The first blow came without warning.
Aldebran stepped forward with a short, compact movement, his fist cutting through the air with terrifying density. There was no wasted motion, no visible flourish—only raw intent compressed into a single strike. The impact landed squarely against Meruem's abdomen.
For the first time since entering the underground chamber, Meruem was sent sliding backward.
His feet scraped across the stone floor, carving thin grooves as his body absorbed the force. A dull shock rippled through his core, deeper than pain, deeper than surprise. His breath escaped him in a sharp exhale, and his tail lashed once behind him, reacting before his mind could fully register what had happened.
So… this one is different.
Meruem straightened slowly, violet aura beginning to pulse more visibly around his frame. His expression did not twist in anger, but something colder settled behind his eyes. Until now, he had measured his opponents. Now, he acknowledged one.
Aldebran remained where he was, shoulders relaxed, arms loose at his sides. The stone beneath his feet was cracked, not from movement, but from pressure alone—his aura sinking into the ground like an unseen weight.
"You felt it," Aldebran said calmly. "Good. That means you're still conscious."
Meruem answered by vanishing.
The floor shattered where he had stood as his body surged forward in a single explosive leap. His arms distorted mid-motion, muscles elongating and sharpening, the flesh reshaping into curved, blade-like extensions that gleamed faintly with aura.
"Scythe Form: Violet Severance."
The strike came in a sweeping arc, aimed not at Aldebran's body, but at the aura surrounding him—an instinctive choice. Meruem had sensed it the moment they clashed. Something about Aldebran's Nen was wrong. It wasn't simply strong.
It was structured.
The blades collided with an invisible surface.
A sound rang out—half metal, half resonance—as Meruem's attack was stopped short, his aura slicing into something that bent but did not break. Aldebran had not moved. His eyes narrowed slightly, more in interest than concern.
"So you noticed," he said. "Most don't."
Meruem twisted mid-air, flipping backward to create distance. He landed lightly, blades retracting as his arms returned to their original form. His aura flared higher now, deeper in color, more unstable.
"That aura," Meruem said. "It flows… but it resists. Like liquid steel."
Aldebran smiled faintly.
"My Nen isn't just reinforcement," he replied. "Enhancement is my foundation—but I refined it. Gave it shape. Weight. Meaning."
As he spoke, his aura thickened visibly, condensing around his forearms and chest. Veins surfaced along his skin, glowing faintly beneath the pressure. The air around him distorted, as if heat were rising from his body.
"I call it Axiom Mantle," Aldebran continued. "An ability born from years of forcing my aura to obey form without losing motion. Solid enough to stop you. Fluid enough to move with me."
He clenched his fist.
The aura hardened, taking on faint geometric contours, almost like invisible armor etched with ancient lines.
"This same principle," he added, "is what allowed me to create the cube."
Meruem's gaze flicked briefly toward the shattered remains of the prison behind them. The chimera ant that had once been sealed within was no longer bound—but remained strangely still, seated cross-legged on the floor, eyes closed, aura circulating in slow, deliberate cycles.
Aldebran followed his glance.
"A failed experiment," he said. "Contained using layered materialization reinforced by enhancement. A living seal."
Meruem returned his focus to Aldebran. "You speak as if control is absolute."
"It is," Aldebran replied, stepping forward. "When discipline surpasses instinct."
He moved.
One step—then another—and with each motion, his aura pulsed outward in controlled bursts. His fists began to move, not wildly, but in rhythm. Each strike split the air like a hammer blow, the sound echoing through the underground halls.
"One."
Meruem blocked, crossing his arms, the impact driving him back.
"Two."
A knee followed, reinforced by compressed aura. Meruem twisted aside, the shockwave tearing through the wall behind him.
"Three."
A palm strike. The floor cratered.
The building trembled.
Above them, dust rained from the ceiling of the library. Shelves rattled. Somewhere far above, glass shattered.
Meruem retaliated, his body adapting with each exchange. His movements grew sharper, more efficient. He slipped between blows, countering with claws, tail strikes, bursts of raw aura.
Their Nen collided again and again—pressure against pressure, form against evolution.
Yet something was wrong.
Meruem felt it with growing clarity.
Each time he exerted himself, something inside him resisted. His aura surged—but faltered. His body responded—but slower than it should have. Hunger clawed at his core, not as desire, but as absence.
Since his awakening… he had consumed nothing.
Not enough.
Between human fragility and chimera potential, his body demanded fuel—and now, under true strain, it was calling in its debt.
Aldebran noticed.
"You're slowing," he observed, dodging a strike by a breath. "Your aura fluctuates."
Meruem said nothing, forcing his power higher, ignoring the warning signals screaming through his nerves.
Then—A sound.
A deep, resonant crack echoed through the chamber, different from the chaos of battle. Both fighters froze instinctively, senses flaring outward.
From the remains of the cube, aura surged.
The chimera ant opened his eyes.
They glowed faintly, not with rage, but with clarity.
He rose slowly, joints cracking as Nen flowed through limbs that had been dormant for far too long. His posture straightened, his presence expanding until it pressed against both combatants like a third force entering the field.
"Enough," he said calmly.
Aldebran turned sharply. "Impossible…"
The chimera ant stretched his arms, rolling his shoulders as if testing a long-forgotten body.
"I owe you an explanation," he said, looking directly at Meruem. "And… an apology."
Meruem did not attack. His instincts screamed, but something held him still. Curiosity. Recognition.
"You told me," Meruem said, "that your mother was a renegade."
The chimera ant exhaled slowly. "A lie. One I told to survive."
He stepped forward, stopping several paces away. His aura was refined, disciplined—clearly awakened through prolonged meditation rather than battle.
"My name is Kaelreth," he said. "Commander of the Royal Guard of the Seventh Queen of the Cursed Beasts Isles."
Aldebran's eyes widened slightly, but he did not intervene.
"The one you know as a renegade," Kaelreth continued, "was her daughter. She fled—not out of rebellion, but choice. She sought to build something new. A kingdom free from endless cycles of dominance."
He looked at Meruem intently.
"Our Queen loved her. Feared losing her. That is why I was sent—not to kill… but to retrieve."
Kaelreth clenched his fist, aura trembling.
"I failed. I was captured. Studied. Sealed."
He met Meruem's gaze, voice lowering.
"But when I sensed your aura… I knew. Whatever you are—you are not ordinary."
Aldebran stepped forward, aura rising once more. "Enough. This changes nothing."
Kaelreth turned slightly. "Doesn't it?"
Meruem felt it then—a subtle pull. His body moved before thought, a sudden step forward, aura flaring instinctively as his presence bore down on Kaelreth.
For a fraction of a second, even Aldebran lost sight of him.
Meruem stood before the chimera ant, eyes glowing, aura surging dangerously close.
"We are not here for your past," Meruem said quietly. "Nor your loyalties."
Kaelreth smiled faintly, unafraid.
"Then perhaps," he replied, "we are here for what comes next."
Silence fell.
Aldebran's aura surged again, heavier than before. Meruem's violet Nen responded in kind. Kaelreth's presence lingered between them like a question left unanswered.
The ground beneath their feet cracked once more.
The building groaned.
And though no strike was thrown—
The air itself seemed to hold its breath, uncertain of whether the next moment would bring annihilation… or revelation.
