The signal arrived in Genos's mind without warning.
He'd been sitting in the guest room, processing the morning—the dinner, the arrangements, the sheer density of things that had needed updating in his mental logs—when something cut through his passive reception like a frequency he recognized without being able to name it. He came fully alert immediately, optical sensors scanning the room, energy detectors running their grid. Nothing. No external source.
The signal seemed to find this information interesting. It bypassed his firewall—not forcefully, but smoothly, the way something designed for this exact entry point would—and resolved itself into a familiar voice.
"Genos. Time for training."
Genos set down the paper fan he'd been using to do nothing in particular and was upright before the voice finished. "Is that Jordan-san?"
"It's me." Jordan's voice carried the ease of someone already walking. "When you're ready, head to the back hill and find Master Bang."
"Understood. I'll be there immediately."
He was already moving.
By the time Jordan crossed into the guest room courtyard, Genos was a dwindling orange-red afterburner trail vanishing over the rooftop, the heat signature of his jets diffusing into the morning air.
Jordan watched this and exhaled the way a person exhales when something is genuinely not surprising.
Full energy. Every time.
He walked into the guest room.
Saitama was sleeping with the total commitment of someone who had left his body behind and had no immediate plans to return to it. Sprawled sideways across the bedding, one arm trailing, mouth slightly open. Occasional snot bubble. A sequence of small sounds that were technically snoring but had achieved a kind of rhythm that was almost peaceful.
Just looking at him made Jordan want to lie down.
He was still weighing whether this was a reasonable idea when F-boy stepped out of his chest.
The humanoid Stand materialized in the quiet room—pale purple, blue flames at the edges, the skirt armor of layered fantasy cards shifting slightly as he found his footing. He glanced at Saitama with the dispassionate assessment of someone clocking a resource, then peeled away a card-plate from his skirt armor. The plate dissolved into a white-bordered N-rank card in his hand and he got to work.
What followed looked, from the outside, like a man standing next to someone sleeping and catching things that weren't there. But Jordan watched the fragments accumulate—card-shaped pieces of luminous energy drifting off Saitama's general vicinity like snow off a heated surface, drawn toward F-boy's outstretched hand, piling up with the patient abundance of a farm that had been productive all season.
Hair. Every strand of it. Farewell. We'll miss you.
The harvest complete, F-boy straightened. Then, without the transition of doing anything that looked like preparation, he produced something from the folds of his card armor and held it out.
A card. Pale gold at the border.
Jordan took it automatically. Turned it over once.
Inside the pale gold frame: a figure in red robes standing at a mountain peak above white clouds, one hand resting on a sword hilt, a wooden toothpick at the corner of his mouth, expression cold and certain. Every element of the image radiated the composed arrogance of someone who had spent decades earning the right to look exactly like that.
F-boy nodded at Jordan's unasked question.
Jordan read the card.
[Fantasy Card: The Ultimate Sword Master] Type: Ability Card • Rarity: SSR (Gold)
The swordsmanship talent of Kamikaze—Atomic Samurai—leader of the Sword Saint Association. In the One-Punch Man world, the pinnacle of the blade.
Grandmaster of Kendo: Mastery of any sword or bladed weapon; techniques and ultimate moves accessible on first contact
Shatter in One Hit: Naturally superhuman hand speed; unleashes sword techniques capable of pulverizing at the atomic level
Slay Everything: Slashing attacks infused with an obsessive conviction that has reached the level of cutting through anything
Water Mirror: Total mental stillness; the meditative state that allows the legendary sword to be heard and wielded
Jordan looked at the card for a long moment.
Then: "On the surface, picking a fight. In practice, leaving cards behind." He turned it over in his fingers. "Is that the mindset of a man who pretends to hate losing?"
He thought of a certain old man—considerably longer acquaintance, considerably more accumulated sparring sessions—who had yet to produce a complete suite of martial arts techniques despite ample opportunity.
Stingy, he thought at Bang's general direction. Incredibly, historically stingy.
Somewhere on the back hill, Bang sneezed.
Two SSR cards in under two days had done something decisive to Jordan's energy levels: specifically, it had returned them. The urge to take a nap had evaporated entirely. He looked at Saitama's still-sleeping form, did a quick internal calculation, and activated the Herrscher's authority.
The connection to the imaginary space opened—or rather, connected him to a different one.
The previous space had served its purpose. After the sparring session, it had been ended by a punch thrown out of what could only be described as genuine curiosity about what would happen. What had happened was that the environment had stopped existing, dispersing into the spacetime current like smoke. Jordan did not feel strongly about this.
He stepped through.
The new world arrived in sound first.
Massive. Oceanic. The crash of something enormous and continuous—waves, or what moved the way waves moved but was built from different material. Jordan registered that he was falling before he registered where to.
His spatial authority activated on its own. It found his feet, located something close enough to "down" to work with, and steadied him in midair several hundred meters above the surface.
He looked.
The world below was the color of deep water and active sky at once—a shade that didn't quite exist in normal physics. Energy moved across it in rolling formations that behaved like ocean waves but were made of something other than water. From horizon to horizon, no land. Just the churning quantum sea, its surface lit from within by currents of something prismatic that crashed and reformed without ever settling.
Jordan looked at it for a moment with the expression of someone being told very bad news.
"Even the air I need to stand on requires reclamation from the sea," he said. "I'm going to cry."
He put his feet down anyway.
Spatial authority solidified beneath him—not ground, but the abstracted concept of ground, something that would function in the same role. Then Honkai energy began to move. It gathered from the imaginary space around him, dense and inexhaustible from Sirin's reserves, and began to construct.
The first cube appeared—ten meters on each side, pale luminescent, dropped into the energy sea like a foundation block. It hit the surface and was hit back by a wave a hundred meters high that dissolved in the air without touching Jordan.
Then another cube. Another. Each one that reached the sea absorbed the Honkai energy Jordan was feeding into them and began to grow, pulling adjacent constructions toward itself, piecing together in the spaces between. What grew from the ocean floor was gradual and then suddenly not gradual—
A flat expanse emerged from the boundless sea. Roughly a kilometer square, solid underfoot, stable against the continuous siege of energy waves crashing against its edges from every direction without finding purchase. It sat on the surface like something that had always had the right to be there, which, under Herrscher's authority, it now did.
Jordan descended slowly as the island completed itself beneath him.
He landed.
The surface was solid. The waves broke against its edges and collapsed. Around him, the quantum sea continued its ancient motion, enormous and indifferent, and the island held.
He was ready.
Jordan took the pale gold SSR card and pressed it flat against his chest.
The card dissolved. Gold light fractured into fragments, then into something finer than fragments—something that felt like starlight moving inward rather than outward, passing through skin and bone without resistance, integrating.
And then the memories.
Not his, but stored in the card the way expertise stores itself in the body of someone who has done one thing for a lifetime. Swordsmanship. The specific texture of decades of daily practice—ten thousand swings become one hundred thousand become the point where the practice and the practitioner are no longer separable. The cold mornings on mountains. The sound of steel against steel in a thousand different conditions. The accumulated catalog of powerful opponents and the particular moments when technique and instinct unified and something happened that couldn't be taught directly, only passed on through the residue it left behind.
Atomic Samurai's lifetime of the blade, compressed and crystalline, downloaded directly.
Jordan stood on his island in the quantum sea and felt an overwhelming urge to cut something.
Unfortunately, the quantum sea had no volunteer targets.
One of the Herrschers could probably create life at will, he reflected. That would solve this particular inconvenience.
F-boy appeared.
The two of them looked at each other across the island's flat surface. Jordan nodded once.
F-boy's expression said: I know what you want. I have objections on principle. I am going to do it anyway.
He drew back his fist.
"Ora."
The punch landed against Jordan's left chest—not a combat technique but a precision movement, the fist drove inward and returned, and when it retracted it brought something with it: a pale yellow crystal, prismatic, faceted, radiating Honkai energy in the specific frequency of spatial dominion.
The Herrscher Core. Sirin's original form, before Jordan had convinced her that resistance was a poor use of her time. It sat in F-boy's purple hand, gem-bright, about the size of a closed fist, and pulsed with the patient energy of something that was waiting.
It would stay in this form as long as Jordan kept the Herrscher of the Void equipped. The day he chose to uninstall the card, the Core would reset itself to something closer to its original state. Until then: a gem, a Herrscher's condensed authority in miniature, fully claimed.
F-boy placed it on the island surface between them.
