Iwa's Weapon

Tsuchi no kuni. A barren land, filled with monstrous mountains and vast valleys. It truly is a remarkable country. One of its greatest feats, is housing one of the five greatest ninja villages. Iwagakure. Quite a lively community. Houses built together with brick and stone with mountains surrounding the village on all sides. There was one building however that towered over the rest. It wasn't the academy, or even the hospital. But a tall building, with the kanji for earth displaying in front of a brown circle. It was the Tsuchikage's building.

Inside the main office, was a short, old man, standing at about 4'3. It was Ōnoki, the Sandaime Tsuchikage. The longest kage to reign, joint first with the Sandaime Hokage, Sarutobi Hiruzen. However, Ōnoki was very dissimilar to Hiruzen. Ōnoki was not pacifistic. Some may say he enjoyed war time. That all changed during the Third Shinobi World War. He began to see the benefits of peace after he had to bury his only two children. This left his granddaughter, Kurotsuchi, with no mother, relying on Kitsuchi, her father to look after her. That was six years ago.


"Nii-san!" shouted a young blonde haired child. The boy had violet pupils that while friendly, seemed to stare deep into the other person. He was wearing a beige cargo shorts, and a plain white t-shirt. He also had a pair of beige civilian sandals. He had two blonde bangs that framed his face. The rest neatly tied in a ponytail. "You're back from your mission!"

"Hai otouto, did your caretaker treat you well?" asked a slighter bigger blond with a ponytail. He was currently taking of his hitai-ate and rested it on a nearby table. He was wearing what appeared to be a blue and grey kimino jacket with a fishnet undershirt. He has khaki pants with sandals, and a belt, which contained a bag full of clay. His blonde hair covered his left eye, giving off a mysterious look.

"Hai, she was great. Now that your home, can you make us something to eat please nii-san?"

"Of course, Sekki."


Around 15 minutes later, the older blonde came walking back into the room carrying a slip of paper and a meal.

"Sekki, I would like to test something quickly. As you know, we unlocked your chakra last year, and we began small workouts 2 years ago, when you were four. I want you to hold this paper. This is known as Chakra Paper, it helps me see what elemental affinity you are going to have."

"But Deidara-nii, I haven't got very good chakra control yet?"

"You don't have to worry Sekki, I will assist you."

"If you insist Nii-san." The young blonde hesitated for a split second, but realised just who was talking to him. His Nii-san. They were born with quite a big age gap, 9 years to be precise. Ever since Sekki could remember, he had never seen his parents or any family apart from Deidara. Sekki was smart for his age, and realised that many families have two people, normally a male and female. So Sekki realised he didn't have parents, but decided not to question his Nii-san. He would always trust his Nii-san.

The paper crinkled, heavily. It startled Sekki, since he is still a young boy. Less than a second after, the paper crumbled to the ground, so small it couldn't be seen by the human eye.

"Yes, YES, YES!" exclaimed Deidara joyously, talking to himself. "He possesses Bakuton. Dear Kami-sama, thank you, you have just created an amazing weapon."

"…Deidara-Nii? …What happened?" asked a young Sekki nervously.

"You possess a kekkai genkai, otouto. The Bakuton to be exact. I also possess it, so I was hoping you would get it from our Tou-san aswell. Eat Sekki, this will help you control your powers."

Deidara proceeded to force open Sekki's mouth, and shove the food into his mouth. Deidara smirked. It wasn't a happy smirk, more of a vicious one. There was another handful of food left on the plate, which Deidara proceeded to force down Sekki's mouth.

"…Nii-san? What was that Nii-san, it tasted like clay? It feels as if it's connecting to my stomach, like it is part of the organ tissue. It hurts Nii-san."

"…It worked. My plan, my experiments, they all worked!" exclaimed the older blond.

"But it hurts Nii-san, why did you feed me it?" gasped Sekki in obvious pain.

"I heard that Iwa possesses a kinjutsu. So I decided to steal the scroll and use it on myself! With my Bakuton bloodline, I can create explosive clay! I'm more powerful than I've ever felt before. I feel like nothing can stop me!"

"…But that's … a crime. You wouldn't leave me here by myself would you?"

"I'll give you the choice. Leave the village with me, your 'Nii-san', or remain weak for the rest of your life."

"But Nii-san, don't you possess the Will of Stone? Because I know I do! I will fight for this village until my last breath!"

"Hmph, for a 6 year old, your quite the smart one aren't you. I guess that is my fault, trying to make you into a weapon by giving you several books about being a ninja." mumbled Deidara to himself, "Sekki, why remain in this foolish village, I can tell in your eyes, all you want is someone to love you, someone to hold and someone to hug. You desire a family! Come. Come with me on my adventure. Watch me blow the Tsuchikage's building. I can teach you the powers I possess, follow me."

"…No. No, I can't. No, my Will of Stone is harder than yours. Your Will of Stone is nothing but a pebble, whereas mine is a diamond. I will fight for this country till I die!" said Sekki.

"…I see. You're going to abandon your family, for the sake of a village. I see. I will take my leave then, later … Otouto."

And just like that he was gone. Deidara disappeared in a small, controlled explosion. However, it was enough to knock Sekki into the wall unconscious. Less than a second later, the older blonde returned and picked up his hitai-ate. Deidara stared at his otouto a bit longer. Wishing he made the right decision. Wishing he said no to Tsuchikage-sama.


While Deidara thought no one had heard the small explosion. There was a young girl walking down the road. She had short black hair, and bright pink eyes that shone in the sun. She was walking with her father, Kitsuchi. She got lots of nods of acknowledgement on her way through the village. Probably what being granddaughter of the Tsuchikage does. For a young girl, she had a good sense of hearing. So when the explosion went off, she turned to stare at her father. Kitsuchi had also heard the noise, and started looking around for any noticeable damage. He saw an apartment, with a window blown out. Upon closer inspection, he realised it wasn't any old apartment. It was Deidara's, a renowned Iwa-nin. Some believed he may be in the running for the position of Yondaime Tsuchikage, but now wasn't the time to worry about that.

Kitsuchi picks up his daughter and performed the Shunshin to get into the apartment. He looked around, and saw a young boy around the same age as his daughter, unconscious.

"Kurotsuchi-chan" said Kitsuchi apprehensively "I'm going to need to take this young boy to hospital."

"Will he be alright tou-san?" asked a young girl, now identified as Kurotsuchi.

"I'm sure he will be, I need you to be brave and go to the Tsuchikage tower, can you do that for me? You'll be safe with your gramps."

"Love you tou-san, I'll go see jiji then."

As soon as Kurotsuchi left, Kitsuchi picked the boy up, and performed the Shunshin to get to the hospital.


"He will be fine sir, there is a minor problem with his brain that made him unconscious, likely from shock or fear. Do you have any recognition of the boy's name for medical records?" asked a doctor.

"His name is Sekki. No surname, just Sekki. I believe he is Deidara-san's younger brother." Replied Kitsuchi.

"That is worrying." Said the doctor "there have been reports of explosions going off near the Tsuchikage tower. There are speculations that Deidara-san may have betrayed Iwagakure."

"Shit. I need to go, I sent my daughter to the tower." As soon as Kitsuchi finished the last word, he was out the window, using chakra to make the landing less painful and ran as fast as he could.


"Oh, would you look here, if it isn't little Kurotsuchi-chan. What are you doing here?" asked Deidara.

"Deidara-Nii! What are you doing blowing up the tower? I thought you loved the village?" asked the pink-eyed girl.

"I lost my love for this place a while ago, I'm here to assassinate your grandad." Deidara replied viciously.

"Don't you dare touch him! Just leave and never come back, don't hurt him!" shouted Kurotsuchi "You obviously don't believe in the Will of Stone anymore, so just leave!"

"Will of Stone this. Will of Stone that. You sound like my otouto. You know, the one I just blew up."

"You did that!? Why, WHY" she cried "He's your family!"

"I do everything I do for power, my otouto is weak, and his ideals are weak. He is too optimistic to be a strong weapon."

"Deidara." A new voice said, it sounded croaky and old, yet held power, that if the speaker wanted, they could kill anyone. "Leave or die."

Deidara glared at the old man. The old blonde took out a kunai, took of his hitai-ate, and slashed at it creating a deep cut going through the metal.

"I will be taking my leave, Tsuchikage-sama" he replied venomously.

"Jiji. Are you ok? He said he wanted to assassinate you." Kurotsuchi asked quietly.

"Did he now? You know how strong your gramps is, everything is under control."

"…Jiji, do you think we can visit the boy at the hospital?" she asked nervously "I want to make sure he is ok."

"Of course Kuro-chan."

With one last look at the direction Deidara went, his mind started thinking.

'That was brave of you Deidara. Too willingly, or unwillingly I guess since the explosions were not part of the plan, agree to make sure his brother has the potential to surpass all of the old Tsuchikage is a miracle. I'll need to thank my scientists. Being able to combine Mū-sensei's DNA and the explosive clay, truly a work of art.'


"Grrhh"

"He seems to have awoken, Tsuchikage-sama."

'What is this, am I waking up. The walls are so bright it's hard to open my eyes.'

"Hello Sekki, I am Ōnoki, the Sandaime Tsuchikage."

"…Huh, oh you? I already know you." Said a tired Sekki, somewhat bored.

"So you know who I am? How?" asked the Tsuchikage.

"I'm six. If I didn't know the Tsuchikage I would question my own intelligence. Besides, Nii… Deidara-san made me read about certain powerful ninja, dead or alive. I can name all Kage apart from a few from Kumo. All their names are 'A' or something so I get confused between their powers." Responded the young blonde.

"My, what knowledge, can you tell me about the Nidaime Mizukage?"

"Jeez, interrogating a six year old. Well he was from the Hōzuki clan, first name Gengetsu. Owner of the Clam summoning contract. Used his Clam's for a sort of mirage effect. Highly skilled. He had a rivalry with our Nidaime Tsuchikage, Mū. They ended up killing each other in a massive fight. Shortly after, you became the Sandaime."

"What great knowledge." Said Ōnoki happily "Any other interesting facts about you I should know?"

"Hmm, I can name a lot of S-class shinobi. Deidara-san made me read the Bingo Book a fair few times. He also made me read about bijū and jinchūriki. I have a common understanding of chakra and chakra control, however I have quite big reserves for someone my age so I can't control them the best. I was hoping to start the academy somewhat soon but hey, I don't really mind."

"Why don't I do you one better, I will personally train you." Replied the Tsuchikage.

After a minute or two of being shocked and understanding the privilege he had just been offered. Sekki asked the most important question in his mind. "Why?"

"Because I see power in you. You possess a strong Will of Stone. As strong as diamond. I will make you powerful enough to protect any future family or friends you may have."

Sekki didn't reply. Simply took his hand out from underneath the bed sheets and asked for a hand-shake, to signify the deal.

"Great, anything else you want to question?" asked the old man.

"Two things. One; why can I sense a girl around my age, if not slightly older outside. Two; why does my stomach feel so, I don't know, so clay-like?" asked a confused Sekki.

"For question one, you may be a Sensor-type ninja. They are rare and quite needed in the modern ninja world. For two, I asked for a report of your body when the doctor told me of you. Your stomach has been infused with clay. Do you happen to know how this could happen?"

"Yes." Replied Sekki "Deidara-san made me eat what he called 'explosive clay'. I guess it's combined with the cells in my stomach tissue."

"It would appear so. I will start your training in three days at precisely 7:00am. It will be at the Tsuchikage tower. Don't be any earlier or later. I will practice your Taijutsu and Ninjutsu. We may even try and experiment with the clay in your stomach. See if we can use it as part of your power to protect."

"I will see you then, Sandaime-sama." The Sandaime Tsuchikage proceeded to walk out of the room, enabling the young girl Sekki sensed to enter.

"Hey there, are you alright? You looked pretty bad when I last saw you." Asked the pretty girl.

"I-I'm fine thanks." Replied Sekki

"Are you nervous? You don't have to be, I don't bite. Hahaha"

This made Sekki blush. He found her laugh adorable. "I have n-never had any friends. So I s-struggle to talk to people who are similar to my age. W-what is your name?"

"I'm Kurotsuchi. And I'm seven. What about you?" This caused Sekki to blush even more because he found her name to be very cute.

"I'm S-Sekki, I'm six."

"Are you going to the academy? We can be friends!"

"I would like to be friends, however ... I am not going to the a-academy." Replied Sekki with a frown. "Apparently the Sandaime has shown an interest in teaching me a few things. I don't know for how long but I may end up seeing you in the academy."

"… Jiji is training someone." Stated a stupefied Kurotsuchi.

"Hai, he is. I am about to leave the hospital. Would you like me to walk you home?"

"I would love it! You are very kind Sekki."

"I- Well- Thank you." Said a very blushing Sekki.

"We need to work on your people skills though, haha."

The pair walked out the hospital, onto the streets and towards Kurotsuchi's residency. They walked out laughing, the first time Sekki has ever shown his nervous side to anyone but his brother.


It was 6:59 when Sekki arrived at the Tsuchikage tower. Outside waiting for him was Ōnoki.

"Good morning Sekki. From now on, you will refer to me as either Ōnoki-sensei or Ōnoki-sama. I will lead you to the training ground where we can begin."

"Hai, Ōnoki-sensei."

After a somewhat quick walk, the two were at a gate. After the gate was unlocked Ōnoki turned to Sekki. "Right, 50 laps around the field."

"Hai, Ōnoki-sensei."

It took an hour before Sekki was finished. "What now Ōnoki-sensei?"

"You don't want a rest?"

"I would prefer if I could not. I need to get stronger to become useful for Iwakagure."

"Fine, 150 press ups and sit ups, I want them completed in under an hour, then I will begin our taijutsu practice."

An hour came and went, and Sekki was feeling like shit. He wouldn't admit it to Ōnoki however, because he didn't want to be seen as week. As soon as Sekki's 15 minute rest was over, he got thrown a scroll by Ōnoki. "This is a basic taijutsu form. It is know as the Stone Fist. A simple style that involves being physically stronger than your opponent. We will learn this style for the 2 weeks give or take a few days. If i think you have mastered it, we will move on sooner. Read the scroll, then copy the stances I perform."

A few hours later and it was lunch. Sekki arrived back at the training ground 30 minutes later.

"We will now be learning chakra control Sekki, I assume you know the mountain climbing exercise?" seeing a nod he continued "Then let us do the water walking exercise."

Sekki proceeded to take off his shirt and do the exercise. It was hard for Sekki, but after two hours he got it down. He remained doing the exercise for another hour, to further increase his chakra reserves.

"Sekki, we have two things I'd like to try before we finish for the day. First I would like you to meditate. You may not enjoy it, however I believe that it will further expand your reserves. Chakra is a combination of spiritual and physical energy therefore with meditation, your chakra will become stronger and you will gain more control over it. After an hour of meditation, we will try to make use of the clay in your stomach."

It was a long hour for Sekki but before long, it was over. "Sekki, I want you to try and feel inside your stomach. Channel chakra inside your stomach. Put it to the lining of your stomach and try to peel off the clay. Once your have a certain amount, I want you to mould the clay. I read the kinjutsu scroll before Deidara took it. It stated that the user would have the ability to mould the clay into whatever shape your imagination thinks of. The scroll recommends insects or animals, once moulded, spit it out. Hold up a half ram sign and it will increase the moulded figures size. Afterwards shout katsu while keeping the half ram sign and it will explode."

Sekki concentrated. He just needed to mould the chakra, coincidentally earth chakra. He succeeded. He could feel a few tiny clay bees inside his stomach. He exhaled, using more chakra to force the clay figures out of his body. He spat them out. There was only three tiny bees, however for a first try, Ōnoki was very impressed. "Try and increase their size."

So Sekki did just that, he performed a half ram seal. The tiny bees, became more of an average size bee. The only thing left to do was to try and explode them. "Katsu"

The bees crumbled to the ground with no sign of an explosion. Sekki scowled. He thought he did it right, now Ōnoki would be disappointed in him.

"That is an outstanding first attempt Sekki" said a smiling Tsuchikage "May I ask why bees though?"

"The Shodaime Tsuchikage was renowned for his bee-related jutsu."

"Interesting, very interesting. We can call it a day or keep practicing."

"I would like to keep practicing Ōnoki-sensei."

"For today, keep practicing your clay related jutsu, and your work with bakuton. After, we will work on breaking down the bakuton, into dōton and raiton. I plan on making your dōton jutsu just as strong as mine."

And so the training went on for two weeks. Sekki would train till exhaustion everyday but he could tell he was getting very strong. He just so happened to meet Kurotsuchi on his way home from a training session.


"Is that you Sekki?" asked a curious voice, but Sekki had heard it before.

"Hey K-Kurotsuchi-san."

"Please dont call me 'san' it makes me feel really old."

"Hai. If you say so."

"So how is training going with jiji?"

"It is going very well, I have just finished learning the Stone Fist to a suitable level. Ōnoki-sensei also has me practicing my chakra control and elemental chakra. I am also meditating to control my emotions and further establish my sensory ability."

"Sounds like jiji is a slave-driver." replied Kurotsuchi while laughing.

"Yes, a bit, but he sure knows his stuff. I can feel myself becoming stronger for Iwagakure."

"Hmph, if you think I'm not gonna train and let you become stronger then your wrong. I just started the academy, and while it may not be hard, I will pass it with flying colours very soon!"

"I wish you luck then Kurotsuchi." After the brief conversation, they both started to walk away, well more hobble for Sekki. However unaware to both of them, Ōnoki was watching the conversation.

'It appears that Sekki is acquainted with Kuro-chan. Maybe I could use this as motivation to make Kuro-chan train harder. I could even invite her to some of the training sessions.'


It was the next day, another training session for Sekki.

"Sekki. Do the warm up, however add another 25 laps and 50 extra push ups and sit ups. Afterwards, I will teach you a new jutsu or two that coincide with the Stone Fist. Get moving."

"Alright Sekki. Read this scroll. It contains Doton: Fist Rock Jutsu and Rock Armour. The Doton: Fist Rock Jutsu needs 6 hand signs. It encases your arm in rock. It acts as an offensive and defensive technique. The positives are being able to strike with higher power and defend against attacks such as projectiles. The negatives however, are that your speed is reduced significantly. The Rock Armour technique requires no hand signs if the user has good enough chakra control, which you do. Channel earth chakra around your skin, and it hardens it. It is an offensive and defensive jutsu. The positives are the same as the Doton: Fist Rock Jutsu as well as once the jutsu is activated, no extra chakra is required unless you want to strengthen the armour. There are no negatives, apart from the armour being useless against Raiton jutsu. You have as many days as you need too learn them. We will still perform our meditation from 4pm - 5pm before dinner."

After watching Sekki try and perform the jutsu, Ōnoki came to one conclusion. That Sekki was a prodigy of the highest level.


So, that is the first chapter. This is my first time writing so I'm kind of nervous. This will be an OC/Kurotsuchi story. I know I haven't made it clear yet, but Sekki is a year younger than Naruto and the rest of the Konoha 12. Their will likely be a small time skip in the next chapter. Not too sure, depends how I feel when I get around to writing.

I do not own Naruto.

Published Chapter 1 - 13/11/2022
