"Ah— f*ck…"
My head spun violently as my surroundings shifted without warning.
One second I was standing in the dead of night in the park.
The next—
I was in the middle of a forest at dusk.
The transition was so abrupt that my stomach lurched. The sky above me burned in shades of orange and red as the sun slowly sank below the horizon. The air felt colder here, heavier somehow. Only the rustling of leaves and the distant creaking of trees could be heard.
A cold breeze swept past me, snapping me back to my senses.
In front of me, a system window materialized.
[NEW QUEST]
Save Kanae Kocho from Doma
Reward: Depends on performance
Time Limit: 20 hours
Failure Penalty: Death
"…Great."
Where am I?
I slowly scanned my surroundings. Dense forest. No visible roads. No houses. No people.
After confirming there were no immediate threats nearby, I noticed something else — a large arrow floating above the system panel, pointing north.
So that's the direction.
I looked at the system window again, then paused.
My emotions were calm. Too calm.
The blessing must already be active.
So I'm really in the Demon Slayer world.
The entity… was terrifying.
Sending someone across universes so casually. That wasn't just powerful — that was beyond anything I understood.
Although I expected to do quests for him, saving Kanae Kocho from Doma… it will change the timeline to much but shinobu will be more happy and won't have to sacrifice herself but
How does that benefit him?
Is this just a hook? A first quest designed to make me excited for future ones?
Or does this genuinely serve some bigger purpose?
"You will love it."
I remembered his words clearly.
"…Yeah. I do love this quest." 'why won't i i was a full on simp for anime girl's in my previous life like shinobu, mitsuri from the demon slayer verse'
But I'm sure there's something hidden behind it.
Still… what choice do I have?
Let's move.
As I walked in the direction of the arrow, my thoughts turned tactical.
Saving Kanae…
Troublesome.
But maybe doable.
But can I actually do it?
Doma is Upper Moon Two.
His regeneration is absurd. The only reason he died in the original timeline was because Shinobu used herself as poison. Without that, neither Inosuke nor Kanao had enough strength to finish him off.
He's Upper Moon Two for a reason.
And his Blood Demon Art—
Freezing air.
He can literally freeze the air in your lungs, making it hard to breathe and neutralizing breathing techniques.
And then there are his ice clones.
If I compare him to hunters…
He's at least high B-rank. Maybe even A-rank.
His regeneration alone pushes him upward.
And I don't have any ability to neutralize regeneration.
No sealing technique.
No anti-demon skill.
And I don't even have a Nichirin blade.
Without one, I can't decapitate him properly.
But if I manage to get a Nichirin sword…
Then it becomes possible.
Physically, I'm confident I'm above him in raw strength and speed.
But regeneration changes everything.
Then again…
If I look at the quest differently…
I only need to save Kanae.
And in the original timeline, she survived until sunrise before succumbing to her injuries.
So technically, saving her isn't impossible.
But the reward depends on performance.
Which likely means killing Doma yields something far greater.
Should I aim for that? if i fail though i couldn't help but smile wryly as i looked at the failure penalty 'what else did i expect from that bast*rd'
Greed is dangerous.
The forest grew darker as the sun fully disappeared.
And then I noticed the timer.
[16 HOURS LEFT]
"…What?"
I've been walking for four hours?
It felt like barely thirty minutes.
Is my sense of time distorted after interdimensional travel?
That's unsettling.
Soon, faint light appeared ahead.
A town.
The warm glow of lanterns flickered in the distance.
But as I approached, something felt off.
It was too quiet.
Every door closed.
Every window shut.
Every shop abandoned.
Only lanterns remained lit outside the houses, swaying slightly in the wind.
Maybe everyone's asleep?
But no.
The deeper I walked into town, the clearer it became.
It was empty.
Completely empty.
Carriage tracks lined the dirt roads — fresh ones.
The town had been evacuated recently.
So Kanae already sensed the danger.
Suddenly, I heard movement.
I immediately slipped behind a house, pressing myself against the wall.
Two figures moved from house to house, opening doors, checking inside, then exiting again.
I could hear whispers, but not clearly.
I sighed and pulled something from my inventory.
The Mantis Antenna.
"…I hope no one sees me like this."
I placed it on my head.
Instantly, my hearing sharpened.
"…No one in here. Looks like everyone was successfully evacuated."
"We still have to check the rest. Kanae-sama said to inspect everything twice. She sensed a high-ranking demon nearby."
"Do you think it's one of the Twelve Kizuki?"
"Most likely. Let's hurry. The other Kakushi are probably done with their area by now."
"Yeah. I don't want to be the ones slowing everyone down."
They left.
So it's confirmed.
Kanae and Doma are both nearby.
I'll need a good vantage point.
I'm not confident enough to fight Doma head-on.
Observation first.
Intervention at the right moment.
As I moved quietly through the shadows, I heard another set of footsteps.
Alone.
I hid again.
A Demon Slayer walked past, checking the area carefully.
My eyes immediately locked onto the sword at his waist.
Nichirin.
I couldn't help but smile slightly.
Using a burst of speed, I moved behind him before he could react.
A precise strike to the neck.
Controlled.
Enough to knock him unconscious without killing him.
I dragged him into a nearby house and laid him down.
"…Sorry. I'll return this if I survive."
I took the sword.
The moment I gripped it, the blade shimmered.
Its color shifted.
Black.
With faint purple mixed within.
"…What?"
I thought Nichirin blades only changed color once.
Black… and purple?
What does that mean?
A system window appeared.
[NICHRIN SWORD]Rarity: DAttack: +15Special Effect: Can counter demon regeneration
D-grade.
Lower than my usual weapon.
But far more valuable here.
Regeneration counter.
That's what I needed.
Just then, the antenna on my head twitched.
Metal clashing echoed in the distance.
The arrow pulsed urgently.
There.
I moved across rooftops and stopped at the edge of one, crouching low.
Below me—
She stood there.
Purple eyes.
Black hair fading into soft violet at the ends.
Demon Slayer uniform.
Butterfly-patterned haori flowing behind her.
Kanae Kocho.
The Flower Hashira.
Facing her—
Silver-blond hair.
Pale skin.
Rainbow eyes with the kanji for "Two" etched into them.
Doma.
He lazily parried her attacks with a folding fan.
The difference in their expressions was stark.
Kanae was serious. Focused. Every movement precise.
Doma…
Was smiling.
Like he was playing.
Like this was entertainment.
And the air around them was already beginning to grow colder.
