had as well…unless you were really weak in all areas or didn't use much Chakra into the paper.

"Wind…eh?" Naruto had this strange look but Kakashi dismissed it thinking on how he was going to explain someone's Affinity strength without giving out knowledge only Jonins may have.

Wind.

That was the Element that his Nature Affinity was most dominant in and explained a lot on why he sucked at Fire Jutsus. Not that he wasn't going to at least master both the Grand Fireball and Phoenix Fire Jutsus.

Now to train himself so his apparent weakness in the Fire Affinity department doesn't slow him down. Kakashi had explained to him about while his Primary Element will always be Wind, he could easily train and master his other Elements as well.

The Shodaime Hokage, The Nidaime Hokage, The Sandaime Hokage and even Kakashi Hatake were able to master all Five Elements.

And all it took was hard work and time.

And time something he didn't need to worry about.

A/N:

This is the part which I was waiting for for a long time for.

The part where Naruto starts to literally outstrip everyone else in due to the sheer amount of Chakra he has and the time he has to spend refining everything to be so much better.

Yep, from now on, Naruto will be able to learn new Ninjutsu (Yaaaaaay!)

But at the same time while I was researching possible Jutsus that Naruto would learn (At this stage he would at best get C-rank Jutsus), I had to put into question on his Nature Affinity and how it affected his learning.

Part of this chapter was based off the information off Naruto Wiki and it was quite descriptive already of how Nature Transformation worked and how Nature Affinity affected it.

I juts added a couple points here and there that weren't on the wiki to make it more precise to me.

I really don't want to rehash what I wrote in the chapter so I'm going to talk about something else that's not mention in the chapter yet but rather the next one as a slight preview if you may.

Basically Naruto will suck at both Lightning and Fire Jutsus. The former to a high extent but also the latter in a lesser extent. The reason being? Naruto's Wind Affinity affects both Fire and Lightning on the chart.

Generally a Lightning user is bad at Earth, Earth is bad at Water, Water is bad at Fire, Fire and bad at Wind and Wind is bad at Lightning in a cycle which is based off the information that your affinity is too dominant that you won't be able to use the Element that your affinity beats.

However what about the reverse?

For certain a Lightning user won't be good at Wind, Wind won't be good at Fire and so on but are they generally neutral at using those Jutsus as well?

I mean on on hand you have one affinity dominating one element since its stronger while doing nothing for the element its weak against?

That doesn't make sense to me.

And so I made it so that your affinity to the elements next to your own are worse than the other two elements. Basically a double negative connection though one is clearly weaker than the latter.

And this becomes even worse when you have Bloodline Limits thrown in as well. Take Haku with his Ice Affinity which comes from his Wind and Water Affinities. In between the two affinity is his/her Fire Affinity.

In one scenario where affinities really only affect one other affinity for some reason, Haku would literally have a neutral affinity to Fire. Haku, Ice Affinity being neutral to Fire. Yeah, like hell that would happen.

In my method where both sides of an affinity gets worse, Haku's worse affinity would be Fire and he/she would be also bad at Lightning and Earth as well due to her Affinities connecting to them as well.

Sure, there are many theories in fics that say that the proportion of your nature affinity is different for each person so they can be good at so and so element even if their natural affinity is connected to it. That may be as well true but nothing in Canon says that.

Though the theory side on things Naruto is really bad at them in Canon anyway.

But here, I'm generalising and not making Naruto the exception to this. In fact, its even worse for Naruto since he has a strong Wind Affinity. Due to this, he will have trouble in controlling both Fire and Lightning Jutsus.

However there are really some exception to this rule.

Kakashi for one has a strong Lightning Affinity which means he's bad at both Earth and Wind Jutsus and more on the former. But the second most used Element he uses is Earth.

How does this work?

Well...Kakashi is one of those rare people who actually mastered all Five Elements.

Therefore any negative reactions he may have with the Element originally would be negated away since he mastered the bloody element. You may suck at the Transformation Jutsu for one but you won't suck at it when you master it. The same logic is placed here.

And while Kakashi may never be as good as any element than his Lightning one, he at the same time won't suck at every other element he knows and uses.

Another thing.

For those who someone get it in their heads that Chakra Paper shows every Element and Affinity for some bloody reason, it doesn't.

It shows a person's Natural Affinity meaning the Element they are most aligned to naturally.

Any other element or affinity they master aside from their natural one will not show up no matter what they do to the paper. Why do you think Kakashi's paper only showed his Lightning Affinity when he mastered all Five of them?

The only exception from this is probably due to a person's bloodline that may show two at once.

The Dust Release doesn't count since that's not technically a bloodline but rather a Jutsu passed down.

Rinnegan may show up with all Five Elements since that master of all elements thing.

Naruto's Six Path Mode? No idea there, maybe make the chakra paper explode into colourful pieces? No idea what happens there since he technically has every affinity as well.

Yeah, so that's my part here.

Also I'm still writing chapter 28 at this moment (Blame the fact that I usually write on my laptop. The keyboards from my laptop and my comp are completely different) but I can post chapter 27 soon enough when I edit it.
