Chapter Text
Sukuna knew today was the day he started his training arc. He would have to do a lot. After all, he was born in the pathetic Haruno cla- family. They were too disgraceful to be called a clan. He was about to go when...
Sakura sees Sukuna leaving and asks, "Where are you going, Onii-chan?
Sukuna answers by saying, "I'm going to train, Sakura."
Sakura questions, "Why not just wait until we enter the academy?"
Sukuna answers, "I want to become the strongest in history. I need to start now if I want to reach my goal."
Sukuna then walks out. He didn't really care what his family thought about him. He goes to the library and meets Uraume. He seems to be reading a green book about wind releas
"Uraume, what are you reading?" Sukuna asks.
Uraume responds, "I am reading a book about wind release to help you. I believe if you refine the justsuWind Release: Dissect,Wind Release: Slash,andWind Release: Airblade Assaultto create your dismantle jutsu."
Sukuna reads the jutsu from the book and agrees with her.
"These jutsu is the most fitting for dismantle." Sukuna agrees.
Wind Release: Dissectis a C rank jutsu that releases wind blades in a graph shape at the opponent, slashing them into multiple pieces. This jutsu relies on the amount of chakra put into it.
Wind Release: Slashis a D rank jutsu that releases a singular slash at the opponent, cutting them. This jutsu relies on the amount of chakra put into it.
Wind Release: Airblade Assaultis a D rank jutsu that releases a barrage of slashes with no pattern at your opponent. This jutsu relies on the amount of chakra put into it.
Uraume tells Sukuna, "The only problem with the jutsu is that their too easy to see and counter."
Sukuna shows his gratitude towards Uraume by saying, "Thank you for insight, Uraume. I'll rent this book so I can do more studying. I recommend you pick up some books on water release."
Uraume responds, "You're welcome, Sukuna."
-Timeskip: Training field-
It was time for training. They went to a nearby training ground. It took a while, but they found a tall 70 foot tree next to a river.
Sukuna says, "This is the perfect place for training."
Sukuna then took of his shirt
Uraume becomes a blushing mess. He covers his eyes but is clearly looking through his fingers.
Uraume, blushing says, "S-Sukuna?! W-What are u doing?!"
Sukuna responds, "I taking off my shirt. I don't want it to get sweaty."
Uraume, still blushing, says, "O-Ok Sukuna."
They quickly get to training. Sukuna was a prodigy. On his 1st day, he was already able to climb the tree. One the 2nd day, he almost mastered the water walking technique. He decided to help Uraume. He didn't want him to fall far behind. With Sukuna's help, Uraume quickly mastered tree walking and water walking. This took 3 days. They then moved onto kunai balancing. While the other exercises needed you to focus chakra on their entire foot, kunai balancing requires you to channel chakra on a single point to perfectly balance the kunai with still and calm chakra. Uraume had an easier time completing this one. Uraume's chakra was far calmer than Sukuna's. This took another day, so they've been training for 7 days.
Sukuna explains, "Now that we have done all of the exercises, I want to work on our ninjutsu. I will learn the 3 jutsu you recommended. I want you to learn about air and water release and how to combine them into ice release. Maybe you can ask your mother if you need help."
Uraume responds, "I understand, Sukuna."
-Timeskip: 3 weeks-
Sukuna and Uraume mastered their respective abilities. Sukuna has made dismantle and Uraume has made frost calm, however, they take quite the bit of chakra. They haven't fully mastered their abilities, yet.
Sukuna states, "Now that we have created our respective abilities, I think that we should work on taijutsu. I retrieved some books on taijutsu on many different taijutsu styles to create our own."
Uraume agrees, "I agree, Sukuna. We can't just rely on ninjutsu."
They were about to go back to training, but Sukuna heard a wooshing noise from behind Uraume. He quickly grabbed him and tried to dodge, but he was hit in the Achilles tendon.
Sukuna winces in pain. Uraume catches him and holds him up.
A mysterious voice says, "Well, well, well. This is what you were up to Uraume? We haven't seen you in a while."
It was 2 boys and 2 girls. The 2 girls were ninjas. The boys were slightly older than us and the 2 girls were significantly older than us and the boys. The 1 dot on their headbands signifies their genin status. I don't know if Uraume and I will be able to win this, especially with my injured leg.
Boy 1 exclaims, "Hey Ura-Bitch. You really thought we would let you get away?"
Boy 2 says, "Why don't you go back from where you came from?"
Sukuna co*ckily exclaims, "Seriously? A 4 vs 2? Pathetic. We'll fight you all and win."
Uraume: Are you sure?!
Sukuna: If they all jumped us at once, it might cause me a little trouble.
Uraume: But would you lose?
Sukuna says,
𝙉𝙖𝙝, 𝙄'𝙙 𝙒𝙞𝙣
Sukuna quickly points his hand on them and says,
"Dismantle"
Sukuna sends a barrage of slashes at them. The 2 girls cover the boys, taking the hit for them. Their bodies have tons of cuts at them. Both girls and boys disappear, leaving some blood on the ground.
Sukuna, surprised, thinks, "Genjutsu?! I still got them a little since there's blood on the ground. They must've only activated the genjutsu at the last second."
Sukuna senses the girls' chakra running towards them, turning his head around and sending anotherdismantleat them. They were far faster than the last ones. These slashes targeted their legs. He sliced their knees and shins on their legs. He has lost about 1/4 of his chakra. The 2 boys then run for their sisters.
Sukuna exclaims, "Now Uraume!!!"
Uraume activates his jutsu,"Ice Formation: Frost Calm"
Uraume sends a cold mist at the squad. When it hits them, ice quickly forms around them freezing them in place.
Sukuna, now calm, says, "Kill them, Uraume."
Uraume grows an ice spike on his finger and points it at Boy 2. As he was about to stab the bastard, one of the girls used chakra to strengthen their bodies, breaking the ice. Uraume jumps back to Sukuna. The other girl fights through the pain, standing up and launchingWater Style: Slicing Exorcismat the couple.
(A/N: Imagine its water, not blood)
Sukuna angrily yells, "sh*t!!!DISMANTLE"
Sukuna sends 1 singular, powerful slash at the attack. This attack slices throughWater Style: Exorcismand slices the 2 girls on their chests. It isn't deep enough to be lethal, but it's definitely painful. Suddenly, 3 Chunin appear.
Chunin 2 ragefully yells, "WHAT THE HELL IS HAPPENING HERE?!"
Sukuna calmly says, "Those 4 attacked us. They said that Uraume *points at Uraume* should go back where he belongs. He is a refugee from Kiri."
Boy 1 co*ckily says, "Yeah he should. His kind... DOESN'T BELONG HERE!!!"
Chunin 3 says, "You are all being detained."
Chunin 1 uses a powerful genjutsu, knocking the 6 children out.
-Timeskip: 3 months-
Those 4 retards who attacked Sukuna and Uraume were put on house arrest for 7 days, since they were young. The 2 genin also had their ninja licenses suspended for 6 months. Sucks for them. They're going to miss this year's chunin exam for sure. The nurses in the hospital helped them recover. Due to some of them knowing medical ninjutsu andChakra Regeneration Technique,the medics healed the 6 of them in 1 day. Sukuna and Uraume instantly went back to training, evolving their taijutsu and ninjutsu for 2 months. They focusing on their ninjutsu and genjutsu in the 3rd month. Uraume was able to evolve frost calm to a level he was happy with. Sukuna was able to refine dismantle, increasing his reserves. He was able to make his slashes straighter, sharper, and stronger. He also developed a very weak cleave. He does cleave by planting a chakra storage seal, filling it with wind chakra, and then disrupting the seal using a 1 handed ran sign, slicing his opponents from the inside. He learned enough about seals and refined his calligraphy enough to get chakra storage seals on his wrists.
(A/N: They are on both hands like in canon.)
They looked like just regular tattoos with no purpose but if you zoomed in enough, your would see complex symbols made with special chakra ink. He was going to get the rest of the tattoos as he got older. The seals he has slowly take chakra from his chakra system, forcing his body to expand his reserves. He's working his chakra system like a muscle so he can increase his reserves over time. If he adds all of them now, they will take his chakra faster than he can regenerate it. As the rate Sukuna's going, he should be able to put the tatoos on the rest of his body. Also, after Sukuna fought those bullies with Uraume, all of Uraume's bullies left him alone. He started calling Sukuna "Sukuna-sama" as gratitude. He didn't stop no matter how many times Sukuna asked him to. It's a canon event I guess. Their bodies have become stronger. Sukuna's is still stronger though. Uraume has also made a genjutsu calledGlacial Grove. This genjutsu creates a cold environment. It also stimulates any victim's nervous system, tricking their body into believing they're in a real cold environment.
(A/N: Ignore Itadori and Mahito)
A/N: Alright. I'll stop yapping like Kenjaku. I just want to say 1 last thing. I plan to have all 3 versions of Sukuna in this fanfic I finish it. Bye Bye 👋🏿.
