In the dim, endless tunnel of the first phase of the Hunter Exam, a young boy with unnervingly quiet eyes joins the crowd. His name is Kuro, age fourteen. He possesses a natural talent for observation and a hidden Nen ability he keeps locked away in his heart.
When he teams up with Gon, Killua, Kurapika, and Leorio, his deadpan humor clashes with Leorio while his precise advice impresses Kurapika. On Zevil Island, a split-second metallic gleam on his hands catches Killua's eye—a secret the youn
Hunter x Hunter: Liquid Steel - Cracks in the Mask and a Fateful Name
The spectator seats of Heaven's Arena were engulfed in a whirlwind of frenzy.
Cheers echoed off the walls, shaking the floor. On the 200th-floor ring, Gon was charging straight at his opponent. His spiky deep-green hair was plastered to his forehead with sweat, his large brown eyes tracking the trajectory of his enemy's fists. That was always his way of fighting. No dodging, no tricks—taking the opponent's attacks head-on and pushing right back.
On the ring, the massive man he faced swung down a club.
Gon didn't stop his advance. The instant the club grazed his shoulder, he dropped his body and dove into the man's guard. His fist sank into the opponent's solar plexus. A dull thud shook the air, and the giant's huge frame folded into a V-shape.
"Not done yet!"
He grabbed the collapsing opponent's arm and, in one motion, executed a shoulder throw. The mat shook with a heavy thud.
In one corner of the stands, Kuro sat with his arms crossed, watching. His black eyes glared at the ring. His spine was ramrod straight, like a steel wire. From his left wrist to his elbow, faint silver lines flickered in and out of visibility.
Gon pinned his opponent. The referee began the count.
Kuro's body didn't move a millimeter.
But in the instant Gon was driven into a corner—the moment a counterattack sent him flying backward and his back slammed against the ring—Kuro's upper body leaned forward ever so slightly. A movement of just a few centimeters, one he himself didn't even notice.
"Huh."
Killua, sitting beside him, lifted one corner of his mouth. His silver hair gleamed under the lights. His blue, almond-shaped eyes, reminiscent of a feline predator, weren't watching the ring—they were fixed on Kuro's profile.
(*So he can make a face like that after all.*)
Gon stood up. His opponent could no longer move. The match was decided.
Kuro quietly leaned his weight back against the seat. His face became unreadable once more.
Next was Killua's turn.
His fighting style was the polar opposite of Gon's. He coldly read his opponent's movements ahead of time, never letting them take a single step in. His attacks were minimal. There was no wasted motion whatsoever. It was a precise, merciless match progression, like carving up an opponent with blades of ice.
Kuro watched Killua's match with the same expressionless face. But when Killua locked his opponent's joint and rendered them combat-incapable in an instant, the corner of Kuro's mouth twisted just slightly. It was an expression of dark understanding, directed at someone who inhabited the same world.
The matches ended, and Gon came running up in the corridor.
"Kuro, did you see?! How was my match?!"
His face, shining with sweat, was full of smiles.
"On your opponent's second strike, you shifted your weight too far to the left. If you were going to finish him, that was the moment."
Kuro answered curtly. His gaze wasn't on Gon, but directed at the darkness further down the corridor.
"Huh... oh, maybe you're right! But at that moment, I was still reading his movements—"
Gon didn't mind. If anything, he was seriously replaying Kuro's critique in his head.
"Well, against an opponent of that level, it's not a problem."
Killua joined them from behind. With his hands still in his pockets, he glanced at Kuro.
Kuro said nothing, turned his back on the two of them, and started walking.

That night.
In the city of Lubrica, "Ringside"—the entertainment district centered around the arena—shone like a city that never sleeps. But the room in the Duram Inn was quiet. The walls were thick, and the clamor outside the window was only a distant, faint murmur.
Kuro sat in a chair by the window. In his hands, a cup of cold tea. No more steam rose from it.
The room door opened without a knock.
It was Killua.
"Yo."
Killua entered the room and stood with his back against the door. He crossed his arms and stared down at Kuro.
"What's your real ability?"
He got straight to the point.
Kuro's hand set the cup down. The small sound of ceramic touching ceramic broke the silence.
"...What are you talking about?"
"Don't play dumb. During the plate scramble on Zevil Island—when you slipped into the leader's guard, a silver light ran across your fingertips. It wasn't even 0.3 seconds, but I saw it."
Kuro's black eyes met Killua's blue ones.
"Metallic Skin. You know about it too."
"Yeah, I know. A Manipulation-type ability that cloaks your skin in liquid metal. But that light—that alone doesn't explain it."
Killua took a step forward. The air grew tense.
"Same with the ball grab on the airship. Your movements when you took that ball from Netero—that's impossible with just Manipulation-type body enhancement. It was like you could see the future, choosing the optimal trajectory."
Kuro remained silent.
Killua wasn't pressing him with emotion. Not with sympathy, not with pleading. He was simply trying to expose what Kuro was hiding, as a matter of fact, as logic.
"It's more dangerous for us to stand beside you without knowing."
At those words, Kuro's eyebrows moved just a fraction.
(*He's not viewing me as a danger. He's saying that fighting without knowing is dangerous.*)
"Kuro."
Before anyone realized, Gon was standing at the entrance to the room. His large brown eyes weren't interrogating him. Not blaming, not rushing.
He was just... there.
Faced with that silent weight, Kuro opened his mouth as if resigned.
"...Game State Interface."
His voice was low.
"My true ability is Specialization-type. Once a day, I can freely redistribute my aura affinity across the six Nen types."
"Huh... so that means, like, you're an Enhancer today and an Emitter tomorrow?"
Gon's eyes widened.
"That's right. Depending on the situation, I can become a user of any type."
"That's cheating. But an ability that convenient has to have a restriction."
At Killua's words, Kuro let out a small breath.
"Yeah. If I allocate 80% or more to a single type and use it, for one hour afterward, intense pain runs through my entire body."
Kuro's voice was flat. But just for that part, there was a momentary pause.
"During the pain, using Nen is also impossible. I can't move for an hour."
"You can't move for an hour...? If something like that happened in the middle of a fight..."
"I'd die."
Kuro said it bluntly.
"Aren't you scared, Kuro?! Doing something that dangerous!"
Gon pressed closer. His voice was tinged with genuine worry.
"It's just a little troublesome."
Kuro's reply was so businesslike that it paradoxically revealed he was averting his eyes from his true feelings.
Killua was silent. Then, slowly, he opened his mouth.
"Thanks for telling us."
That was all.
He said nothing more, nothing less. No sympathy, no worry, no advice. He just... accepted it.
A tiny bit of tension drained from Kuro's shoulders. A slight change he himself didn't notice.
Gon silently watched Kuro. In those pure eyes, Kuro was reflected, unchanged.
Between the three of them, a quiet solidarity was born—different from the tension during the Exam.
---
The next day.
Before the sun rose, Kuro was walking down the corridor toward the waiting room.
Photos of past fighters lined the stone walls on both sides. He advanced alone, under the gaze of those countless faces.
Today's match card was posted on the bulletin board.
*230th Floor Ring — Kuro vs. Varec*
When he saw that name, Kuro's feet stopped for an instant. But his expression didn't change. Only the temperature deep in his eyes dropped slightly.
From further down the corridor, he heard footsteps.
A heavy, dragging gait.
The man stopped three meters in front of Kuro.
His iron-gray, close-cropped hair was greasy and disheveled. A deep sword scar ran vertically down his left cheek. His murky gray eyes, with their abnormally dilated pupils, looked Kuro up and down as if licking him all over. His mouth twisted, baring his teeth.
It was Varec.
"...That aura."
Varec's voice was quiet, yet had a sticky quality that clung to the spine.
"The quality of that aura, like liquid metal... You're Gold Heinen's disciple, aren't you?"
Kuro's feet stopped.
It was as if he could hear the sound of all the blood in his body freezing. When he turned around, Kuro's face was no longer expressionless. Something he had sealed away for years was tearing through the surface and seeping out.
"Heehee, that face—priceless."
Varec deepened his twisted grin. Clicking his rings, he whispered at a volume only Kuro could hear.
"That old man, you know... he cried, calling your name, right up to the end."
Kuro's breath stopped.
"'Kuro... Kuro...' he went. He cried with such a nice voice."
Varec's voice coiled around his ears like sweet honey.
"Heeheehee, I'm looking forward to tomorrow. I wonder what kind of voice the avenger of his master will cry with this time—"
Kuro's hand clenched tightly, trembling out of control.
Silver lines surfaced on his left arm, and his fingertips began to change, becoming like liquid metal. His aura swelled, and the air in the corridor trembled.
Laughing, Varec left the scene.
Kuro remained standing, rooted to the spot.
The color had drained from his face, and yet his eyes alone burned with an eerie heat. Anger and pain bound his entire body rigidly.
"Kuro!!"
Gon came running from the other end of the corridor. Killua was with him.
"That just now... who was that guy?"
Killua was momentarily at a loss for words at Kuro's transformation.
"...It's nothing to do with you."
Kuro didn't look at them. He spoke in a quiet voice, but one completely tinged with rejection.
"Don't come."
"What are you saying?! What do you mean, don't come!"
Gon touched Kuro's arm.
Quietly—but clearly—Kuro shook off that hand.
"I'm saying this because you talked to us earlier. This concerns us too."
Killua stepped forward.
Kuro didn't turn around.
His back wasn't the efficient, composed posture from the Exam. His entire body was rigid with anger and pain, clad in a hard, unyielding solitude.
"This is my fight."
Saying only that, Kuro started walking down the corridor toward the ring.
"Wait, Kuro!!"
Gon stepped forward to chase after him.
But Killua grabbed his shoulder and stopped him.
"Let him go for now."
Killua didn't take his eyes off Kuro's back. The gentleness in his blue eyes from the night before was gone, replaced by a cold, analytical gaze.
"Right now, he can't hear anyone's words. He's being consumed by the flames of revenge."
"But, if he goes on like that...!"
Gon's voice trembled.
Kuro's back disappeared into the darkness of the corridor.
The two of them could do nothing but watch him go. From beyond the ring, the cheers of the audience rumbled like an earthquake.
The next match was about to begin.
