"Counterattack System loading..."
"You watch Uchiha Itachi grow day by day, your heart filled with unease and anxiety."
"Your name is Uchiha Jukon, an ordinary Genin who has yet to awaken the Sharingan."
"Initial Reward: Three-Tomoe Sharingan."
"Your counterattack begins now; let the Ninja World witness it."
"First of all, my last name isn't Uchiha."
Kiyokawa Izumi tightly gripped the nichirin blade at his waist. Before him was a hideous Demon, perhaps pale and weak from not eating humans for a long time.
Its grey-blue pupils were filled with a craving for flesh, and foul-smelling saliva dripped continuously from its fangs.
"Meat... it's meat..."
The muttering Demon lunged at Kiyokawa Izumi.
Its speed was incredibly fast, hard to imagine for a Demon that had been trapped on Wisteria Mountain without food for so long.
"System, this isn't the Ninja World..."
Kiyokawa Izumi retreated quickly, panting slightly while unable to stop himself from roaring in his mind.
'Did you hear me? This isn't the Ninja World!'
'How the hell am I supposed to extract Chakra?'
'That setting doesn't exist here!'
'Do you know Breathing Techniques? Can you do Sun Breathing? Hurry up and change that damn reward!'
Kiyokawa Izumi's original name wasn't actually this.
Having just undergone Transmigration, he was already on Wisteria Mountain.
The original owner of this body was a piece of trash who overestimated himself while trying to prove his worth.
He hadn't mastered any Breathing Technique and had no talent for being a swordsman, yet he stole his master's nichirin blade to participate in the selection year after year.
He wanted to prove to the old man who adopted him that he, Kiyokawa Izumi, could become a Demon Slayer.
Reality is often cruel.
Despite his determination, he was terrified the first time he faced a Demon.
His limbs grew weak, his courage vanished, and he didn't even have a shred of bravery to fight. He turned and fled, scurrying through the mountains in a pathetic state.
The condition for the Demon Slayer Corps selection is to survive in the mountains for seven days.
But just one day had left the original owner exhausted.
The sun rose as usual, and the original owner, who fell asleep immediately, did not wake up when the sun went down.
Thus, a new Soul appeared in this body.
'I just took a little nap while slacking off at work; is this punishment really necessary?'
Kiyokawa Izumi narrowly dodged the incoming claws.
Having read novels for years, he was no stranger to the System and Transmigration.
Being able to accept it so calmly didn't mean he had a strong heart; it was just that he hadn't reached his breaking point yet.
Simply put, he hadn't reached the point of giving up on himself.
He still wanted to live.
He wanted to go home.
He missed the 200,000 in savings he had worked so hard for over the years and the dozen or so games downloaded in his library.
The big bed at home, the cola in the fridge, the novel chapters he had just subscribed to but hadn't had time to read... he missed all of it.
To hell with this Transmigration, to hell with this System.
To be fair, he really didn't want to become a Demon Slayer.
Perhaps due to distraction, or because his body had reached its limit, his footing became unstable, and he stumbled backward.
Not good, not good, not good... He knew exactly how critical the situation was.
Before he could stand, the ugly and hideous Demon had already lunged at him.
"Heh... heh..."
Heavy panting pressed down from above. An arm covered in black scales, yet exceptionally powerful, pinned Kiyokawa Izumi's shoulders down as sharp claws pierced his skin.
"Weren't you good at dodging just now, human?"
Mocking words drifted over. Smelling the faint scent of blood in the air, the impatient Demon was on the verge of losing control.
'Not good, not good, not good...'
Kiyokawa Izumi almost forgot to breathe as fear spread through his heart.
At the end of the day, he was just an ordinary person who had never seen blood.
For him to encounter a creature like a Demon right away and manage to stay somewhat calm was already quite impressive.
But this was his limit.
With an exhausted body, no mastery of any Breathing Technique, and the original owner's years of sword training not yet absorbed, what did he have to fight a weakened Demon?
There was nothing to rely on.
Having acquired the original owner's memories, he knew very well that this selection took place after Sabito and Makomo, but before Tanjirou.
There were no big shots to carry him; everyone in this batch was just an extra.
The System couldn't be relied on either—maybe there really was a Genin named Uchiha Jukon in the Ninja World waiting for his Counterattack System.
'Izumi, give up. You don't have the talent to become a swordsman.'
The old man's voice rang in his ears. The original owner's master was just an ordinary Trainer, not some retired Hashira.
"Side Mission..."
An emotionless electronic voice spoke.
Kiyokawa Izumi's current state was much worse than imagined.
Between the surging memories and the System's voice, it was overwhelming.
Not being in one's own body was truly troublesome.
The stench of rot grew stronger, and a foul smell wafted over. With a mouth split to the ears and fangs like two rows of serrated teeth, his fate seemed sealed.
"What the hell are you barking about?"
Either erupt in silence or perish in it.
Kiyokawa Izumi suddenly looked up and used all his strength to deliver a headbutt.
The intense pain made his expression even more distorted as blood trickled down from his forehead.
Unnoticed by anyone, a glint of blood-red emerged in his pupils.
"Damn it! Damn it!"
Having its meal interrupted by the resistance of weak prey made the Demon exceptionally furious.
It decided to give the weak human in front of it a quick death.
This hunting game would end here.
It suddenly raised its arm, releasing its hold on Kiyokawa Izumi, intending to use its sharp claws to pierce his heart directly.
For some reason, it accidentally met Kiyokawa Izumi's eyes.
Those eyes, like a Demon's, seemed to have something dotted within the pupils.
These were definitely not eyes a human should have.
The Demon thought to itself.
It had to admit that at this moment, as a Demon, it was actually frightened by the human before it.
Not wanting to die, Kiyokawa Izumi naturally struggled desperately.
"Get off me!"
A sudden punch struck it right in the face, and the Demon, caught off guard, fell backward from the heavy blow.
ء"Damn it, damn it, damn it!"
"It hurts, it hurts, it hurts!"
After all, it was a Demon that hadn't eaten many people, so its strength wasn't so great that it was impossible to resist. It jumped up, its face flushed with humiliation and rage.
At that moment, Kiyokawa Izumi, struggling to his feet, had already drawn his nichirin blade.
Perhaps due to the adrenaline rush, the perception of pain was temporarily ignored.
The world appeared clearly before Kiyokawa Izumi's eyes.
The Demon's movements seemed as if they were in slow motion; he could see them clearly.
Draw the blade!
There was no retreat, no other choice.
Reason told him that at this place and time, his only option was to draw his sword.
The bluish tip of the blade glinted under the moonlight. The muscle memory formed by the original owner's years of hard training drove Kiyokawa Izumi to swing the blade.
