If Hinata had the Byakugan, also known as the X-Ray eyes, then Suzuki had the predator vision.
Every living thing emits infrared radiation (heat).
With the help of the "Manager," he used a subtle fire-release flow to sensitize the air in front of his retinas, converting infrared wavelengths into the visible spectrum via a red or blue shift.
His eyes might not have changed, but nothing was hidden from his eyes, and he quickly found where Kurenai was hiding, behind the tree that was three meters away from her position, where she had thrown her kunai previously.
Yes, he had created the so-called heat detector, like the eyes of predatory animals, like those of a viper or a python, making him somewhat resemble Hiruzen's previous disciple, but fortunately, he didn't really like the creepy snake.
Instead, as he had decided to focus on the fire and wind release, it was obvious that he would bring his all with the fire release.
As for why he didn't use the wind release, it was because if he mastered this jutsu so quickly, Hiruzen would be too surprised, as he had just acquired the wind release, but the fire release?
This jutsu was the inheritance that he got from his original parents and despite it not being much, it was the most precious and also the origin of all of his success since without it, he knew well even if he had the "Manager," it was impossible to attract Hiruzen's eyes, and because of that, this time, he would show all of the possible development jutsus that that he had crafted with the help of the "Manager."
Meanwhile, Kurenai, who didn't know that Suzuki had discovered her position, started to think about how to take down this naughty boy, who had just graduated.
No, she wouldn't hurt him, as hurting Suzuki would hurt her much more, especially when he was the disciple of the Third Hokage.
Yet, to defeat him without hurting him?
Was it possible for her?
'Also, what is that jutsu?'
Kurenai thought that it was a genjutsu, but as she tried to break away, no matter how many times she tried, Suzuki was there, and didn't seem to be hurt even if several kunai stuck to him, or rather, he had become intangible!
'Can he transform his body into that of a fire?'
This possibility startled her, and she somehow understood why Suzuki could become Hiruzen's disciple.
"A jutsu that makes him able to turn into fire?"
Hiruzen, who observed the duel, also murmured, realizing that Suzuki's talent was more frightening than he had thought it to be.
Was it an innate ability?
No, this came from intelligence, and Hiruzen was sure of it, and that was why Suzuki was the most perfect disciple for him.
Still, while they misunderstood his ability, Suzuki, who was just standing two meters away from his mirage copy, decided to show his capability with the fire release!
"Kurenai-san, you should dodge since this time, I will get serious."
"....."
Kurenai was in a daze, wondering what this boy was saying. After all, no matter how strong Suzuki was, he was just 12 years old, and somehow she realized how much she had underestimated him.
The hand signs were smooth and short, or rather, in most cases, even without using his hand signs, the "Manager" could help him perform the jutsu, but for the sake of the performance, as he was too lazy to explain why he didn't have to do the hand signs, he used his flame jutsu instead, which was different from the usual.
"Katon: Seien no Jutsu (Fire Style: Azure Flame Jutsu)."
It was just a fireball, like the C-Rank Jutsu that he often used, the Fire Release: Great Fireball Technique, but this time, he added a twist to make it more powerful.
Yet for Kurenai, Hinata, Shino, Hiruzen, and those who saw it, the intense heat of this flame sent a chill.
Fire requires: Fuel + Oxygen + Heat.
Instead of just "breathing fire," he used his "Manager" to alter the oxygen mixture in his lungs through chakra, employing combustion engineering. When that happened, a blue feral flame emerged for the first time on the field.
The intense heat was unbearable, and those who were close subconsciously closed their eyes, as it was so bright.
Yes, this jutsu wasn't huge, and it was just a few meters in diameter, yet even so, it was like the sun suddenly appeared in front of them, and for Kurenai, who was at a loss, she was in disbelief, watching how the blue flame moved in the direction where she hid.
There were many thoughts within him, first was at how Suzuki was able to create those blue flames, and second, how he found his hiding place, but at that moment, as she was in a daze, she was suddenly pulled away, dodging, as she saw the blue flame burn everything into ashes.
Usually, the affected area would just turn red or blistered, yet after being burnt by this fire, everything that was hit immediately turned a dull, brittle matte black.
A sharp, metallic, or ozone-like scent ionized the air around it as the "cracking" sound echoed.
Whether it was Hinata or Shino, whose eyes had recovered, was in a daze, feeling their skin was little dry as they gulped, but Kurenai... she was just on his arms, staring at the burning scene at a loss.
"Are you okay, Kurenai-san?"
"Ah, um, yes."
"Sorry, it seems that the damage from my jutsu is bigger than I had imagined."
Suzuki also felt his body was a little dry and hot, but fortunately, he had the chakra and had learned how to wield the water nature, so he quickly tried it to cool down the temperature around him, Kurenai, Hinata, and Shino.
"I lost."
"Eh?" Kurenai looked at him, dumbfounded, feeling confused since no matter how one said it, the victor was Suzuki.
However, Suzuki was at his limit, especially after he had used everything he had on this jutsu to protect Kurenai. He thought that Kurenai would react and escape, but unexpectedly, she just rooted in place, which made him wonder how this woman could even become a jounin, or was a jounin this weak?
Or, was his "Manager" really that strong?
Regardless, he breathed heavily as he fell onto Kurenai's soft, warm bosom.
Yup, he was petty since as Kurenai had troubled him, it should be okay for him to take a little advantage of her, right?
Still, he had to say the softness of a mature woman was different.
"Suzuki!"
