The white void was silent, save for the heavy, ragged breaths of the Nexus Seven. Tanjiro, the moral center of the group, was still shaking, kneeling where the Arbiter had pinned him, tears drying on his cheeks. He had been tricked into becoming a murderer.
Jin-Woo stood motionless, staring at the spot where the hologram of a devastating Red Gate had appeared over Seoul. He was a Monarch, used to absolute authority, but here, he was utterly powerless against a concept stronger than death: Malak's Control.
Gojo had his sunglasses back on, but his usual cocky facade was cracked. "Unacceptable," he muttered, his voice cold. "To use my home, my students... that's a violation of the highest order."
Saitama was the quietest. His face, usually empty of expression, held a faint, rare hint of genuine, focused anger. He had accepted the Arbiter's rules for the sake of the 'challenge.' Now, he realized the challenge was rigged, and the stakes were his friends.
Kazuma was pale, not because of the Titans, but because of the reality of the threat. "My world... Aqua's terrible goddess reputation is the only thing keeping it together. If he breaks the rules, I can't even rely on divine intervention..."
Dazai was the only one who looked marginally amused. "Ah, the Faustian bargain. Such a cliché. I'm disappointed in the Matriarch's choice of plot device, but the high stakes add some much-needed literary weight."
Jin-Woo stepped forward, addressing the empty space where the Arbiter had been standing, knowing Malak was listening.
"We are Monarchs, Sorcerers, and Heroes," Jin-Woo said, his voice hard. "Our worlds are protected by laws of magic, spirit, and physics. You cannot simply 'break' them."
The Arbiter's voice—that discordant harmony of scream and choir—echoed in reply.
"I wrote those laws, Monarch. You saw the holographic projection. Your ultimate form of power, the Shadow Monarch Authority, was merely a temporal leak—a concept I allowed to manifest for a moment. I can erase your future, or I can shatter your present. Every law you know is subservient to the Nexus Core. You are not players, you are code dependencies."
Tanjiro finally stood up, gripping his blade. His body was trembling, not with fear, but with righteous fury.
"I will not be a tool for your cruelty! I will fight you until my last breath, even if it means my world falls!"
The Arbiter laughed—a sound like glass breaking. "Noble, but foolish, Demon Slayer. Your will is irrelevant. Your sword, which slices the very concept of Demons, is powerless against the Meta-Concept of this space. You saw it: your blow did nothing."
The Arbiter projected a new hologram. It showed a small, terrified girl running through the streets of an unknown city.
"If you refuse, I will start small. This little girl is from the Dandadan universe. She is currently safe. Refuse my proposal, and I will ensure the next Titan that breaches the wall finds her. Do you wish to condemn a child you don't even know, Demon Slayer?"
Tanjiro recoiled as if struck. The Arbiter was not threatening their worlds immediately; he was leveraging their core moral principles against them, one innocent life at a time.
Gojo sighed, running a hand through his hair. He looked at Jin-Woo, then at Saitama.
"We have no choice," Gojo said, the words tasting like ash. "If we refuse, we fail our worlds. If we accept, we become his tools."
"Then we accept," Jin-Woo stated, his eyes now cold and determined. "But we change the rules of the acceptance. We do not work for him. We infiltrate his system. We become his Architects to learn the structure of the Nexus Core, and then we tear it down."
Jin-Woo looked at the terrifying Obsidian Door—the portal to their next, unknown mission.
"He wants us to conquer worlds? Fine. We will conquer them on our terms. We will use his power to protect the innocent of those worlds while we search for the weakness in his command structure."
Saitama, after a long silence, finally spoke, his voice low and serious. "I'll do it. I hate chores, but I hate this feeling more. If fighting this guy is a chore, I'll finish it quickly."
Malak's voice returned, now sounding completely triumphant.
"An intelligent decision. Welcome to the team, Architects. Your new mandate is clear: Conquer or Collapse. You no longer chase Tangles; you enforce my Universal Integration plan."
He focused his attention on Tanjiro. "Architect Tanjiro. You now know the cost of failure, and the price of betrayal. Next time, choose the winning side of the narrative."
The Arbiter projected a single, clean image of their next mission target.
"Your next assignment: The World of Grand Line. A reality defined by Absolute Freedom. You must locate the Anchor Point and destabilize its concept by introducing Absolute Law. Begin immediately."
The Obsidian Door roared open, and a blast of salty air, gunpowder, and the smell of high-adventure freedom rushed into the sterile white void.
The Nexus Seven—now the Architects of Moral Compromise—stepped through the door, their identities changed, their purpose corrupted, but their ultimate goal of survival and revenge set in stone.
