Kakashi unlocked his chakra,
"I can finally start my ninjutsu training."
"Hold on Kakashi, we still have to determine your chakra affinity."
Sakumo removed a piece of paper.
"Kakashi, hold this paper."
Kakashi placed his finger on the paper, and the whole paper wrinkled.
"Lightning, good job Kakashi."
Sakumo smiled, then looked at Ryuu.
"Ryuu, are you ready?" Ryuu nodded and smiled. He couldn't hold his excitement in.
Neither could the clan heads.
They were eager to see what Chakra affinity the Genius of the leaf got.
Ryuu didn't want to show too much of his chakra, so he decided he would try to suppress some of it.
"Ryuu, do exactly what the scroll told you to do and I will help guide you, ok?"
Ryuu nodded back and then closed his eyes.
'Sakumo released some chakra into me. My body tried resisting, but I couldn't allow that, so I calmed down my nerves and let his chakra ignite my dormant chakra.
When they were finally about to contact, my chakra lashed out wildly and suddenly I felt a great surge of power it spread and flow through my veins and made me open my eyes.
This chakra was so immense that it became visible to the naked eye, I tried to hold it back as much as I could then,'
"Boom!" a massive Shockwave hit the ground, and it left with many cracks and dents. Even Sakumo had to jump back.
Everyone on the training ground became shocked because of what they had seen. Everyone's jaws were on the floor, even Fugaku, and he always had the same expression on his face.
Kakashi was so shocked he got lost. In his thoughts,
'Ryuu has surpassed me in chakra by Lightyears.' He thought to himself.
'So this is your child, Hanzo?'
Fugaku thought to himself.
After many minutes of silence, Sakumo finally spoke.
"Very well then, Ryuu, place your finger on this paper, and let's see your chakra nature."
Ryuu took the paper and infused some chakra into it.
A portion of the paper caught fire and turned into Ash, then half of the paper split into half, one side wrinkled, and some part of it then turned into dirt, and finally, the last part became damp.
"Impossible!" Lord Third couldn't believe it.
"Ryuu's chakra affinity is all the elements." Everyone was shocked by what they had witnessed on the training grounds today.
Lord third called an Anbu member and whispered something into his ear.
"Congratulations Ryuu and Kakashi, you've unlocked your chakra and now you can start learning ninjutsu and more.
As a token of my goodwill, I will hand over these two Jutsu's, open them while you're at home."
The Anbu that Lord third had sent away came back with two scrolls and handed them to Sakumo.
"Whoosh!" out of nowhere, Fugaku suddenly appeared in front of Ryuu,
"I expect to see you in the Uchiha Grounds in a week.
Your father can escort you to my house, but I don't expect to see anyone else after that."
Fugaku said as kindly as he could.
Ryuu looked at Kakashi, and before he could speak, Kakashi nodded.
After the ceremony was over, Sakumo left the Hokage Estate with Ryuu and Kakashi.
"Today I will treat you to some barbecue to celebrate both of you unlocking your chakra."
Ryuu and Kakashi looked at each other with excitement.
They went to a restaurant somewhere nearby. After eating and chatting for nearly 2 hours, Sakumo and his children went back home.
They soon reached home, but Ryuu was stuck behind.
'Wait a second, I can get some leaves for my chakra control training, I'll grab some leaves, some for Kakashi and some for myself.'
After grabbing a bunch of leaves, Ryuu went inside. He pretended he was sleepy and exhausted and went to his room immediately.
Kakashi found this suspicious cause Ryuu never gets tired so easily, so he followed him and snuck into his room.
Meanwhile, Ryuu had just closed his door, he sat down on the floor with his legs crossed and took a bunch of leaves from his pocket.
He then took one from the bunch and placed it on his forehead and focused some of his chakra to balance the leaf and prevent it from falling.
Kakashi snuck in through Ryuus' window and said,
"So, this is what you're hiding?"
Kakashi interrupted Ryuu and dropped his leaves.
"Hey what did you do that for?"
Ryuu asked as he pointed at Kakashi.
"I wasn't hiding anything. I expected you to come. That's why I grabbed some leaves for you, too."
In the morning, Ryuu was the first to wake up and woke up Kakashi.
"Kakashi, Kakashi wake up. We're gonna learn ninjutsu today to get up.
Stop pretending I'm not here. I know you well enough to tell, let's go wake up, dad."
Kakashi finally got up.
Yawn
"Sometimes I wish I could just sleep in peace without you or dad waking me up to go train," Kakashi said as he stretched.
The two of them went to wake Sakumo up, they entered his room stealthily and tried to wake him up as peacefully as possible.
"Dad, wake up, you said you'll teach us ninjutsu today."
They tried to shake him up, but there wasn't any difference. Suddenly Ryuu had an idea and smirked.
Kakashi knew all too well what that smirk means.
"I hate it when you do that smirk. Nothing good comes from it."
Ryuu looked at Kakashi and pulled him closer. He whispered something in his ear and Kakashi's eyes were widening in shock the more he heard this plan.
"Ryuu, no, we can't do this Ryuu. That plan will get both of us kicked out of the house."
Kakashi refused to take part in Ryuus' plan,
"Come on, Kakashi, if we don't do this, then we won't learn any ninjutsu.
We have to take some risks."
Ryuu pleaded and put his knees on the floor while looking directly at Kakashi with his hidden technique "Sorrow eyes Jutsu."
Sigh
"Fine, as long as you stop doing those ridiculous eyes."
Kakashi rolled his eyes and agreed.
Ryuu started smiling again and jumped with joy.
"Thank you, Kakashi."
Kakashi didn't respond because he just wanted to finish as quickly as possible.
"Ready?" Ryuu asked Kakashi, who was squatting and putting both his hands together. He nodded.
Ryuu ran and gathered some speed, then he used Kakashi's hands as a boost to make him gain some height, and then "Boom!" Ryuu landed on Sakumos stomach.
He woke up and clenched his stomach for dear life.
*Poof*
Sakumo suddenly turned into a small cloud of smoke. "Huh, a Shadow clone. Then where is dad?"
A voice came from behind the two and said.
"Clone jutsu is a key jutsu that will be what the academy will use to decide if you should graduate." Sakumo Said as he appeared out of nowhere, "Ah!" Kakashi and Ryuu both yelled in shock and fear they felt as if their souls had left their bodies.
"Don't you think it's a little too early to be scaring the life out of your sons?"
Ryuu asked as he was catching his breath.
"No, not really, but don't you think it's a little too early to be breaking your old man's fragile bones,"
"Fine, you have me beat today,"
Ryuu mumbled to himself.
"Anyway, today both of you will start training your chakra with a simple leaf exercise."
"Ha, we're already miles ahead of you, Dad.
Kakashi and I spent all night training our chakra."
Ryuu said as he went into his room and grabbed a bunch of leaves and placed 4 on his forehead and balanced them. Kakashi took three leaves and placed them on his forehead and balanced them perfectly.
Sakumo was so shocked and proud to see his kids master the technique.
"Well, that makes things much easier for me. Well, I'll teach you ninjutsu now."
Sakumo removed two scrolls from his pocket.
"Wait, those are the scrolls that Sarutobi-sensei gave us?" Ryuu asked as he and Kakashi gazed at them in awe.
"Yes, Hokage-sama was very generous in handing you two of these A-rank Jutsu's, this means that he believes in your potential.
I have to admit I thought it was too much for you guys, but seeing you two master the leaf concentration technique overnight has made me realize how greatly I underestimated your abilities, anyway, I need you guys to master these Jutsu's."
He pulled out two scrolls and gave them to Ryuu and Kakashi.
"In those scrolls, I've put two Jutsu's for both of you. After you master them, we will start working on your A rank. jutsu, with that being said, let's get started."
