The decision happened in half a second.
Yuki moved forward.
The creature followed.
And Shin'ya went the other way.
He ran for the clearing.
For the sword.
His legs were already complaining. His side was worse than before. His breathing had stopped being quiet somewhere around the fifth creature and hadn't recovered since.
None of that mattered right now.
The sword was close.
Closer.
He grabbed it.
Pulled.
It came free easier than he expected.
No resistance. No dramatic moment. Just — out.
He looked at it properly for half a second.
Long. Single edged. A tachi, if his manga knowledge meant anything here.
No sheath.
"Why didn't she give me a sword earlier," he muttered, already turning back.
Then —
"Why didn't I ask for one."
He decided both of them were idiots and kept moving.
The creature had Yuki pushed back.
Not losing.
But not winning.
Shin'ya moved.
He didn't think about the sequence.
It just came.
Shadow first.
He reached for it — already there, already waiting — and pushed it into the blade.
The weight dropped instantly. The tachi felt like nothing in his hand. Like holding air shaped like a sword.
Then his own body.
Same thing.
Lighter. Faster. Wrong in a way that felt right.
He jumped.
Higher than he should have been able to.
Light on the way down.
He reversed it — pulled the weight back in, added more, let it stack — and the blade became something different entirely.
Heavy. Dense. Real.
He sharpened the edge the same way. Light compressed along the blade until it felt like it could cut thought.
Fire wrapped around it last.
Because why not.
He came down hard.
The strike landed across the creature's back —
Deep enough to matter.
Not deep enough to finish.
The creature turned.
Shin'ya didn't have time to move.
Its hand closed around him.
Tight.
Then —
Up.
The ground disappeared fast.
Too fast.
The forest shrank below him.
He had approximately two seconds before the math stopped working in his favor.
He looked at the sword in his hand.
Then at the ground.
Then at the creature below.
Then at Yuki, still fighting, still moving, not looking up.
He thought about it clearly.
If this works —
Great.
If it doesn't —
She'll get the sword one way or another.
He turned face down.
Still rising.
Then falling.
The wind was loud.
Everything else was quiet.
He exhaled.
Reached for Shadow.
Not the weight trick.
Not a burst.
Something else.
Something he didn't have a name for yet.
Something that felt like it had always been there.
Waiting for exactly this moment.
"I choose you," he said quietly.
The wind took most of it.
"Now bind."
Time didn't stop.
But it slowed.
Just slightly.
Just enough.
The black aura came without announcement.
Not dramatic. Not loud.
Just — present.
Wrapping the blade first. Then his hand. Then spreading quiet and absolute down his arm.
Below him —
His shadow stretched across the ground.
Longer than it should have been.
Darker.
Like it had heard him.
He angled the blade downward.
And slashed toward it.
The shadow split.
Opened.
A circle of darkness spreading outward from the point of impact.
Not a hole.
A door.
He fell through it.
No impact.
No ground.
Just — movement.
Fast. Silent. Directionless in a way that somehow still had direction.
He moved through it toward the creature.
Underneath it.
Then up.
He climbed.
Not with hands and feet.
With intention.
Half his body emerged from the creature's shadow at its shoulder.
The tachi was already moving.
Shadow amplified first —
Then Light —
Weight stacked, edge compressed —
The blade went through its eye.
Clean.
He twisted it.
Pushed deeper.
The creature made a sound he didn't have a name for.
He pulled out.
Moved.
Up its neck now.
The blade came across.
He expected resistance.
There wasn't any.
It was like cutting through something that had already decided to fall.
The creature dropped.
Slow at first.
Then all at once.
Shin'ya stepped back into the shadow before it hit the ground.
Came out three steps away.
Stood up straight.
Silence.
Yuki hadn't moved.
She was looking at him.
Not at the creature.
At him.
Her expression was doing something he didn't have a word for yet.
Something he hadn't seen before.
"...What," he said.
She didn't answer immediately.
"The shadow," she said finally.
"Yeah."
"You went through it."
"Yeah."
"You came out of its shadow."
"Yeah."
A pause.
"And you claimed Ketsugai."
Shin'ya looked at the tachi in his hand.
Still no sheath.
Still slightly on fire at the edges, which he should probably fix.
"...Yeah," he said.
Yuki looked at the creature.
Then at the sword.
Then back at him.
"You claimed it first," she said.
Her voice was completely flat.
Shin'ya processed that.
Then —
"...Oh."
He looked at Ketsugai.
Then at her.
"I didn't — I wasn't trying to—"
"I know."
"I just needed a weapon—"
"I know."
"You can still have it—"
"That's not how it works." She crossed her arms. "Whoever pulls it claims it. You pulled it."
Silence.
"...I'm sorry?" Shin'ya offered.
Yuki stared at him for a long moment.
Then she exhaled slowly through her nose.
The specific exhale of someone recalibrating everything.
"What ability did you choose," she said flatly.
"Shadow movement. Through shadows. Like — entering and exiting them."
"You chose a movement ability."
"It saved my life."
"It saved your life," she repeated.
Another silence.
"You're an idiot," she said.
"I was falling."
"You're still an idiot."
Shin'ya looked at the sword again.
Then at her.
"What were you going to choose?" he asked quietly.
Yuki didn't answer.
She turned away.
Started walking.
"We're leaving the forest," she said.
"The creatures—"
"Are gone. They left when it died."
Shin'ya stood there for a second.
Then he followed.
She didn't look at him for a while.
He didn't push it.
Some things, he was learning, needed space before they became words.
He held Ketsugai at his side.
Still no sheath.
Still slightly warm from the fire.
Above them, through the canopy—
The sky was still doing its slow, patient thing.
Shin'ya exhaled.
Everything hurt.
But they were alive.
And somewhere behind them—
The clearing was empty and quiet.
Ketsugai had been claimed.
Just not by who it was supposed to be.
