No longer having Obito’s Sharingan was a loss. A disadvantage that left Kakashi more vulnerable. Unable to fight as well as he had during the fourth great shinobi war, and incapable of being made the new Hokage of Konoha.

That’s just a few of the rumours that Kakashi had heard whispered around the village since his appointment as Hokage. Judgements that had been a part of his life since his father had been shunned when he was a child. Forever growing and changing as the years went by.

Except for this time, there was no truth to the rumours.

The things being said about him were factually wrong, and the only people who believed them and passed them onto the next person were civilians. Those who had no real idea how chakra worked. Who didn’t know what a strain on his chakra reserves the Sharingan had been?

They would know better of course if they saw Kakashi in action. If they just happened to pass by the training field near the Hokage’s residence at moments like this. When Kakashi was in the midst of his daily training, his Anbu guards were hidden away in the tree lines watching over him as always.

Just five minutes of watching Kakashi would tell them everything they needed to know about just how the loss of Obito’s Sharingan had affected him. How much more he could do without the Sharingan constantly eating away at his chakra reserves, even when he wasn’t using it.

Then of course, if too many people were watching he wouldn’t be able to train with the same intensity. Creating a new Jutsu was always a dangerous activity. Not knowing exactly what it was he would get as a result meant that he could accidentally end up hurting someone who was a little too close when he made his next attempt. Plus Kakashi just wasn’t someone who enjoyed being watched. Anbu operatives he could forget about. It was their job to go unnoticed, even if he could still feel their presence. But civilians didn’t know how to hideaway. They’d stand out in the open gawking and whispering among each other. Disrupting his concentration.

It was better than he was able to focus. He’d be able to get it right faster if he was able to keep working uninterrupted. That was, of course, if he managed to get anywhere at all.

“It’s still not right,” Examining the mud wall that he had produced, Kakashi sighed. The goal was to create something stronger than the standard mud wall Jutsu. Something that would be able to withstand more abuse without breaking down. Yet no matter how he changed the hand signs that he weaved, or how much Chakra he tried to focus into the Jutsu, nothing had changed yet. It was a larger mud wall Jutsu, and the dogs that appeared in his Jutsu specifically were still present, but other than that it was still made of the same weak material. “Maybe if I try it one more time and focus a bit more chakra into it. I’m sure with just a little bit more effort…”

There were at least three more solid attempts left in him before his chakra reserves became dangerously depleted. Not quite putting him in danger of being bedridden with chakra exhaustion, but enough to put him on his ass for the rest of the night and tomorrow if he pushed a little too hard.

“Two more tries,” he decided, turning his attention back to the wall that he had already created. When he brought forth the next one, this one would crumble apart under the strain created when the new one was formed underneath it. He had already seen so many of his attempts crumble away as if they were nothing.

A constant reminder of why he was trying to create this new Jutsu. To build a stronger wall that would hold more strain. One that would keep standing, even if he tried to build another wall under it.

“You look like you’re thinking hard,” Turning his head, Kakashi felt all of the pent-up stress washing out of his body at the sight of that stunning, toothy grin that Gai always had on his face. “Genma said you’ve been training since lunchtime. I think it’s time for a break, don’t you?”

Gemma, the traitor. He was going to have to have a talk with his friend about telling about him Gai.

“Mah, you act as if I’m about to collapse at any moment,” reaching his hands up into the air, he stretched his body up towards the sky and watched as Gai maneuvered his wheelchair over the grassy field towards him. “Speaking of relaxing. You haven’t been-“

“You know me, Rival,” Gai cut him off, his smile only growing when Kakashi narrowed his eyes. “Just because I require a wheelchair to get around now, doesn’t mean there aren’t things that I can still do to challenge myself.”

Of course. He should have known that there would be nothing that could stop Gai from doing what he wanted, even with a broken leg that would never heal again. It only made sense that he would find new ways to challenge himself, and so long as he wasn’t straining his injured leg Kakashi didn’t care to stop him. After all, that was Gai. Never giving up no matter what obstacles he may face in life.

“One more try,” he offered, smiling when Gai levelled him with a doubtful look. “Just one more, I promise. And then we can go grab something to eat. How does that sound?”

The look that Gai gives him in return is a cross between doubtfulness and pride. An interesting combination, but judging by the fact that Gai was locking his wheels into place and relaxing into his chair he could assume that the deal was made.

Which meant he had one more attempt. One final try to make even the slightest amount of progress. To prove to himself that he wasn’t just wasting his time on this endeavour and that a new powerful Jutsu could be created if he just kept at it a bit longer.

Turning to face the wall he had just created, he took a deep breath and began to focus his chakra into his hands and imagined the wall that he wanted to create. One was made out of a stronger mineral. Something that could handle the abuse rained down on it from an attack striking it constantly.

In his mind, it was a beautiful mixture of purple and green. Jagged and sharp to touch and solid.

A Jutsu that could protect his village. That would keep all of his friends safe, no matter what attack it had to hold off. So that he never had to see someone he cared about die again or…

His eyes darted back towards Gai, lingering on his leg for a moment.

A Jutsu to protect his precious people.

“One more try,” he reminded himself, focusing his attention back on the training field and digging his heels into the ground. “You can do this, Kakashi.”

Gai, Naruto, Sakura, Tenzo, Sai, Sasuke. The list of people he wanted to protect was endless, and while some of them could do the job infinitely better than him he still wanted to try. What good would he be as Hokage if he couldn’t even protect his precious people?

The hand signs were easy enough to weave. Already cemented in his memory from the multiple tries he had made before this. In the blink of an eye, he had finished weaving the signs and slammed his hands down against the ground, his eyes glued on the space in front of him as a giant wall rose from the ground to protect him from an imaginary foe.

It was mud. Still, just mud.

“Damn it.”

“It looks stronger than before,” hearing Gai’s voice getting closer to him, Kakashi turned his head to the side and watched as his best friend wheeled up to his side. “Your hard work is paying off, Rival!”

It was amazing how Gai could look at anything and see success. Even with the biggest failures, he could find something to celebrate. The smallest bit of success to focus on, while Kakashi dwelled on the failure.

“It’s just mud,” resting a hand on his hip, he glared at the wall in front of him. “Nothing has changed.”

“Sometimes looking at the bigger picture makes you miss the small victories,” Rolling further ahead, Gai stopped directly in front of the wall and reached out to tap his finger against a small portion of the wall. A spot where, if he focused hard enough, Kakashi could see the smallest glimmer of purple. “It may not be much, but it is an improvement. Don’t you agree?”

Waiting for Gai to lower his hand, Kakashi slowly reached out to touch the wall. Almost not believing what his eyes were seeing, he expected to feel the mud. brittle and flimsy, but effective for a short period. What he felt instead was a solid rock-hard surface. Not jagged, but stronger than mud could ever hope to be. “Since when are you the insightful type?”

“Well, someone has to pick up the slack when you’re too busy being down on yourself,” giving his head a shake, Kakashi dropped his hand back down to his side and turned to face Gai. “Ready to grab something to eat now?”

“That sounds amazing,” He could continue his training in the morning after a nice long rest. For now, he could enjoy some downtime with his best friend. “on one condition.”

“Kakashi…”

“No, hear me out,” Gai would probably think he had lost his mind, but it was worth a shot. “We should have an eating competition.”

Gai’s jaw dropped open. “Did you just-“

“Don’t tell me you’re not up for it,” doing a one hundred eighty-degree turn, Kakashi gave Gai a playful wave. “Come on. I bet I can beat you no problem.”

His teasing was met with a triumphant shout. One that could easily shatter the windows in a building, if they were close enough to one. “I’ll win this challenge Rival, don’t doubt it!” He proclaimed with the same pride and enthusiasm that he always had when it came to their challenges. “And once I do I’ll be ahead of you in points once again!”

“We’ll be tied,” Kakashi corrected him as he started to make his way towards the exit. “You keep forgetting about the Sushi eating competition!”

“This will be a rematch of that then! And I’ll prove to you once and for all that I can beat you in anything!” The sound of Gai’s wheelchair moving behind him brought a smile to Kakashi’s face. One that he could only explain with a single word. Relief.

Relief that he hadn’t had to say goodbye to another friend.

That he didn’t have another name to look at in the memorial stone.

For that, he would gladly have another hundred challenges without complaint.

“I will win,” Gai’s voice called out to him. A blinding smile greeting him when he looked over at his friend. “I can promise you that, Rival.”

“Well, If you do then I’ll just have to spend the whole night working on my Jutsu,” He decided, chuckling when Gai’s eyes went wide. The use of his impossible punishments not going over his head, even when they came from Kakashi’s mouth. “After all, I can’t let you beat me at everything.”

Prompt Discussion - Jutsu Creation

Your only limit to interpreting our prompts is your own  imagination! However, it was suggested to us that some talk about our  prompts might prove helpful, or just fun, and that’s what this little  series is about!

Feel free to comment, engage with, build off, or completely ignore these posts as you like best.

Jutsu Creation (September 12th - Day 1, Prompt 1)

We know Kakashi started creating jutsu early - what is perhaps his signature jutsu (so much as the ninja of a thousand jutsu can have such a thing), the chidori, was created when he was still a child - if an active duty ninja child.

🍃 How did Kakashi come to create chidori? Was it the first jutsu he created? 🍃 Minato certainly created many jutsu himself - did he teach Kakashi to do so? Or was he surprised (and impressed) when he found out? Worried? 🍃 Has Kakashi taught any of his students how to create jutsu, or only to use existing ones? 🍃 Has Kakashi ever come up with a brand-new jutsu in a tight spot in battle? 🍃 Are any of the jutsu Kakashi has created for recreational purposes or just for fun? How did he come to create those, if so?

Jutsu form a wide and fascinating array, even more so if one wanders off the path to create one’s own! What will you highlight?

What kind of instrument would be suitable for a sound-based Genjutsu user? I've been thinking a lot, but I keep coming back to flutes due to practical reasons (size, material, weather influence, etc), but giving my OC a flute would just feel like a Tayuya ripoff somehow. Do you have any instrument suggestions or what to keep an eye on when creating a sound-based user?

This is a novel thought but: if you don’t mind the lack of visual appeal and like the cloud of confusion, you can consider percussion instruments.

Hand-drums, for example, are small and lightweight - easy to carry and use. Rhythms are famous for being able to trigger a psychological reaction in humans IRL, so if your genjutsu amplifies the rhythms / sounds, it’s just as viable a weapon as a flute.

Or a wooden fish, or a those scraping instruments, or those rice-in-a-shake-bottle or impromptu improvised instruments to throw your opponent off guard because they don’t know what to expect, or just their voice, or whistling… etc etc etc

Don’t limit yourself by only thinking of melodic instruments when it comes to some utilitarian as ‘what am I going to turn into a weapon’ think about the function of the technique, then backtrack to the various ways it can be created, then consider what are the objects that can create those things.

Cheers! As an instrumentalist I am overjoyed someone is showing interest in crafting sound-based techniques!

I'm planning out a Shino-twin-sister OC, and I was wondering how tied to his elemental affinities I need to be? I want her to use Wind Chakra for weapons (kama and kusarigama). Should I start with Fire/Earth, or would starting with Wind be okay? Or could she skip training her affinity and work first on Wind?

Woah, stop right there.

If you have an end goal in mind, either go towards that or change it, no half-hearting the journey.

You want her to have wind-based taijutsu tricks? make her have a wind affinity. doesn’t matter if it’s rare. It exists, you want it done, bam it will be done. simply make a note: no one in the Aburame clan has had wind chakra in generations, something like that.

Never write someone that skips training their strengths to focus on a mere want. The thought process of your character should be: i have x affinity, and y weapon works well with that. I’ll go with y weapon as my main and pour my time into x and y!

Never: I want to use y weapon. x affinity goes well with y weapon and I can use it, but z is my actual affinity. because I want to use y weapon, I will train x instead of z because I want to.

It’s illogical and a waste of energy. Stick to what you’ve planned. it’s not a mary-sue if you have proper justification and context, don’t worry.

For my main clan's (of my fanfic) doujutsu, I want to keep the Justus of it to be all electricity based. Would having something where electricity is charged into one hand, a foot, limb, or a weak charge over the entire body be too OP or too similar to the chidori? I was planning on that specific jutsu in their family to be more taijustsu based as well since it needs contact to harm the opponent.

Er, you need to sort out terminology. ‘Dōjutsu’ specifically refers to eye techniques that are exclusively kekkei genkai like the Sharingan, Rinnegan, and Byakugan.

Electricity-based techniques are classified under the Lightning nature transformation.

If you use the canon terminology to sort out your thought process it’ll make the content clearer and more in context and easier to make a decision.

As for the technique you proposed in question, no it’s not OP if you justify it correctly. A human child cannot effectively shock a powerful shinobi adult to death because a) child’s chakra is likely not enough and b) powerful shinobi adult likely can weather such an attack from a child. But a jōnin who’s planned their move carefully can potentially deliver a fatal shock to a similarly-leveled opponent who is caught off-guard.

Also, electricity does not work the way you might’ve thought it’d work, but that might just be me nitpicking your sentence structure. Still, if you were to pump say a 1V charge into a finger, that volt would travel from my fingertip to all over my body, because that’s how electricity works - it gets conducted where there’s a conduit. You can pick and chose where the volt is applied, but it would not change the end result of a whole-body shock. Thus, the only variable left is the intensity and power of the shock in question.

I’d say, with some restrictions and the execution more cleared up, the technique you described is perfectly viable.

It’s not similar to the chidori at all, don’t worry. The chidori is when a user gathers such a concentration of lightning-based chakra outside their body that the chakra becomes visible by the naked eye and gives off a loud, chirping sound.

If you make your clan have a special super affinity towards and potency of lightning-based chakra, they do not need to gather so much chakra outside themselves to the create the same effect as the chidori. and anyway, if they’re going to be taijutsu-focused, the technique should NOT take so long a time as a chidori to form.

Contact - definitely. but indirect contact too, i hope, through a conduct should also be equally devastating.

good luck!

What do you think of a shapeshifter kekkai genkai? Is it kinda useless considering genjutsu?

If a shapeshifitng technique’s rendered useless, it’ll not be genjutsu. If you’d like feedback on that line of reasoning, feel free to send in another ask!

Mainly, you have to consider the basics of your kekkei genkai, its limitations, weaknesses, and strengths. Is it because the form they take on is more powerful than a human, and if that’s the case, what exactly can animal forms improve on the human physique? Speed, strength, dexterity?

What is the use of the kekkei genkai, for stealth, or for direct confrontation, and is the shape one shifts into pre-determined, or fluid, and if so, how is it determined?

Perhaps you’ve answered all those questions, in which case I’ll give a piece of advice: don’t make the clan into a circus carnival.

Also consider why did the clan survive for however long they did, given the existence of summoning animals and their summoning masters, who can dedicate their entire lives to the training and mastery of one form instead of two, and work as a team in a 2 vs 1 situation against your shapeshifting clan.

From what i’ve written so far, I have doubts to the survival of the clan, as nothing they have is special, and can in fact be replicated to increased efficiency. Case study: Inuzuka.

One more point to consider: what is the nature transformation of your kekkei genkai? I have no idea.

Hi ! How hard is it from a ninja's point of view to create a new technique ? What would he have to do ? Choose the appropriate handseals (if it's a nature transfor;ation) and experiement endlessly ?

I can’t remember actually seeing the method of someone creating a brand new technique in canon. Naruto creating rasenshuriken would be a good place to look, though he had the rasengan as a basis to work off of. It took Minato 3 years to create rasengan, so if you want to create a high level techique remember that it will take a while to do.

Hand seals are not actually required to use a technique (eg Sasuke and chidori), but I am under the impression that there is some kind of meaning and logic behind hand seals. The wiki shows which hand seals are commonly associated with particular nature transformations and jutsu.

I imagine creating a new jutsu is kind of like creating new science, and these are the steps I came up with. It is by no means a definitive guide but should hopefully give you some ideas.

First off, the ninja should have a good understanding of existing techniques of the same nature transformation (where applicable) and type of jutsu to the one that they intend to create. Then, they should break their technique down into as many smaller steps as possible (think of how Naruto learnt rasengan) and once they are proficient in all these steps combine them in a logical order to create their jutsu. The main problems will be in ‘troubleshooting’ their jutsu and balancing the different steps. There will also be cases where the ninja has to go ‘back to the drawing board’ and try different steps if the ones they came up with don’t work. Like Kakashi and chidori, there may also be problems with practically using the jutsu even if it works outside of battle, which will have to be overcome.
