Three days had passed since the incident in the forest.
Anos moved through his father's field with the same calm he had maintained every morning since then — tool in hand, the sun at his back, the smell of turned earth familiar now in a way it had not been at first. He had decided, without much deliberation, that playing the role of Ren Nishimura was worth his while. Not because he feared what would happen if he abandoned it, but because this world was new, and a quiet life on its periphery offered a better vantage point than drawing attention to himself immediately.
Besides, his father talked while he worked. And people who talked tended to reveal more than they intended.
What the young man from the forest had already revealed, however, was more than enough to occupy his thoughts.
He had read the boy's memories before letting him go — a reflex as natural as breathing, as inconsequential to Anos as glancing at an open book. What he found was a surprisingly coherent picture of this world's conflict: a war between humans and demons that, over generations, had solidified into something with its own structure and language. Demon slayers. Breathing techniques. Hierarchies. An organization that called itself the Demon Slayer Corps, which trained its members from childhood to compensate with skill and willpower for what they lacked in raw power.
At the top of that organization stood nine individuals whom the boy's memories referred to as Pillars — the strongest active slayers, each a master of their own breathing style, each capable of killing what ordinary hunters could not.
And somewhere above all of them, an enemy who had started this war. A demon who had turned others into demons. A progenitor who had been directing this particular conflict for longer than any living human could remember.
Interesting, Anos thought, driving his tool into the earth with practiced ease. A demon who creates others. That requires a specific mechanism — not mere power, but a method of propagation. I wonder whether he understands what he has built, or simply that he can build it.
The young man's memories contained no direct information about the upper ranks of the Twelve Kizuki — only an indirect dread of them, the kind that accumulates in an organization through stories of missions that do not end well. But what Anos had deduced was sufficient. A hierarchy. A progenitor at its apex. And a group of human warriors who had spent generations searching for a way to kill something they could not reliably harm.
He had seen that architecture before.
He did not yet know whether it interested him enough to involve himself — but he was prepared to find out.
"Father," Anos said, setting his tool down carefully. "I am going to check on Mother."
Tetsuya looked up from where he was crouching over a stubborn root, wiping his forehead with the back of his hand. "Already? It's barely past dawn..." He caught Anos's expression and decided not to press. "All right, all right. Tell her I'll be back late."
"I will."
Anos withdrew from the field.
Once the house was out of his father's line of sight, he spoke a single word quietly — Gatom — and stepped sideways through space, reappearing on the path that ran along the edge of the village. He stood still for a moment, eyes half-closed, reading the surrounding area.
There it was.
A human presence, moving toward the village from the south at a pace that suggested training and purpose. The aura was controlled — deliberately compressed, the way skilled warriors learned to contain themselves — but to Anos, the compression was simply another signal. He could read its shape clearly: disciplined, powerful by human standards, and carrying that specific quality of focused intent that distinguished someone on a mission from someone merely passing through.
The Pillar, he concluded. Or someone sent on their behalf. Either way, the letter reached its destination.
He considered his options with the same calm he applied to everything else. The simplest approach would be to wait where he was and let the encounter unfold on its own. The more interesting approach—
He turned and walked back inside.
"Mother, I am home."
Aiko emerged from the back room, her expression shifting from mild surprise to something warmer. She had a way of looking at him — at Ren — as though his mere presence resolved something in her. Anos had noticed it on the first day and catalogued it as a defining trait of this woman.
"Back already? Is your father with you?"
"He will be late tonight." Anos settled at the low table beside the window with the ease of someone in no particular hurry. "He said not to wait up."
Aiko made a sound that conveyed decades of mild exasperation with Tetsuya Nishimura, then moved to the stove and began working with a pot that Anos understood, through Ren's memories, to be the beginning of dinner preparations. As she cooked, she talked — about the Harada family, two villages over, and their dispute with a merchant; about the unusually dry weather; about a neighbor's daughter who had apparently done something worth commenting on at length.
Anos listened. He responded at appropriate intervals. And with a thread of attention extended like a long finger, he tracked the approaching presence as it reached the village, paused at its edge — probably to ask for directions — then moved again, slower now, searching.
She is being careful, he noted. Good instincts. She does not know what she is walking into.
When the presence reached the street, Anos rose from the table.
"I need some air," he said.
Aiko glanced over her shoulder. "Dinner will be ready soon."
"I won't be long."
He stepped out of the house and into the evening light.

This time, he did not teleport.
He walked — because walking allowed him to observe, and because arriving at a meeting point naturally was more useful than arriving ostentatiously. He had learned, across the centuries of his first life, that the most effective way to unsettle someone with power was to appear entirely indifferent to their presence.
He was still turning over the peculiarities of this world when he rounded a corner at the edge of the forest and nearly crossed paths with a black crow that banked sharply overhead, heading south.
He watched it go.
A messenger, he thought. How convenient.
──────────────────────────────────────────
Three hours earlier and sixty-four kilometers to the south, the forest held a different kind of silence.
The kind that preceded violence.
The demon moved through the undergrowth with the particular confidence of something that had not encountered meaningful resistance in a long time. It was large — larger than the one Anos had destroyed three nights prior — wide-bodied and asymmetrical, with arms that ended in claws like bent iron and eyes that caught moonlight and held it in a way human eyes could not. A Lower Moon, though it wore that rank with the arrogance of something that had forgotten what lived above it.
It had been preying on three villages in this area for nearly a month.
Until tonight, it had not encountered anyone who gave it pause.
The young woman stepped out of the shadow of a cedar tree, and the demon stopped.
She was not what it had expected. Small, composed, dark hair falling to her waist with two shorter strands framing a face whose expression the demon could not immediately read — calm, almost warm, with a faint curve at the corner of her lips that was neither a smile nor resignation. Her pale violet eyes moved across its form with the unhurried, methodical focus of a craftsperson examining a problem.
The demon decided, as things that had survived a long time by correctly identifying threats tended to decide, that this one was dangerous.
It lunged anyway.
"You think that little sword will save you, human?" It bared its fangs as it moved, filling the air with the wet-iron smell of its breath. "You're just another weak hunter."
The young woman tilted her head.
"Weak?" she asked quietly, her hand finding the hilt of her katana. "Perhaps. But I've noticed that demons who say that tend to run out of time to reconsider."
She drew.
The demon's attack was fast — genuinely fast, the kind of speed that had killed eleven slayers before this one — but the young woman had already moved. Not away, but through. Her body rotated inside the arc of the attack with the fluidity and economy of someone who had rehearsed that particular geometry ten thousand times, and her sword came with her, tracing an arc that looked almost gentle until it wasn't.
"Flower Breathing, Third Form: Whirling Peach."
The katana sang through the air in a perfect spiral. The demon lurched back with a sound closer to surprise than pain, its claws raking the empty space where she had been half a second before. It turned, and she was already repositioning — breathing steady, expression unchanged.
The demon's eyes narrowed.
It attacked three more times in rapid succession, each strike faster than the last, abandoning the contemptuous rhythm of its opening and applying genuine force. The young woman gave ground when she had to, held it when she could, and her sword never stopped moving — not cutting, but guiding, redirecting, finding the precise angles where human technique could redirect a demon's force rather than oppose it.
When it finally overextended on a lunge, she was waiting.
"Flower Breathing, Fourth Form — Crimson Flower Garment."
The blade moved in a single clean line across the demon's neck.
The creature did not scream. It simply stopped mid-motion, swayed, and began to dissolve — slowly at first, then all at once, its body breaking apart into the familiar grey ash that drifted sideways in the night wind and was gone.
The young woman stood where it had been, lowered her sword, and exhaled once. A long, slow breath.
"Lower Moon," she said to herself, cleaning her blade with a practiced motion. She regarded the ash on the ground for a moment, then looked up at the sky. "They're growing bolder."
Her name was Kanae Kocho.
She was eighteen years old, the current Flower Pillar of the Demon Slayer Corps, and one of the most technically skilled swordswoman alive. She was also, according to most of her peers, an optimist to a degree that bordered on professionally inconvenient.
Kanae believed that demons and humans could coexist.
Not all of them — she was not naive about what most demons had become. But the belief that it was possible, even for some, even in a future her generation might not live to see, was the engine that drove her. It was also the reason she had never fully surrendered to the framework that governed most of her contemporaries: that demons were a category, not individuals, and that the only appropriate response to that category was extinction.
She understood where that perspective came from. She had watched it form in people she loved, people who had seen the same things she had. A demon had killed her parents when she was still a child, and the slayer who had saved her and her sister had been neither kind nor idealistic about the world. He had been right. Nearly everything he had told her was true.
But Kanae was not like most people.
She sheathed her sword and turned south toward home, and she was already running — the long, tireless stride of a Pillar covering ground — when she heard wings above her.
A black crow descended from the dark sky and landed on her outstretched arm with the ease of long practice. Without breaking stride, she caught the small scroll tied to its leg and opened it against her palm as she ran.
To the esteemed Pillar Kocho-sama…
She slowed.
Read it once. Then again.
The details the young slayer had described were extraordinary. Not the power itself — she had encountered beings of extraordinary power before. What gave her pause was everything else: the ease with which he carried himself, the genuine curiosity about a world he seemed to be discovering for the first time, the way he spoke of demons as though they were a phenomenon to be understood rather than an enemy to be destroyed.
And the name he had given.
Anos Voldigoad. The Demon King of Tyranny.
She did not know the name. But she knew what those words meant, if they were true. And something in the way the slayer had written about him — haltingly, reaching for language that did not quite fit — suggested that whatever he had witnessed, he had not found the right words to describe it.
Kanae folded the scroll carefully and tucked it away.
She needed to write to Oyakata-sama. She needed to see Shinobu first. And somewhere to the north, apparently, something without precedent was waiting for her.
She picked up her pace and ran toward home, the forest falling away on either side, the moon ahead of her rising.
