Ninja Academy

The day before Hiroki kept practicing for the entirety of the day and made a lot of progress. After he felt that he had a good control of his chakra, he remembered the hand seals of [water style: raging waves jutsu]. It was a basic water jutsu that was easy to control and the size of it was controlled by the amount of chakra used in it. Hiroki face a tree that was a little distant from where he trained and performed the jutsu. The output of chakra in the jutsu wasn't big, but it was enough to damage the tree to some degree.

"Hehehe. I can't believe I did it. What more could I be able to do from the ones I remember?" Hiroki said to himself in total bliss.

He then tried one of his favorites jutsu:[shadow clone]. He loved how it could be used in many ways and how it helped in training.

A clone then appeared on his side. Everything looked exactly. His eyes, hair, clothes, everything. He then dispelled the clone.

"I better get to the orphanage. I need to rest. Tomorrow is going to be a big day.

Next morning, Hiroki got up early and prepared to go to the academy. As he got near the gate, he saw Minato and Kushina waiting for him.

"Good morning Hiroki. Ready for your first day?" Kushina asked and Hiroki nodded with a smile.

"Why are you guys here?" Hiroki asked.

"We came to see you in your first day in the academy. Any trouble you find in the academy regarding your learning, you can come to us and we'll help you. And don't forget to behave yourself." Minato said.

"Thank you. I'll behave properly."

"Don't let us stop you or your going to be late on your first day." Kushina said as she giggled.

Hiroki then ran inside the academy.

Hiroki was now standing at the front of his class. From there, he recognize almost everyone. He saw Gai, Asuma, Kurenai, Anko, Rin and the two he's been hoping to meet, Kakashi and Obito. They were all looking at him.

"Class, we have a new student. He's started late in the academy, but since we have only started attending class for three weeks, he won't have any problem to catch up to you all."

The sensei then looked at Hiroki urging him to present himself to his class.

"Hello everyone. My name is Hiroki and I hope we become good friends."

"Hiroki, choose any empty seat you find."

Huroki took a look around the class and found an empty spot near Gai and that is were he chose to sit himself.

"Now then, since that is over let's start our lecture. Today we have sparring class, but before that we will have a class about chakra control." The sensei said as he started writing on the board the concepts of chakra control and the many uses chakra had.

After two hours of lecture, the class sensei took out a clipboard that had the name of every student written on the paper.

"Alright class, it is now time for our sparring session. Each person will have two matches with two different persons. Each match will consist of three rounds. The best out of three will win. Let's go outside so we can continue."

After everyone was out the sensei called out the names of those that were to fight. Asuma went against Kurenai and was beaten quite easily as he did not show any resistance. Rin fought against another girl and easily won. Gai went up against Gemma and easily won with his taijutsu. Gai was a hard hitter since young.

"Next match, Obito Uchiha vs Hiroki." The sensei announced.

"Good luck Obito." Rin cheered for him.

Obito had a small blush on his face.

"Do the seal of confrontation. Begin."

Obito went straight for Hiroki's face, only to miss as Hiroki just side stepped and punched Obito in the stomach, making the Uchiha take a few steps back. Hiroki maintained a calm face. Obito then went for a combo, but no matter what he tried, Hiroki would just dodge to the side. Hiroki then moved fast, took out the kunai Minato gave him and pointed it towards Obito's neck.

"First round, Hiroki wins. Second round start."

Obito decided to change his tactic this time and waited for Hiroki to make a move, but lost patience once he saw that Hiroki was not moving from his spot. Obito rushed at him, but then tripped on Hiroki's leg and fell on the ground.

"Second round, Hiroki wins." The sensei announced.

"What? But I didn't lose."

"You stepped out of bounds Obito. Now you two do the seal of reconciliation."

As the two were doing the seal, Hiroki took advantage of the moment to start a conversation with Obito.

"You fought well Obito. You put in good effort." Hiroki said.

"Come on. Are you kidding me? I wasn't even able to touch you."

"It was only due to you lack of patience. You can never head straight against an unknown enemy. You have to be cautious at all times, reel them into a fight you can take advantage of. The last round for example. You were so eager to beat me that you forgot the surroundings and lost because you stepped out of bounds."

"Thank you for helping me Hiroki. I'll keep that in mind." Obito said as they went back to the crowd of students.

Kakashi was the last one to fight. His opponent was Hayate and they fought pretty well. They were on par until Hayate started coughing and lost concentration in the match. As this went on, everyone fought their second opponents. The last match was Hiroki vs Kakashi. Hiroki was quite excited for this match. He knew Kakashi was a genious and he wanted to test himself against him.

"Begin." The sensei announced the start of their match.

For the first time, Hiroki took a stance. Since he used to work for the special ops of his country, he knew many styles of martial arts. His favorite style was Hapkido. Hiroki always let his enemy take the initiative to reel them in and then counter and hapkido did just that.

Kakashi observed him for a while then took a kunai and ran toward Hiroki, who waited for the last moment until Kakashi struck. Kakashi thrusted the kunai towards Hiroki's stomach, but Hiroki side stepped, grabbed the hand holding the kunai and used the force of the thrust to make Kakashi go the opposite way. As Kakashi lost control of the direction he was going, Hiroki tripped him, making Kakashi's back hit the ground. Hiroki used both Kakashi's and his own hands to point the kunai to Kakashi's face, while his knee was on Kakashi's stomach and other free hand, preventing him from getting up.

"First round, Hiroki wins. Second round start."

Hiroki took his own Kunai and rushed towards Kakashi. Kakashi seeing that, tried to counter Hiroki the same way he was countered in the round before. As he got ready to grab Hiroki's arm, Hiroki turned around and tripped Kakashi with his heel, making him fall on his back.

When Hiroki was about to point his kunai towards Kakashi, the later turned into a wood block.

'Substitution, not bad.' Hiroki thought.

Kakashi then appeared behind Hiroki with his kunai pointing to the back of his head.

"Second round, Kakashi wins. Third round start." The senesei announced.

Hiroki and Kakashi took their time analyzing each other. They both had a serious look, but they were both enjoying themselves. Hiroki did not take out his knife and took a different stance. This time he was in a Muay Thai stance. Arms raised to the side of his head and right leg slightly raised. He did not wait for Kakashi and attacked directly. He used elbow, knees, kicks and punches. Kakashi could only block as he wasn't able to dodge any of his attacks. Every time he tried dodging, Hiroki would just throw a punch to that side, forcing Kakashi to block. When Kakashi felt Hiroki slow down his attacks, he attempted a substitution one more time, but just as when he got on Hiroki's back, he was met with a backwards kick. Kakashi could only block using both arms, but the force was enough to send him about five meters away, making him step out of bounds.

"Third round, Hiroki wins." The sensei announced. After that, Hiroki and Kakashi did the seal of reconciliation.

"Very good match Kakashi. I hope we can spar with more frequency." Hiroki said to the silver haired.

"Yeah. I hope to have more matches with you too Hiroki."

"Kakashi yaro. How can you lose to Hiroki? I told you to wait for me to beat you." Obito said as he pointed his finger at Kakashi. Kakashi didn't even pay attention to him, making Obito embarrassed. Obito then looked at Hiroki.

"Since you beat Kakashi and I, I guess this makes you my rival as well. Don't lose to anyone before me alright." Obito said with a smile.

"I'll try my best Obito." Hiroki said with a smile as well.

"Alright class, let's go back inside. There's still our geography class." The sensei said as he urged his students inside the academy.

After class was finished, Hiroki was walking out from the academy together with Kakashi, Rin and Obito.

"Hiroki, what was that type of taijutsu you were using in the spar? It kinda resembled our Uchiha interception fist." Obito asked.

"Yeah. How about that style you used in our last match? I've never seen or heard of a style like that." Kakashi also asked.

"The first one is for self defense. If you use it, you have to wait for your opponent to strike first and then use his own move and strength against him. The second one is opposite. It is used to pressure your opponent and not give him any space. Elbows and knees have more bone mass and do more damage depending were you strike." Hiroki explained to them.

"Wow. You know a lot Hiroki. And you explained it so well." Rin said, complimenting him. This got Obito jealous and he started rambling about his clan's taijutsu. Hiroki just laughed at this while Rin paid attention to Obito and Kakashi looked like he could care less.

As they continued walking, Sakumo arrived to pick Kakashi up.

"Kakashi, ready to go home?" Sakumo asked. Then he noticed and recognized Hiroki.

"Ah. Hiroki-kun. It's good to see you. Are you in the same class as Kakashi?"

"Sakumo-san, it's good to see you are well. Today was my first day in the academy. Kushina ne-san and Minato ni-san helped enroll."

"Oh. That's good. I hope you become a great shinobi in the future Hiroki-kun." Sakumo said. He then looked at Kakashi.

"Kakashi, how was the spar? Remember not to go easy on your classmates, but don't hurt them."

"I won my first match today, but I lost the second one." Kakashi said.

Sakumo knew that Kakashi didn't have any classmates that would win against his son. He has been teaching him since he was 4 years old and he knew his son was no less than a genius.

"That's a surprise. Who won against you?"

"It was Hiroki." Kakashi answered. And this surprised Sakumo even more. He didn't expect that a kid in his first day at the academy would beat Kakashi. Sakumo then came to the only conclusion possible. He thought that Hiroki must be the child of a shinobi family and his parents were teaching him just like he is doing with Kakashi.

"Hiroki-kun, wha family are you from? Who are your parents?" Sakumo asked, but then instantly regretted as he saw how sad Hiroki had become.

Hiroki wasn't sad due to being an orphan in this world, but was sad as he remembered his true family. His father, mother, bothers, wife and children. He remembered how they made him the happiest man alive. As he remembered those moments he lived with them. A powerful surge of chakra flowed through his brain. In the next second, Hiroki got light headed and fainted.
