Meruem noticed the second disappearance at dawn.
This time, Komugi was asleep.
There was no effort to blame. No attempt to stand, no conversation about Whale Island, no visible change in her breathing. She lay beneath the inn's heavy blanket while the first grey light entered through the shutters, and for less than the duration of a heartbeat, the aura Meruem had been monitoring throughout the night ceased to exist within his perception.
Then it returned.
Not gradually.
One instant, nothing.
The next, Komugi was there again exactly as before.
Meruem remained beside the bed, perfectly still.
He had learned long ago that surprise wasted information. When something unexpected occurred in battle, the first task was not to react but to preserve what had happened before memory contaminated observation with interpretation.
Her breathing had not changed.
Pulse—stable, from what his hearing could determine.
Body temperature—no visible reaction.
No hostile aura nearby.
His own output had remained suppressed.
Mitu slept in the adjoining room.
Komugi had not consciously entered Zetsu. Of that he was almost certain. Zetsu closed the aura nodes and reduced leakage from the body; it did not make a person's existence disappear from a sufficiently sensitive observer as though the aura had been removed from the equation entirely.
And Komugi had never possessed this level of control.
Meruem waited.
Five minutes.
Nothing.
Ten.
Still nothing.
By the twentieth minute he had constructed seven possible explanations and rejected five.
The remaining two were both unsatisfactory.
Either his perception had failed—
unlikely.
Or something inside Komugi was changing in a way none of them understood.
More likely.
He disliked that answer.
Behind him, the door opened without warning.
Mitu entered carrying a cup of hot water and stopped when she saw his face.
"You felt it."
Not a question.
Meruem looked at her.
"You did as well?"
"No."
She placed the cup down.
"But you have the same expression you had last night."
"I do not have an expression."
"You have several. Most are unpleasant."
She approached the bed and checked Komugi without waking her, first conventionally, then with the faintest trace of Death Judge.
Meruem watched.
"Nothing abnormal now," she murmured.
"That does not answer what occurred."
"No."
"It happened while she slept."
That made Mitu pause.
Her fingers remained against Komugi's wrist.
"You are certain?"
"Yes."
"No movement?"
"None."
"Dreaming?"
"Impossible to determine."
Mitu considered that.
The inn creaked around them as the building warmed with sunrise. Somewhere downstairs, the owner dragged a wooden chair across the dining room. A rooster called from beyond the stable and received an irritated answer from another farther down the road.
Ordinary sounds.
Meruem had come to dislike how easily ordinary things could continue while something important happened beside them.
Mitu withdrew her hand.
"We stay."
"For how long?"
"Until I understand enough to know whether moving her is irresponsible."
"That could mean indefinitely."
"It could."
"No."
The old woman straightened.
Meruem lowered his voice before the argument could wake Komugi.
"Remaining here also has consequences. Your medicine supply is finite. The environment is uncontrolled. We are farther from your equipment than we were yesterday, and every day spent here delays the only treatment that might actually repair her condition."
Mitu's eye hardened. "And putting her back on the road immediately after her aura vanished twice would be what? Courage?"
"Calculation."
"No. Calculation requires variables you actually understand."
Meruem's tail moved once behind him.
Mitu noticed and continued anyway.
"You know what frightens physicians most?"
"I am not interested in what frightens physicians."
"That is why you should listen."
She gestured toward Komugi.
"Not symptoms. Patterns."
Meruem said nothing.
"A fever can be treated. A seizure can be observed. A wound can be measured. But when the rules of the condition keep changing, every treatment becomes a guess based on yesterday's disease."
Her hand rested against the foot of the bed.
"Yesterday, effort triggered something. Last night, it happened at rest. This morning, it happened in sleep. That progression matters."
Meruem looked at Komugi.
Mitu was right about one thing.
The board had changed again.
The cause could no longer be reduced to physical exertion.
"Then movement may not be the trigger."
"Correct."
"Which means stopping movement may accomplish nothing."
Mitu gave him a long look.
He continued.
"If it can occur while she lies motionless, remaining in this room does not remove the risk. It only removes our progress toward Whale Island."
The old woman's mouth tightened.
Neither had enough information to defeat the other's argument.
That itself was information.
Before Mitu could answer, Komugi spoke from beneath the blanket.
"Could you argue farther away?"
Her eyes remained closed.
Meruem looked down.
"You are awake."
"I became awake when someone started discussing whether my mysterious illness was frightening to physicians."
Mitu sighed. "You were supposed to sleep."
"I was doing very well until the two loudest quiet people I've ever met began whispering."
Meruem ignored the accusation.
"How do you feel?"
Komugi opened one eye. "Like someone who spent an entire day inside a carriage."
"Anything else?"
"No."
"Pressure behind the eyes?"
"No."
"Chest?"
"No."
"Spine?"
"No."
"Dizziness?"
"Only from the interrogation."
Mitu placed a hand over Komugi's wrist again.
Meruem watched the old woman's face.
Nothing.
Komugi looked between them. "It happened again, didn't it?"
Silence answered her.
Her humor faded.
"When?"
"While you were asleep," Meruem said.
She absorbed that without moving.
For the first time since Mitu had begun explaining the anomaly, Komugi looked genuinely unsettled.
Not afraid.
That would have been easier to identify.
Instead she glanced toward her own hands as though expecting them to provide evidence that they still belonged to her.
"I didn't feel anything."
"That is useful," Meruem said.
She looked up.
"How?"
"It means the phenomenon may not produce conscious symptoms."
"That sounds like the opposite of useful."
"It eliminates one assumption."
Komugi stared at him for a moment, then looked toward Mitu.
"Is he always like this when he's worried?"
Meruem's gaze hardened.
Mitu answered without hesitation. "Worse."
"I am not worried."
Neither woman responded.
He found their silence insulting.
---
By midmorning, the inn had filled with travelers.
The road outside carried produce carts, fishermen walking toward the river landing and two caravans heading east. Meruem remained near Komugi's room long enough to map every significant aura within the building.
Nine ordinary humans downstairs.
One weak Nen user near the stable, probably a traveler who had received basic training.
Edrin.
Mitu.
Komugi.
No one capable of concealing a presence from him well enough to create the phenomenon they had observed.
That possibility could be removed.
He left only after Mitu told him she intended to repeat several passive measurements and that his presence was contributing nothing.
Meruem interpreted this as an unnecessary insult.
He went outside anyway.
The river lay beyond the reeds behind the mill, broader here than he had realized from the road. Barges moved downstream at a pace he initially considered absurdly slow. Their long, shallow hulls carried barrels, timber, sacks of grain and sometimes passengers beneath canvas shelters built over the center deck.
Meruem watched one pass.
No wheels.
Minimal vertical movement.
Constant speed.
The current performed much of the work.
He looked upstream.
Another barge approached a wooden landing roughly five hundred meters away.
His attention sharpened.
The river road had been chosen because it reduced physical stress.
But they had continued thinking in terms of roads.
Why?
Because the carriage was already available.
An existing solution had constrained the next decision.
Meruem disliked realizing it.
He crossed the distance to the landing.
Edrin was there.
Naturally.
The merchant stood beside an overweight man in a brown coat, arguing over the price of transporting several crates downstream. He noticed Meruem approaching and immediately looked suspicious.
"What?"
Meruem glanced at the moored barge.
"How much movement does that vessel produce?"
Edrin blinked.
The bargeman answered instead. "Less than your carriage unless the river turns rough."
"When does that occur?"
"Not this season. Maybe near Namar if the north wind picks up."
"How long to Namar?"
"By current? Six hours. Eight if we stop at the locks."
Meruem calculated.
The carriage route required nearly the same travel period today, with two mandatory medical stops.
The barge offered slower absolute speed but fewer shocks, more room for Komugi to lie flat, and no horse whose condition could deteriorate.
"Can passengers remain aboard at the locks?"
The bargeman shrugged. "If they pay."
"How many Nen users travel this route?"
The man's expression changed slightly.
He possessed no Nen himself, but he knew enough to recognize the word.
"Hunters sometimes. Bodyguards. Same as any trade route."
"How many today?"
"How would I know?"
Edrin stepped between them before the conversation became less productive.
"He means whether you've taken any strange passengers recently."
The bargeman scratched his jaw. "Two Hunters three days ago. None since."
Meruem looked at Edrin.
"We use the river."
Edrin slowly smiled.
"What?"
"I was going to suggest that yesterday."
"You did not."
"You were inspecting wheel alignment."
"That does not prevent speech."
"No, but I've developed survival instincts."
Meruem ignored him and returned toward the inn.
For the first time that morning, the position had improved.
Not solved.
Improved.
There was a difference.
---
Mitu rejected the idea immediately.
Then she spent twelve minutes failing to find a medical reason to reject it.
That distinction eventually irritated her enough to accept.
"A barge gives me more space," she admitted while packing the medicine case again. "She can remain lying down. Less vibration."
"And if the phenomenon occurs?"
"We stop at the next landing."
"Not sufficient."
"Nothing is sufficient."
Meruem did not answer.
Mitu looked toward him.
He understood what she meant.
That sentence no longer angered him as much as it had twenty-four hours earlier.
Komugi, meanwhile, was focused on a different problem.
"I want to walk to the river."
"No," Meruem said.
Mitu did not even look up from the medicine case. "Absolutely not."
Komugi folded her arms.
"I didn't ask to walk eight kilometers. It's right there."
"Five hundred and forty meters," Meruem corrected.
She stared at him.
"You measured it?"
"Yes."
"That somehow makes your answer more annoying."
Meruem lifted the travel bag.
"You will be carried."
"I can walk a little."
"You demonstrated four seconds."
"That was yesterday."
"And today your aura disappeared while you were unconscious."
"That doesn't mean my legs disappeared."
Meruem stopped.
There were moments when Komugi's arguments were strategically sophisticated.
This was not one of them.
"No."
She looked toward Mitu for support.
The old woman remained very interested in organizing bottles.
Betrayed, Komugi sighed.
"Fine."
Meruem stepped toward her.
Then she raised one hand.
"But not the whole way."
He paused.
Komugi looked at the floor.
"I want to try."
Mitu finally turned.
"No test."
"Not a test."
"That distinction exists only in your head."
Komugi considered the accusation before answering. "Then let me stand for one second. If anything changes, he carries me."
Meruem almost refused.
Automatically.
Then he stopped.
Komugi had spent the previous day inside a carriage. This morning she had been examined repeatedly, discussed as though her body were a problem belonging to other people, and told once again that her own perception could not reliably warn them when something went wrong.
Her request was irrational if the objective was pure risk minimization.
But human behavior did not operate on pure risk minimization.
He had understood that abstractly.
It was more difficult to account for when the risk was hers.
Mitu watched him.
Apparently the decision had become his.
Unfortunate.
Meruem examined the board.
Standing was dangerous.
Total refusal produced another cost—one he could not quantify as easily.
Agency.
Komugi's willingness to report symptoms.
Trust in their decisions.
Her tendency to hide weakness increased when she felt controlled.
That was not speculation. He had observed it repeatedly.
"One second," he said.
Komugi's head lifted.
Mitu frowned.
"Meruem—"
"He will be in contact with her the entire time," he continued. "No step unless you confirm stable aura."
Mitu studied him.
Then Komugi.
"One."
Komugi smiled.
"That's all I asked."
Meruem did not believe her.
He placed one hand beneath her arm and another lightly behind her back.
Komugi shifted toward the edge of the bed.
Her feet touched the wooden floor.
Mitu placed two fingers against her wrist.
"Stable."
Komugi pushed upward.
Meruem took nearly all her weight before she could notice.
She stood.
One second.
Nothing happened.
Mitu watched her aura.
"Enough."
Komugi remained upright for another fraction of a second.
Meruem lifted her immediately.
"That exceeded the agreement."
"By less than a second."
"The amount is irrelevant."
"It seems extremely relevant when we're measuring seconds."
He carried her through the inn.
She did not protest again.
Outside, morning sunlight had spread across the road. Travelers passed them without interest. Edrin was already ahead with the baggage.
Komugi looked toward the river.
"I want to see it."
"You can see it from where you are."
"You know what I mean."
Meruem did.
At the edge of the reeds, he put her down.
Not entirely.
His arm remained around her waist, carrying enough of her weight that the difference between standing and being held had become mostly conceptual.
Komugi noticed.
She said nothing.
They moved.
One step.
Her aura remained stable.
A second.
Meruem's own pace would ordinarily have covered the distance in an instant.
He shortened it.
Third step.
Komugi's breathing remained steady.
Mitu followed closely behind them.
Fourth.
No reversal.
Fifth.
Komugi looked toward the water instead of at her feet.
Meruem adjusted again.
Slower.
It was an absurd form of movement.
A being capable of crossing a battlefield before ordinary humans registered his departure was taking steps barely longer than Komugi's foot.
He could feel every unnecessary second.
The barge waiting.
Whale Island beyond Namar.
Folklore beyond the known world.
Time continued moving whether they did or not.
Yet he did not accelerate.
Komugi's sixth step was less stable.
Meruem felt it before she did.
He lifted her.
She started to object, then noticed Mitu's expression and stopped.
"How many?" she asked.
"Six," Meruem replied.
Her smile was small.
"That beats four."
"It is not a competition."
"That's what people who are losing say."
Meruem looked down at her.
Then, despite himself, toward the road behind them.
Six steps.
Insignificant.
They had moved less than four meters.
Yet the calculation had changed.
Not because Komugi had become stronger.
Because he had matched her pace.
Meruem carried her the rest of the way.
The barge departed shortly before noon.
From beneath its canvas shelter, Komugi watched the riverbanks slide past with almost no vibration beneath her. Mitu sat nearby, one hand never far from the medicine case. Edrin had already begun arguing with a deckhand about the price of lunch.
Meruem stood near the bow.
The river did not move quickly.
It curved around fields, villages and low wooded hills, surrendering the shortest route whenever the terrain demanded it.
Yet it never stopped moving toward the sea.
Meruem watched the current for a long time.
For most of his life, slowness had meant weakness.
Today he began to understand another possibility.
Sometimes moving slowly was not the failure to advance.
Sometimes it was the only speed at which everyone arrived.
Ahead, beyond the next bend, Namar waited.
And for the first time since leaving Mitu's mountain house, Whale Island felt less like an idea on an old map.
It felt reachable.
