Atem goes missing for a few minutes and Kaiba discovers what that costs him.
On the roof, with the afterlife refusing to answer, the argument stops being about untangling anything.
Kaiba offers the one solution he has left.
In the epilogue, the goddess explains why the gate never opened — and asks to be fired.
The light of the data ranged across the displays all looked dull somehow, and cold.
Working with his hands, Seto had noticed that the silence of the Atem standing beside him was heavier than usual.
Deep in that silence, he could feel the light of the sea that day still falling faintly.
As though only its residue were quietly breathing inside Atem. But it is not something that can ever be caught again, reason told him.
Purpose and theory were both far off now.
"…I'm going to rest a little."
Atem drew back his chair and stood. His voice was slightly drier than usual.
Seto nodded briefly and squared up his documents again.
Only the sound of pages rubbing together ran through the hushed room.
But mere minutes later, he noticed.
The presence that should have been there had slipped clean away.
Deep in his chest, something gave a faint jump.
Not returning. He cannot return. He will be back before long.
Understanding that, his body had stood up of its own accord.
He checked several corridor cameras.
Atem did not appear on any of the screens.
His breathing grew slightly shallow.
Where has he gone.
As he walked, Seto went on chasing a wrongness he could not explain even to himself.
More than the fact that Atem was nowhere in sight, something in his chest was creaking.
A kind of blank that would never ordinarily occur was spreading quietly.
Only his footsteps echoed in the corridor.
In the gaps between those echoes, he caught himself, for just an instant, trying to search out the sign of Atem's breathing.
Not here.
The fact was simple, and yet it was strangely sharp only in the moment it landed on the heart.
When he breathed out, his chest hurt.
Just as the light of that sea had become a residue and set Atem wavering, something inside himself went on wavering faintly as well.
What are you rushing for.
Reason whispered it coolly.
But the depths of his chest carried a faint heat, to a degree that made composure useless.
Halfway up the stairs, Seto stopped.
He drew one deep breath, and still could not wipe away the roughness at the back of his throat.
Atem cannot return.
That is fact, and unshakeable reality.
Then what is this, now.
A mental wrongness that should have been impossible: he might disappear.
It was not like him.
But the more he denied it, the thicker the stirring in his chest became.
Before him was the last door, the one leading to the roof.
The fingertips that touched it trembled faintly.
The instant he became aware of it, Seto clicked his tongue shortly and forced his breathing level.
Atem is beyond this.
There was no reason anywhere for the certainty, and yet his chest had already chosen that answer ahead of him.
The cold of the door came through his palm.
That difference in temperature reflected his own wavering without mercy.
Unless he opened it, he would not know.
Seto lowered his eyes quietly and held his breath for just an instant.
It was a short, quiet resistance, meant to hold back the selfish impatience deep in his chest.
And then, as though leaving his hesitation behind, he pushed the door open.
When he pushed the door open, the night wind stroked his cheek.
The temperature was low, and yet it was a strangely soft wind.
There, Atem was.
His back against the railing, looking slowly up at the sky.
The lights of the town flickered as distant, faint grains, and that light lit his profile palely.
The expression was fragile enough to collapse at a single breath, and beautiful.
"…I've been looking for you."
The short words were calm, but the impatience behind them was audible only to himself.
Atem turned and laughed a little.
"Sorry. I only wanted to feel the wind for a while."
A gentle voice. But mixed into that gentleness was a definite distance.
Seto lost his words in spite of himself, and gazed at that profile.
Taking the moonlight, Atem was like a bubble that would vanish if touched, and deep in Seto's chest, something creaked.
Logic and mission made no sense.
Only the cry of I do not want to lose this existence was beginning, clearly, to take a shape.
"Atem."
The voice calling the name was rough.
Atem moved his brows faintly and turned around.
"What is it?"
Seto drew breath and searched for words.
But before composure could close his mouth, his heart moved first.
"…Do not vanish on your own."
The night wind felt as though it had stopped dead.
Atem's eyes shook with surprise, and deep within them a soft light slowly kindled.
"I can't vanish. That's why I'm here, isn't it…?"
Seto did not answer, only kept his gaze from leaving those eyes.
That silence was more eloquent than anything.
Atem let out a soft breath.
Deep in his chest, something quietly began to sound.
A critical point lay ahead.
Both of them faintly sensed it.
"…I… am here now, aren't I…"
That one line changed the outline of the world.
The wind blew through again, and the stillness of night returned.
But nothing was the same any more.
At the words that had spilled from his own mouth, Atem's chest shook a beat late.
The instant he said here, he knew something inside him had given way.
He should have been stating nothing but the situation, and yet it came far too close to life.
The world goes quiet.
Seto does not move.
He is only looking at Atem.
From where the gaze touches, his heartbeat quickens.
Here — of all places, I do not want to be touched.
Reason announced the danger, and yet in the deep places of his chest a contrary voice whispered.
Touch me.
That whisper was heavier than the silence of the afterlife, and warmer than the wind of the living world.
Atem lowered his eyes.
He had not said it lightly.
They were words that spilled out as though he had been made to say them.
The instant he had said I am here, he dimly realised, he had already lost the right to knock at the gate of the Underworld.
One who can return does not speak this way.
The moment he finally admitted that fact, deep in his chest something creaked faintly.
——It aches.
I do not want to run.
Seto had not moved a single step, only gone on watching.
That gaze caught Atem's heart more strongly than words.
Why are you saying nothing.
The silence erased his escape routes one by one.
As though, instead of cornering him, it were making it impossible to go back.
The wind blew softly through and stirred Atem's hair.
The afterlife did not respond.
However he called, the gate only returned its quiet silence.
Seto's gaze traced that silence.
To run was no longer permitted.
Atem drew breath.
His chest was heavy, and hot.
Something that would not become words trembled in his throat.
Seto's blue eyes seemed to say—
Then come here.
—exactly that.
Atem let his gaze wander.
To look at Seto set his heart shaking.
To look away set his heartbeat clamouring.
Calm down. It's nothing. We only exchanged words.
He tried to think it, and his body would not obey.
The sensation of the soles of his feet not touching the ground.
He was standing, and yet somewhere he was sinking.
Seto's breathing resonated quietly.
That sound alone felt abnormally close.
Atem bit his lip.
He had not been touched by Seto, and still he was as unsettled as though he had.
In the instant that gaze took hold of his heart, Atem's world tilted slightly.
Seto slowly reached out a hand.
He did not touch.
But the temperature of the moment just before touching reached Atem all the same.
That temperature closed tight around the depths of his chest.
The instant Atem looked away, Seto stepped forward and, without hesitation, embraced him.
"…Kaiba…?"
Atem's body went stiff with surprise.
Seto said nothing, only wrapped that slender back firmly.
A distance at which each other's heartbeat carried.
After several seconds of silence, Seto's low voice fell.
"You no longer have to… untangle it."
Atem caught his breath.
"What…?"
Seto tightened his arms faintly.
As though to say he did not care if this were the last.
"As things stand, if taking me along when you return is the obstacle — then do not return."
That voice was neither logic nor strategy.
It was a truth spilled from deep in the chest, resembling a confession and resembling a wish alike.
Atem's eyes shook, and within Seto's arms he trembled faintly.
"…Even if you say that, I…"
Seto did not listen for the rest, and laid a hand against the back of Atem's head.
"However you struggle, this tangle will not disappear."
That tone was certainty itself.
Not an explanation, but the presentation of a fact.
"Why…"
Why do you say such a thing.
Why do you look at me with those eyes.
A trembling question. His eyes were faintly red.
Seto let out a short breath.
Not the sign of resignation, and not hesitation.
Only a breathing in which resolve alone seemed to carry a temperature.
Atem could do nothing but wait for the words that followed.
The option of fleeing had grown strangely distant.
The silence of the afterlife is heavy.
But Seto's silence was heavier still.
It fell, without question, deep into Atem's chest.
His breath stirred Atem's hair.
It was the slightest change in distance, and yet the density of the air changed.
Atem caught his breath.
Strength went into his shoulders, and his fingertips trembled faintly.
"…Why, you ask…?"
The low voice resonated like a blade cutting hesitation away.
Atem raised his face.
Seto's blue eyes were piercing him straight through.
That distance was telling him, instinctively, of danger.
He wanted to flee, and his feet would not move.
If he could have refused, he would have refused long ago.
He knew there was no longer any reason anywhere to refuse.
The afterlife does not answer.
It sends neither a signal to return nor a sign to wait — nothing at all.
Then, in this silence, where does he fall.
"Kaiba…?"
Merely calling the name set his throat trembling.
Somewhere in his consciousness, he was aware that the will to resist had begun to dissolve.
Seto steadied his breathing and declared it, with force.
"I will tangle."
Sound vanished from the world.
At that one line, Atem's chest drew tight.
It resonated somewhere beyond understanding, and yet as unmistakable truth.
Seto was no longer hesitating.
What he wanted was to live in the now together with Atem.
Atem lost his words, and within that chest his heart shook.
The tangle of souls rose up, past all logic.
But.
What crossed Atem's mind was the gate of the Underworld.
It did not show itself. Even so, only the fact that it did not answer remained, certain.
I must return, reason cried.
But from the instant he touched Seto's body heat, that voice had been receding.
Into his head came the days since he had come to America.
Seto's words, the arguments at night, the heat of the Duels.
The light of the sea, the smell of the wind, the sound of laughter.
A back that spoke of dreams.
And that, watching it, he had laughed himself.
Things he, being dead, should never have been able to hold.
——Being able to do what one wants to do
——Enjoying oneself to the fullest
——Coming to have memories
And then,
——Caring for someone
Every one of them was something no longer permitted to him, who was dead.
His chest was hot.
He was not being cornered.
He was being wanted.
That certainty breathed quietly in the depths of his heart.
If I am touched any further, I cannot go back.
He knew it, and could not look away.
Seto's fingertips stopped a hair's breadth from falling against Atem's cheek.
That distance was close enough to hurt.
In the silence, Seto's breathing deepened by one, and the world tilted quietly.
"What am I supposed to do…"
Before he had noticed it, he had found the world beautiful, and imagined a future that existed there.
Deep in his chest, a pulse strong enough to hurt.
Resignation, or joy. An emotion he could not tell apart overflowed.
"Do not be afraid."
Seto's low voice was dropped close beside him.
Not an order, and not an invitation.
Only a sound that seemed to wrap the wavering itself.
Being told not to be afraid made him more afraid, and still there was a part of him that wanted to cling to that voice.
——I ache to stay.
A voice sounded inside his head.
"No… I… can't return any more…"
As though enduring pain, Atem gripped Seto's shirt.
A faint tremor in his fingertips. His lips shook slightly, and deep in his chest something clenched tight.
The back of his nose hurt as though pierced, and heat gathered at the inner corners of his eyes.
Desperately, he held back a heart on the verge of collapse.
"…I am alive, now…"
The confession trembled, and dissolved softly into the stillness of the night.
What remained was only an inescapable present.
Seto touched the reddened rims of Atem's eyes, softly.
Deep in those blue eyes there was neither question nor refusal.
Only a quiet certainty, receiving the existence before him exactly as it was.
"That's right. You are alive."
At that voice something deep in his chest answered, and Atem's lips trembled faintly again.
Whether he was crying or trying to laugh, he did not know himself.
Only that inside his chest, something was unmistakably budding.
"…Because you are so… so alive. So vivid. …That is why I, before I knew it…"
Had begun to live.
Seto slowly put strength into the arms drawing him close.
He had never, from the beginning, had any intention of letting go.
Heartbeats touched, breathing tangled, temperatures overlapped.
Wearing a faint smile, Seto whispered.
"…So you tangled as well. …In my life."
Atem nodded slightly and rested his forehead against Seto's chest.
The world fell silent, and the whispering of reason was far away now.
I must return.
The instant that voice touched the warmth, it crumbled like sand and vanished.
He put his arms around him and buried his face in Seto's chest.
The sound of the heart resonating at his ear echoed, a beat late, deep into his own chest.
His face still buried against Seto's chest, Atem felt the life beating unmistakably inside himself as well.
This sound — I never want to forget it again.
He is alive.
Unmistakably, here.
"Kaiba… you're alive… you're so terribly alive… I can't return…"
The instant those words spilled out, Seto brought his cheek close and smiled.
"…You are alive. It is enough to stay here."
Within a warmth reason could not resist, the time of the two of them flowed quietly, and yet vividly.
The voice saying he ought to return to the afterlife was drowned out by the pounding in his chest.
Touching the vividness of being alive, their souls were tangling quietly, and unmistakably.
Surprise and confusion were both far away now; what remained was only each other's heartbeat and breathing.
"There is… no longer any need to return."
Seto's voice resonated low, certain, and gentle.
Receiving those words, Atem nodded faintly.
He understood that his heart and his body alike were already tangling into this moment.
Seto's lips touched Atem's forehead. Lightly, and yet a definite warmth.
"This is where you belong."
Not an order.
Not a wish, either.
As naturally as breathing, the distance closed.
Atem's eyes grew faintly wet.
Emotion that had come loose deep in his chest surged in like a wave.
Their lips touched.
I can be touched, I have a temperature, I am alive.
Reason no longer whispered anything.
In the stillness of the night, in a place that was neither the afterlife nor the world of the living, only each other's existence was certain.
It seemed that their tangled souls had, for the first time, overlapped completely.
Atem let out a small, trembling breath and let it be drawn into Seto's chest.
"……I am, alive……"
"That's right. You, and I both."
The night wrapped the two of them quietly, and densely.
Neither the laws of the Underworld nor the laws of the living world reached them, for this one span of time.
There was only the temperature of life.
The lingering trace of Seto's lips against his forehead became a faint tremor, filling Atem's chest.
That temperature belonged to none of the light of the afterlife, nor to any memory of the past.
Only the moment called now held a shape, pulsing.
The night wind stroked slowly between the two of them.
And in spite of it, the core of his body was strangely hot. So hot that wherever he was touched, he felt he might melt away.
Atem lifted his face from Seto's chest.
His eyes were faintly wet, and their colour was not a deep red but soft, like a jewel beginning to melt.
"…I think I must have… from the instant I touched your life, been drawn to you past all helping."
It was less a sentence than the shape of what he truly felt, leaked out from the very bottom of himself.
Seto's blue eyes wavered quietly, receiving those words as though confirming them one at a time.
"Atem."
Merely being called set his chest aching.
The resonance of the name struck his breastbone as though it had become proof of being one of the living.
Seto touched the rims of Atem's eyes and stroked them softly with his fingertips.
It was a gentle motion, and yet strangely it held a force impossible to resist.
"Dead, unable to return. Such things are of no consequence. You, here, touching my world — that is fact."
Atem held his breath.
Deep in his heart something trembled, answering the words he had wanted to hear.
"Kaiba…"
Something he had been holding down came loose deep in his chest.
Far heavier than the silence of the afterlife, a now with nowhere to escape pressed close.
Suddenly Seto took Atem's shoulders in his hands and brought their foreheads together.
A distance at which their breathing touched.
Close enough that even the sound of their hearts mingled.
"Live. At my side."
Those words were not an order, and not a wish; it was a clear tone that held out a future already chosen, exactly as it was.
Atem's throat trembled.
"……Am I allowed… to live…?"
The question that finally spilled out.
It was fragile, like a small child's, and yet it carried the resonance of something deeply wanted.
Seto answered that question without hesitation.
"From the instant you wished to live, it has already been permitted."
Atem's chest beat hard.
Hard enough to hurt, unmistakably.
"…I want… to live…"
The instant he murmured it, the strength nearly went out of his knees, and Atem clung to Seto's arm without thinking.
Seto caught and held that body at once.
The air of the night changed.
As though answering their choice, the moonlight came down a shade thicker.
Seto let out a light breath and whispered at Atem's ear.
"Live. From here on, I will be your witness."
Atem's eyes shook wide.
"That you live, that you waver, that you hesitate — all of it."
That voice resonated deeply in the stillness of the night and sank slowly to the very bottom of Atem's chest.
There was no escaping.
But it was not a binding.
It was a strange shackle of temperature, resembling release.
Atem answered in a trembling voice.
"A witness… I don't need such a…"
Seto smiled.
"You do. You need one."
Atem could not move, his breath still caught.
The world was changing shape at nothing more than the temperature of Seto's hand.
"There is no longer any need to return, and no reason anywhere to vanish."
Seto's whisper slowly painted over the stillness of the night rooftop.
And Atem quietly closed his eyes and nodded, unmistakably.
"…I will… live. With you… in this place."
Seto's expression eased faintly.
In that instant, the tangle between the two of them sank so deep that no one could ever undo it again.
Epilogue: As We Are, Tangled
The wind between the buildings broke off for a moment, and in its place a warm wind blew softly through.
Beneath the inorganic smell of the city, the faint trace of a dry desert bled through.
A layer of distant memory shook, and the presence of the Seto of long ago touched the world thinly.
Atem raised his face, and before him the goddess appeared out of nowhere.
Brown hair stirred, and long, narrow blue eyes narrowed in amusement.
"Well now. So it turned out that way after all."
The goddess narrowed her eyes, thoroughly entertained.
"Fufu. That's why you were turned away at the gate, then."
"…Turned away?"
The goddess's shoulders shook, mischief bleeding into the edges of her words.
"Yes. Because there's no possible way the you of right now could return, is there?"
He cannot return.
He does not want to return.
He wants to be here.
Atem glanced at Seto.
Seto received that glance quietly.
The change in his expression was slight, but there was the sign of a tension deep in his chest coming loose.
The goddess went on.
"The Underworld was fully prepared to welcome you, you know? Three thousand years waiting for your soul, everything ready. But the you of right now is tangled, and far too vivid on top of it."
When Atem drew his brows together faintly, the goddess deepened her smile.
Seto quietly moved a step closer to Atem's side.
Neither protecting nor taking. Simply the distance of being there.
"A vivid soul is the proof of having chosen life. Stronger than the laws of the Underworld is the colour the two of you are weaving now. The gate will not open."
The goddess ran her fingertips through the air, weaving threads there — warp, then weft.
"…And not because I refused?"
"You're welcome to refuse. You're already tangled, after all. In the life on this side. It really is beautiful."
At those words, an answer slowly took shape deep in Atem's chest.
"…Is it all right if I do not return yet. Only for the span of that rounding error called a lifespan, to be here…… Tangled with this soul."
The instant he heard those words, Seto lowered his eyes and received a terribly quiet satisfaction with nothing but his breathing.
The goddess's blue eyes shone like stars.
"That's right. That's just as it should be. Even if it's a rounding error, even if it's no longer than a blink, a soul that has chosen I want to live is beautiful."
Her expression shifted, and this time she spoke a little more seriously, though her voice stayed light.
"To my eyes, the two of you as you are now are very beautiful. So I won't send you back for a while. If anyone has complaints, let the Underworld make them. I'm on the side of here and now."
The goddess pointed a finger at Seto and spoke as though enraptured.
"You really are something. You've dyed him such a beautiful colour."
Seto drew a quiet breath and let a faint smile surface.
But resting there, unmistakably, was the will of I do not intend to have him taken.
"So. Everything is resolved, then."
Seto stated it flatly.
The tone was quiet, but somewhere deep in it there was relief.
The goddess flicked her index finger towards him, an amused smile at her mouth.
"You'd satisfied the victory condition all along, hadn't you. Whether you survive or whether you're called — that's for the two of you to choose."
Atem's eyes wavered faintly, and Seto let a single blink fall, quietly.
The words heard that day sank into their chests, a beat late.
Seto said, shortly.
"…No argument there."
The goddess nodded as though satisfied with the reply, shrugged, and went on in her usual manner.
"So—about time you fired me, don't you think?"
Seto answered flatly, and yet with something like enjoyment.
The procedure for firing her came clearly to mind.
"Correct. You're fired."
"Fine by me. CEO's orders."
Like a desert wind, the goddess vanished in a flutter.
What remained was only the soft air, and each other's body heat.
Atem gazed at Seto.
Seto, too, received that gaze quietly.
Their tangled souls will not come undone any more.
And for now, that is fine.
Atem reached out a hand towards Seto, softly.
Seto took that hand and held it back, calmly, so as not to let it go.
The future is not yet drawn.
Only that, for the span of the rounding error, they go on living the now.
