The battle for Tachikawa Base had devolved into a desperate, grinding war of attrition.
Soshiro Hoshina was a phantom of death moving across the top of the wall, his twin blades a constant, shimmering blur. For every one of the obsidian monsters he cut down, three more seemed to crawl over the edge. His stamina, honed to a superhuman degree, was beginning to flag. His breath came in ragged gasps.
Kikoru Shinomiya was a golden comet of destruction on the lower parapets, her axe carving huge swaths through the enemy ranks. But even she was being overwhelmed. The sheer number of targets was staggering. Her suit's energy reserves were dropping at an alarming rate.
Kafka, his ribs screaming in protest, huddled behind a barricade with Reno, taking potshots and trying not to die. He could see it clearly: they were losing. The Kaiju were too numerous, too coordinated. The Defense Force's line was bending, about to break.
Then, the world went quiet.
It wasn't a sudden absence of sound. The explosions still roared, the shrieks still echoed. But a profound, pressure-filled silence fell over the souls of everyone on the battlefield. It was an aura, a palpable presence that washed over them, so immense and so absolute that it dwarfed the chaos of the fight.
Every single one of the new, blade-armed Kaiju froze mid-stride.
Their animalistic, tactical minds were suddenly wiped clean, replaced by a single, overwhelming, primordial instinct: FEAR. Not the fear of a predator or a superior foe. This was the fear a bacterium might feel in the presence of the sun. The fear of a concept confronting its own annihilation.
Every soldier on the wall felt it too. It was a cold wave that washed through their bones, making their hair stand on end and their trigger fingers tremble.
Kikoru froze, her axe halfway through a swing, her heart suddenly pounding in her chest for a reason that had nothing to do with combat. "What... what is this pressure?!"
Hoshina stopped, landing atop a battlement. His tactical mind, for the third time, simply shut down. He knew this feeling. It was the feeling of standing in the presence of a conclusion. It was the feeling of gravity deciding to speak.
In the center of the base's main courtyard, a figure now stood where a moment before there had been nothing.
He had landed without a sound, without a shockwave, without any disturbance at all. He just... was.
Saitama stood there, still rubbing the sleep from his eyes, clad in his simple yellow suit and white cape. He looked around at the chaos, the burning vehicles, the dead monsters, the terrified soldiers.
And he let out a deep, profoundly disappointed sigh.
The sigh was not loud. But for every being on that battlefield, it was the only thing they could hear. It was a sound that carried the weight of infinite boredom and cosmic annoyance. It was the sigh of a god who had been woken up from a nap for this.
One of the obsidian Kaiju, its programming overriding its primal fear for a split second, screeched and leaped at him from a nearby roof. It was a blur of black blades, an avatar of speed and death.
Saitama didn't even turn his head. He just flicked his wrist backwards, a lazy, dismissive gesture, like shooing a fly.
flick.
The Kaiju, moving at supersonic speeds, exploded.
It didn't just get hit. It detonated into a fine, black mist. There was no impact, no sound. One moment, a monster. The next, a cloud of vapor that silently dissipated in the breeze.
The godly action had been performed. And it was so casual, so effortless, that it was more terrifying than any city-destroying roar.
Silence. This time, a true, ringing silence fell as every single combatant, human and Kaiju alike, stopped to stare.
Saitama finally seemed to notice the army of monsters frozen all around him. He looked at one, then another. "So you're the ones making all the noise," he said to no one in particular. His voice was quiet, but it seemed to echo in everyone's minds.
"Could you please... go home?"
The Kaiju, creatures born of strategic malice and programmed aggression, responded as one.
They turned and fled.
It was a complete, instinctual rout. They scrambled over each other, clawing their way back over the walls, desperate to escape the courtyard, the base, the city. To escape the sheer, soul-crushing pressure of his existence. They weren't retreating. They were running for their very lives from something their minds couldn't even begin to process.
The entire invading army, a force that had brought the elite Tachikawa Base to its knees, was broken and sent fleeing by a single sigh and a flick of the wrist.
Saitama watched them go, scratching the back of his bald head. "Huh. Well, that was easy."
He turned, planning to go back home to his interrupted nap.
And found himself facing the assembled, stunned, and terrified remnants of the Japan Defense Force.
Hundreds of soldiers stood on the walls, their weapons still raised, all pointed at the lone figure in the courtyard. They had just witnessed a miracle, a victory so absolute and effortless it defied comprehension. And now the source of that miracle was standing in the middle of their base.
Hoshina was the first to move. He leaped from the wall, landing silently in the courtyard a respectful twenty paces from Saitama. His blades were sheathed. This was not a confrontation. He was a scholar who had just stumbled upon a living god.
Kikoru landed beside him a moment later, her axe held loosely at her side. Her usual arrogance was gone, replaced by a wide-eyed, disbelieving awe.
Kafka and Reno watched from the parapet, Kafka's cracked ribs forgotten. He had seen this power before, but to witness it on this scale, to feel that soul-crushing aura firsthand... it was different. It recalibrated your entire understanding of the universe.
Saitama looked at the two officers in front of him. "Hey," he said. "Are you in charge here? Can you tell your neighbors to keep it down? Some of us are trying to sleep."
The request was so mundane, so absurdly domestic in the face of the carnage around them, that Hoshina was momentarily stunned into silence. He had prepared for a hundred possible conversations with this entity. A debate on morality. A demand for tribute. A declaration of war. He had not prepared for a noise complaint.
It was in this moment that Genos landed softly beside Saitama, a whirlwind of gleaming metal and quiet efficiency.
"Master," he said, producing a notepad. "I have concluded my preliminary analysis. The enemy forces were a new biomechanical model, suggesting an intelligent guiding hand. Your intervention lasted approximately 37 seconds from arrival to the enemy's complete rout. You utilized 0.0001% of your estimated power. It was, as always, a flawless victory."
He turned to the stunned Hoshina and Kikoru. "My master is tired," he announced, as if speaking to a pair of errant children. "He will now be returning home. Please ensure there are no further disturbances."
Saitama just yawned. "Yeah, what he said. See ya."
He turned his back on the assembled military might of the Japan Defense Force and began to casually walk away, as if leaving a neighbor's barbecue.
And nobody dared to stop him.
Every soldier watched as the two figures walked across the courtyard, their steps echoing in the sudden, profound silence of the night. The Silent God had come, had solved their unsolvable problem with the effort it took to sigh, and was now leaving, his only complaint being the noise. The sheer, goosebump-inducing gap between his power and his concerns was a terrifying, addictive mystery that would haunt every person who witnessed it for the rest of their lives.
