Chapter 33: Test Version Blut Arterie
"Nervous?"
"…Yeah."
"Don't be. Everyone out there came to witness your ability."
In the quiet preparation room, Aizen Sosuke stood beside Kakashi, who looked uneasy. With a faint smile, he rested a hand on the young ninja's shoulder—firm, but reassuring.
It wasn't a patronizing pat on the head. It was the gesture of one man acknowledging another—a mark of trust.
And somehow, that single touch eased the tension in Kakashi's chest. The nervousness faded.
But something else surfaced in its place.
Fear.
Even without trying, Kakashi could hear the muffled clamor beyond the walls—the low hum of voices, the shuffling of countless footsteps.
Unlike the Blut Vene, which had been developed in secrecy, this new creation demanded exposure. Defense was important—but offense was the true language of power.
The Blut Arterie was Konoha's declaration to the world: its offensive strength had evolved. That fact alone made the village elders proud… and dangerously complacent.
From the sound of it, the viewing platforms outside were packed. Ninjas—elite ones, veterans, commanders—had come to see the results for themselves.
Even Hatake Kakashi, who rarely showed fear, couldn't help but feel it now.
What if they rejected his work?
What if it failed?
Those thoughts clung to his mind like shadows, feeding his anxiety until fear began to twist into something colder—terror.
He was only seven. Barely even that.
His body stiffened. Without realizing it, he took a step back.
But a steady hand stopped him.
Aizen Sosuke.
The man who always smiled softly—who seemed untouchable, yet endlessly calm—was now blocking his retreat.
"After nervousness comes fear, hmm?" Aizen said quietly.
Kakashi looked up, startled.
Aizen pushed his glasses and smiled, his voice as smooth as silk. "Unexpected, but not unwelcome. You're finally behaving your age, Kakashi-kun. That makes me quite happy."
"What's so happy about that…" Kakashi muttered.
"Because it means you're alive," Aizen replied gently. "You're no longer living in your father's shadow. You've begun to form your own thoughts… your own will."
Kakashi said nothing.
Aizen chuckled softly. "Ah, forgive me. I was too direct."
He turned toward the locked door, his tone steady and composed.
"You're still afraid, I know. But fear, Kakashi-kun, is just a form of self-inflicted pain. It changes nothing. Fear is simply the mind attacking itself."
He looked back at the boy, his smile widening slightly.
"But what comes from fear—that's what matters. Will you run because of it, or will courage be born from it? That choice defines how you shape the world."
He raised his hand slightly, his tone turning soft yet absolute.
"If you let fear paralyze you, you'll accomplish nothing. But if you take even one step—forward or backward—it's still an action. Only through action can thought become reality. Otherwise, all your ideals remain illusions."
He paused.
"Real people don't fear—they act. You can choose to flee and let me take your place. Or you can stand still and become a laughingstock. But the third choice…" Aizen's eyes gleamed faintly. "The one most fitting for you—is to step forward and stand in the light. Face those who doubted you. Prove them wrong. Show them what you've built. That is the answer I believe you'll choose."
Kakashi remained silent, staring at the floor.
It was, as always, the essence of Aizen's persuasion—
gentle arrogance wrapped in compassion, a warmth that carried the weight of authority.
And somehow, it brought an undeniable sense of safety.
Kakashi closed his eyes. In his mind, fragments of memory flickered—the months he had spent under Aizen's roof, the endless research, the scrolls filled with calculations, the quiet lessons whispered between cups of tea.
He knew the truth: the Blut Arterie was far beyond theory. What Aizen had given him was a simplified model, along with a few technical scrolls that explained how to balance its unstable energy.
Though similar in name, the Blut Arterie and Blut Vene were two completely different entities.
The Blut Vene used chakra's natural energy—engraved within the body—to harmonize strength and external flow, condensing it into a defensive barrier upon the skin.
The Blood-Moving Equipment, however, was the inverse. It absorbed and weaponized external energy to amplify one's own power, multiplying the force of ninjutsu and taijutsu severalfold.
But it came with a curse.
For reasons no one had yet deciphered, when this external energy reacted violently with the human body, it caused catastrophic side effects—calcification of flesh, petrification of limbs, and in the worst cases, complete mutation of organic tissue.
Those who failed to master it turned into living stone—monuments to the cost of ambition.
And the energy itself… was alive.
An enraged, chaotic force that never ceased to burn, scream, or destroy.
Aizen had proposed several isolation and extraction methods, but only outlined a few broad concepts for stabilizing this violent external energy. After rejecting a series of risky modifications that could endanger the human body, Kakashi finally decided on an approach modeled after the Blut Vene.
Using a sensing liquid inscribed with specialized tracings, and with the internal vein map provided by the Hyuga clan's Byakugan lineage, Kakashi designed a network that rerouted chakra into external and internal circuits. These twin channels intertwined one-to-one, forming what he called the Perfect Holy Body—a living system that could siphon external energy in harmony with the user's own chakra.
In this state, physical vitality surged dramatically. The five senses sharpened to their limits, perception expanded, and both taijutsu and ninjutsu were amplified nearly twofold.
But the price was steep.
If the body suffered severe trauma, the connection with the Perfect Holy Body would immediately sever, returning the user to normal.
To Kakashi, this prototype Blut Arterie was far from perfect. But the Third Hokage deemed it more than enough.
After all, it fit perfectly into the envisioned three man formation—one with the Blut Vene for defense at the front, one with the Blut Arterie for offense at the rear, and a medical ninja stationed between them.
A flawless structure.
Kakashi's expectations for himself were never high. Yet for many watching, even a single demonstration would be proof enough.
Yes—there was nothing to fear.
The theories had been tested. Combined with Aizen's specialized sensing reagent and the built-in safety mechanism, the risk of failure was virtually zero.
Kakashi opened his eyes slowly. The noise outside returned to his ears, no longer harsh or doubtful, but full of anticipation and curiosity.
"I'm going, Aizen," he said quietly. "Just watch."
"I look forward to it, Kakashi-kun."
Aizen smiled, adjusting his glasses as the boy stepped toward the door.
The moment Kakashi appeared, the crowd fell into murmurs. Even among seasoned jonin, few could mask their curiosity.
At the center of the testing arena, Jiraiya stood tall—arms folded, a faint grin tugging at his lips. "Finally showed up, huh? Took your time," he called out, laughing boisterously as he waved at the stage.
But when Kakashi emerged from the corridor, his composure was calm—almost too calm. The young ninja's silence contrasted sharply with the noise around him.
Jiraiya's grin faded. He tilted his head, recognizing the small canister in Kakashi's hand.
"It's Hatake Kakashi, right?" Jiraiya said with a faint chuckle. "You don't need to push yourself too hard. I've already prepared the Blut Vene and some inner linings. Just take it easy. You're still a Chunin—leave the hard part to me."
Kakashi said nothing.
Without a word, he uncapped the vial and poured the liquid over his head.
The reagent spread instantly, cool and precise, sliding across his scalp, down his neck, and over his skin.
He closed his eyes. His palms came together in a sharp clap.
A single, clear sound echoed.
"Blut Arterie"
The liquid flowed like living ink, splitting at his eyebrows before solidifying into two dark markings that streaked down his face.
His veins glowed crimson. Chakra pulsed through them, swirling like a tide, racing through every muscle, every joint, every bone.
The transformation completed in less than a second.
When Kakashi's eyes opened again, the pitch black pupils shone with eerie light—meeting Jiraiya's wide, startled gaze.
"One."
Then he vanished.
A powerful impact slammed into Jiraiya's shoulder before he could react—like being struck by a seasoned taijutsu master. A split-second later, a deep rumble followed, and a gust of air burst outward across the arena.
The viewing platforms shook.
Snacks and scrolls flew into the air.
The crowd erupted into startled shouts.
But Jiraiya couldn't care less.
He turned, stunned, to see the faint red afterglow of chakra around Kakashi's form. The Blut Vene's barrier—reinforced and flawless—was already spiderwebbed with fractures.
Lightning danced faintly along Kakashi's brows, pulsing with controlled rhythm.
The markings across his body shimmered between light and dark, as if breathing.
The meridians beneath his skin glowed like burning lines of chakra.
For a moment, it was as if he stood before something divine.
Jiraiya's eyes widened, his breath catching in awe.
"This… this isn't just some Blut Arterie…" he muttered, voice trembling with disbelief.
He clenched his fists and shouted, his laughter echoing across the arena.
"This is sorcery—no, this is art! A brand new Sage art!"
The words hung in the air like thunder, swallowed by the roar of the crowd as Konoha's shinobi witnessed the birth of something extraordinary.
