"Come to think of it, you still haven't introduced me to your girlfriend."

"Hehe, isn't that because you're usually too busy, Big Brother Shiro? This is my girlfriend, Saori." Then he turned to Saori and said, "Saori, this is Big Brother Shiro. He's a Chunin!"

"A Chunin? At such a young age? That's amazing!"

"Haha, it's nothing. You two will definitely be stronger than me someday." If Shiro didn't die first, that was.

"Really? Big Brother Shiro, can I do it too?"

"Yeah, you can, as long as you work hard. Come on, before they finish cooking, let's go see how well you've learned the ninjutsu I taught you."

With that, he led Okita and Saori behind the house. Since both families' children had talent as ninjas, they had worked together to build a training ground behind their homes.

However, Shiro generally did not train here. After all, if he damaged anything, he would have to pay for repairs himself. Public training grounds were different; unless one caused major damage, there was no need to take responsibility. Thus, Shiro usually went to the public training grounds.

"Hehe, just watch, Big Brother Shiro. I won't disappoint you!"

"Ha, then I'll look forward to it."

Once they reached the training ground, Shiro and Saori stood in the back while Okita stepped forward and stood before the target. He first took a deep breath to relax, then began forming hand seals.

"Wind Release: Great Breakthrough!!!"

"Bang!"

Shiro stared in surprise at the target, which had been struck hard enough to sway. Though its speed and power were nowhere near C-rank, he had truly managed to cast it. He was only a little over six years old!

"That's amazing, Okita!" Saori cried out beside him like a fangirl.

"Hehe, how was that, Big Brother Shiro? I did pretty well, right?"

"Mm. Your hand seal speed and power still need work, but for your age, you've done very well. Still, there's something I don't understand."

"Mm? What's wrong, Big Brother Shiro?"

"Why did you shout out the name of the ninjutsu?"

That was right. Okita had shouted "Wind Release: Great Breakthrough" just now, while Shiro and the others usually recited it silently in their minds. (Mainly so you readers could understand it.)

"It has more presence that way! And if I don't shout it out, how will anyone know what I used? That would be boring."

"..."

"Besides, I designed a tactic too. I'll shout Wind Release, then use Fire Release! How about that? Awesome, right?"

"Sigh..." Looking at Okita's face, practically screaming for praise, Shiro sighed before ruthlessly crushing his fantasy. "Awesome my ass. There are two problems. First, shouting the name affects the time it takes you to cast the ninjutsu. In future battles, every second will matter."

"Second, what is the purpose of this hand seal?" As he spoke, Shiro formed a hand seal.

"Uh... to guide Wind Release Chakra." Okita pondered for a while before giving his answer.

"Not bad. Your basics are solid. Then tell me this: even someone who hasn't graduated like you knows that. Do you think you can really fool them? Of course, your plan might succeed, but it isn't worth it."

"But overall, not bad. Keep it up!"

"Got it, Big Brother Shiro!"

"By the way, Saori, what Chakra nature do you have?"

"Eh? Me? I don't know."

Hearing that, Shiro looked at Okita in confusion. "You didn't test her?"

"Uh, I forgot. Ha... ha..." Okita smiled awkwardly.

"..."

He really had a big heart. Wasn't he afraid someone would snatch her away? Shiro shook his head speechlessly.

"Perfect timing. I have a sheet of Chakra paper here. Give it a try and see what nature you have."

As he spoke, he handed over the test paper. However, Saori did not take it and instead said, "That's too much trouble, Big Brother Shiro. There's no need. I'm not learning ninjutsu yet, so I don't need it."

"Take it. You'll be learning soon enough. Okita is my little brother, and you're his girlfriend, so we're family. Why be so formal?"

"Then... all right. Thank you, Big Brother Shiro. But how do I use it?"

"It's simple. Just channel Chakra into it. Wrinkling means lightning, splitting means wind, burning means fire, crumbling means earth, and becoming wet means water."

"Mm, I understand."

Then Saori began channeling Chakra into it while Shiro and Okita watched from the side.

As Saori poured Chakra into the paper, it changed. First, it split down the middle. Then one half wrinkled while the other half caught fire!

"It split, wrinkled, and burned—three! That's incredible, Saori! You have three Chakra natures!" Okita happily rushed over and hugged Saori.

"Okita, let go of me! Big Brother Shiro is still here!" Saori said, her face red.

"Hehe, so I can do it when Big Brother Shiro isn't around?"

"You're dead!"

Shiro ignored Okita's lovey-dovey display and stared at Saori in astonishment. Three Chakra natures were an extraordinary talent even in Konoha, not to mention that hers were the three most offensive natures.

Still, how should he put it? Shiro felt a little sorry for Okita. That gentle, delicate-looking girl possessed nothing but offensive Chakra natures. She would probably become another Sakura someday.

"Heh, Okita, don't celebrate too early. You need to train hard too. If you fall behind, some melodramatic plot might happen."

"Uh, Big Brother Shiro, you're saying weird things again."

"Ha, just listen for fun. So, Saori, which type of ninjutsu do you want to learn? I know all three."

Mm, it wasn't a bug. Shiro really did know them, but aside from wind, the others existed only in theory. Because of the issue with his origin, Shiro could only use Wind Release; he could not even cultivate the other natures.

Still, teaching others was not a problem at all.

"Really? Thank you, Big Brother Shiro! Then I'll choose Wind Release."

"Mm? Are you sure? Okita can teach you Wind Release. You can choose a ninjutsu of another nature from me."

"Mm, I'm sure, Big Brother Shiro. If it's Wind Release, I can train with Okita normally. Besides, Wind Release is already enough for me to train with right now."

"Is that so? Then I'll still teach you Great Breakthrough. Once you can use Great Breakthrough proficiently, I'll teach you other ninjutsu."

"Wait, Big Brother Shiro! I can already use it. Hurry and teach me the next ninjutsu!"

"I said use it proficiently. You're still far from that. Besides, do you have any Chakra left now?"

"Uh... n-no."

"So, be good and master Great Breakthrough first. What you have now is enough for you two. Be careful not to bite off more than you can chew."

"Got it, Big Brother Shiro," Okita answered dejectedly.

"Phew... I finally fooled him." Seeing that Okita believed him, Shiro quietly let out a breath in his heart.

In truth, Great Breakthrough was the only Wind Release ninjutsu Shiro could use right now. The others remained theoretical and could not yet be cast. He could hide the other-nature ninjutsu by saying their natures were incompatible and inconvenient to cast, but if he did not demonstrate Wind Release, it would be hard to explain.

Of course, Shiro was not fooling Okita. His foundation really was not solid enough and needed more polishing. It definitely was not because Shiro was afraid of embarrassing himself. Mm, that was exactly it! Serious face!
