More importantly, the Nature Transformation of the Yang Attribute.
The Yin–Yang Attributes are mysterious powers. Both of their Nature Transformations belong to secret arts—like the Nara Clan's shadow techniques, the Akimichi Clan's Multi-Size Technique,
And the Yamanaka Clan's Mind-Body Switch Technique. There are even higher forms of Yin–Yang Release, such as the Six Paths Black Rods.
Among them, what Kairen valued most was the Akimichi Clan's partial Multi-Size Technique. Why?
Those who know, know.
The Yang Attribute, a force born from the life energy that governs vitality, grants form to life.
Simply put, mastering the Yang Attribute could elevate Kairen's Transformation Techniques by more than a single level.
Without hesitation, Kairen immediately spent 5000 points to exchange for a Forbidden Jutsu Development Card, this time using up all his remaining experience points.
Yesterday's Fire Release: Blazing Flame Dragon technically counted as a Forbidden Jutsu, but that was only because of its power level. In terms of developmental principle, it wasn't truly at the level of a Forbidden Jutsu yet.
This time, however, the Transformations technique he was developing was truly of forbidden level.
Kairen immediately commanded the system to activate the Forbidden Jutsu Development Card!
"System, help me develop a Forbidden Jutsu that allows me to transform into any real object!"
[Detection complete. Host meets the basic conditions for Ninjutsu development. Forbidden Jutsu Development Card successfully used. Ninjutsu development in progress!]
[Development progress 1%...]
[Development progress 10%...]
[Development progress 50%...]
[Development progress 100%!!]
[Since the host's Forbidden Jutsu is of a growth-type nature, the host must personally record transformation targets.]
In simpler terms, Kairen had to copy whatever he wanted to transform into. Relying on imagination alone would make the form incomplete—too many "censored" areas, not enough frame detail.
[Forbidden Jutsu development complete. Please name the technique!]
Kairen thought for a moment. He wanted to call it "Seventy-Two Transformations," but that sounded too plain, not grand enough.
So he declared, "Let's call it Secret Art: Hundred Transformations!"
Originally, he'd planned on naming it "Kairen's Hundred Transformations," but ended up reversing the words to make it sound better.
[Name registered. Forbidden Jutsu Hundred Transformations recorded in the Forbidden Jutsu Archive!]
The Hundred Transformations technique gradually circulated within Kairen's mind.
Hand seals, chakra circulation, chakra pathways—and beyond that, transformation formulas, gravity equations, dynamics formulas, structural analysis, even the periodic table of elements...
Kairen groaned and rubbed his head painfully. This technique touched upon everything between heaven and earth—even the truth of molecular structure transformation and elemental variation.
Yūhi Kurenai saw him and grew worried. She gently massaged his head.
"Kairen, what's wrong? Does your head hurt?"
Shizune, not to be outdone, pressed her hand to his forehead to check his condition.
"I'm fine!"
Kairen shook his head. The torrent of data had flooded his brain in an instant—his mind nearly revolted, ready to overthrow its tyrannical owner.
After taking a few steady breaths, the pallor on his face slowly faded.
He opened his eyes, which now shimmered with the light of worldly truth.
In that moment, he seemed to have reached a higher state of intellect—everything he looked at was automatically accompanied by physical formulas.
He glanced at Yūhi Kurenai's chest.
"Still no A-cup. Kurenai, you really have to work harder."
"Kairen, what are you talking about?"
Kairen quietly activated his Byakugan, scanning Kurenai's body structure.
[Scanning Ninja Yūhi Kurenai's 3D structure: 1%...]
[2%...]
[20%...]
[50%...]
[100%...]
[Recording complete. Transformation model for Ninja Yūhi Kurenai added to Forbidden Jutsu Hundred Transformations Archive.]
To achieve a fully realistic transformation, the model of the target body had to be recorded—only then could chakra accurately mimic that person's physical traits.
Kairen formed a single half-seal for Transformation Jutsu.
With a "poof," white smoke billowed out—
And another Yūhi Kurenai stood before them.
Kurenai looked in surprise at the version of herself standing across.
"Kairen, why did you use Transformation Jutsu—and why into me?!"
Kairen looked into the mirror. Long, silky black hair. Bright red eyes. A round, lovely face.
A sly smile tugged at his lips, mirrored by Kurenai's reflection—an expression both beautiful and strange.
This wasn't the same as ordinary Transformation Jutsu. That kind of technique could only be maintained briefly and would revert at the slightest hit.
Kairen's Hundred Transformations, however, was real. Every detail was formed by chakra itself—even within the body, his chakra simulated Kurenai's exact structural features.
Only when his chakra ran dry, or when its flow was violently disrupted, would he revert to his true form.
"Enlarge!"
Under Kurenai and Shizune's astonished gazes, Kairen activated the technique.
The transformed Kurenai began to grow taller, reaching over 1.6 meters in height.
Her black hair shimmered like silk, her fair arms peeked from red-and-white silk robes, and her crimson eyes carried an intoxicating allure.
She radiated the charm of a mature, seductive woman.
Kurenai circled him several times. "Kairen! Kairen, is this what I'll look like when I grow up?"
Kairen didn't answer. Speaking in a boy's voice from this gorgeous woman's body would instantly ruin the mood.
"So pretty!"
Shizune looked on with admiration. The adult version of Kurenai was like a refined evolution of her youthful self—truly stunning.
Kairen stared at his reflection, silently sighing. Grown-up Kurenai was breathtakingly beautiful. It was such a pity she'd end up with Asuma someday… so he wouldn't hold back this time.
Too bad she was still too young right now—he'd have to wait another six or seven years before she was "ready to eat."
"Release!"
With a seal, he dispelled the transformation and returned to normal.
He didn't feel like transforming into people anymore. He wanted to try an animal next.
He looked around.
"Woof!"
A bark drew his attention. A noblewoman walked by, leading a small yellow dog.
Kairen quickly averted his gaze. After living as a dog for over twenty years in his past life, he swore never to become one again.
"Chirp—!"
A white-headed falcon soared across the sky. Kairen's eyes brightened.
He picked up a pebble from the ground and flicked it upward—the falcon dropped from the sky in a flash.
With a sudden Body Flicker, Kairen caught it mid-air in one hand.
Activating his Byakugan, he began scanning its body structure.
[Scanning small raptor (Falcon) 3D structure: 1%...]
[10%...]
[50%...]
[100%!]
[Small raptor (Falcon) transformation model successfully recorded!]
Kairen gently stroked the falcon's head. The gentle chakra of the Senju Clan flowed through his hand, healing the spots where the falcon had been struck.
Sensing Kairen's warmth, the falcon gradually calmed.
When it recovered, it affectionately nudged his hand—then Kairen tossed it back into the air.
"Chirp—!"
The falcon spread its wings and soared freely into the skies, gliding across the heavens—so free, so unrestrained.
A confident smile spread across Kairen's face. He formed seals, blue chakra flames rising around him.
"Hundred Transformations: Falcon Form!"
With a loud "poof," the smoke cleared—Kairen had transformed into a massive falcon!
His wings stretched over five meters wide, and from talon to head, he stood nearly three meters tall.
Hadn't he always called himself the "Son of the Falcon"? Well, fiction or not—today, he'd make it real.
He had become a true falcon—soaring to the skies and gazing down upon the world below.
"Look over there! Someone turned into a giant eagle!"
The townspeople who had been watching a street performer's Transformation Jutsu turned to stare at the enormous falcon overhead.
"So big! And so dark!"
"And what majesty!"
"It's not like an eagle—it is one! Such killing intent!"
The street performer went pale. It seemed a true master had arrived to steal his spotlight.
Yūhi Kurenai and Shizune hurried over, looking up at the magnificent bird in the sky.
White head, black feathers, eyes sharp and vivid.
Kurenai was the first to shout, "Kairen, what are you doing?! You just turned into me—now you've become an eagle?! Change back already!"
Kairen glanced down. The Forbidden Jutsu Hundred Transformations was far from simple—it even replicated the falcon's vision.
A falcon's optic nerves are six to seven times stronger than a human's, seeing details far more precisely. Combined with the Byakugan, he could now perceive distances of over ten kilometers.
Shizune gently touched his feathers.
"It feels so real… This doesn't seem like ordinary Transformation Jutsu."
She plucked a feather—it slowly disintegrated into the air once its chakra supply ended.
"Whoosh—"
Kairen spread his wings wide and rose up with powerful flaps.
He had always longed to fly—to master some flight technique.
He'd even considered exchanging for the Super-Lightened Boulder Jutsu or the Hidden Star Village's Mysterious Peacock Method.
But now, there was no need.
He could already simulate the flight of a bird.
