"Damn it!"
"Where did you bring me?"
"Is this still my country?!"
Before Yasui Ryosuke could react, a flood of memories forcefully inserted themselves into his brain, stirring wildly.
During the Meiji era, it was rumored that demons devoured humans at night.
There were also Demon Slayers who formed the Demon Slayer Corps to hunt down demons and protect humanity… Isn't this the world of Demon Slayer: Kimetsu no Yaiba?!
What the hell!
Yasui Ryosuke cried, made a fuss, and then… no, he was heartbroken.
Heartbroken!
Come on, buddy, I haven't even used the hundreds of thousands of original stones I saved up!
And no one is protecting Konoha Village anymore!
I didn't even get to wear my family-heirloom Liu Tao!
The several terabytes of study materials on my computer haven't been deleted.
The browser history on my phone, along with all those miscellaneous fruit apps and games like 'Agent' and 'Beautiful World,' haven't been formatted yet.
What if the police uncles break into my phone… "My lifelong reputation!"
Yasui Ryosuke cried out to the heavens.
He was an upright, honest, and good-hearted flower bud of the motherland; he hadn't stumbled upon any great fortune, so how did he get conscripted and brought here just by staying up late and sleeping?
However, facts proved that staying up late really could lead to sudden death.
Is the performance for transmigration so hard to achieve now?!
Good news: Yasui Ryosuke had meticulously read the original story.
Bad news: He was about to die.
"Pfft!"
A sharp pain tore through Yasui Ryosuke's body.
He convulsed uncontrollably, spitting up blood.
Damn it!
This original host was a sickly person with not long to live; his parents had been devoured by demons, and he had been saved by a one-legged old man who looked fierce and walked with a cane.
"I'm already this miserable… System bro, stop hiding!"
Yasui Ryosuke cried out in pain.
Hiss—
A static sound rang in his mind.
[Demon Extermination System activated.]
[The host can gain lifespan and cure chronic illnesses by slaying demons, and can also use lifespan to learn Breathing Techniques and sword skills.]
"…"
Yasui Ryosuke's lips twitched: "System."
[Hm?]
"How much longer do I have to live?"
[Congenital liver failure, one year at most, tee hee~]
"Tee hee your sister!"
Yasui Ryosuke was enraged.
My ♦ mother →
Me?
Use this sickly body to slay demons?
Are you kidding me?!
Not to mention he didn't have a nichirin blade, just the lifespan points alone were a pain in the ass!
What kind of system makes its host spend their life force?!
I'm screwed!
Yasui Ryosuke roared: "How the hell am I supposed to slay demons with this body?! By relying on kindness to make them slit their own throats?!"
[host, don't panic. At least it's a liver problem, not a lung problem. You can still alleviate it a bit with a strong physique and Breathing Techniques, and die a bit slower.]
"…"
Yasui Ryosuke was practically grinding his back molars: "Damn it! What factory did you come from, system? I'm going to complain about you!"
Zzzzz—
The static continued, and the system played dead.
Fine!
You're amazing!
Yasui Ryosuke spent a Kun hour accepting the facts.
What else could he do? Practice, learn!
Not slaying demons would truly lead to death!!!
"Ahem!"
A deliberate cough sounded at the door, interrupting Yasui Ryosuke's accusations against the unscrupulous system.
Yasui Ryosuke looked up.
An old man stood at the door, short in stature but exuding a steady presence.
He had white hair and a white beard, and a serious, fierce expression.
Most striking was the Wolverine-like scar under his left eye, and a prosthetic on his missing right leg, supported by a wooden crutch.
Kuwajima Jigorō!
The former Sound Hashira and Trainer of the Demon Slayer Corps!
Agatsuma Zenitsu and Kaei Gaku's master.
"Awake?"
Kuwajima Jigorō spoke with concern, but more so with sternness: "You're a tough one."
"Thank you, senior, for saving my life."
Ryosuke stood up to bow, but his body was weak, and his movements were somewhat clumsy.
"Hmph!"
Jigoro hobbled a few steps closer with his crutch, his gaze like a knife sweeping over Ryosuke's body.
"Your body… it's like rotten wood eaten hollow, ready to fall over with a gust of wind. You're even weaker than this old man. Congenital liver failure, depleted qi and blood—it's a miracle you've lived this long."
Yasui Ryosuke: "…"
That stings, old man!
There's no need to emphasize it at this point!
"Was it from birth?" Jigoro asked.
"Yes."
"Hmm—"
Jigoro frowned deeply, "The physicians in the Demon Slayer Corps might be able to help you recuperate and prolong your life for a while."
Hearing this, Yasui Ryosuke smiled bitterly to himself.
According to the original host's memories, it should be the late Meiji era, about 10 years earlier than the original story's timeline.
Kochou Shinobu and Kanae were still little kids, and the Butterfly Mansion hadn't even been established!
Recuperate? Recuperate my ass!
Let alone trying to cure congenital organ failure with the medical technology of that era?
That's like a toad chasing a frog—you're ugly, but you play it fancy.
As for becoming a demon… Heh heh—
Scum Boss Muzan doesn't pay wages, has no social security, and lays people off at the drop of a hat. Modern black-hearted capitalists would praise themselves for being too kind after seeing him!
Even if Yasui Ryosuke wanted nothing but to enjoy his cross-dressing.
As soon as Scum Boss Muzan peered into Ryosuke's memories, he would know where the blue spider lily was.
Given Muzan's nature, after achieving his goal, he would likely just crush Ryosuke.
I'm not even afraid of the sun and becoming a Joestar-level being, so why would I need you demons for anything?!
The demon path is completely unfeasible, directly passed.
The current situation is that if Yasui Ryosuke doesn't slay demons, he will die! He'll be cremated in a year!
The system's life-draining method is the only way for him to survive!
A strong will to live and a sense of crisis overwhelmed all of Ryosuke's hesitation and lucky.
Jigoro watched the changing expressions on Ryosuke's face, thinking he was despairing, and was about to say something like "cherish your remaining time."
Yasui Ryosuke moved.
He slowly propped himself up and bowed ninety degrees to Jigoro.
"Coach! I want to play basketball… Uh, no, wait!"
Yasui Ryosuke, having switched channels, spoke again.
"Senior! I want to slay demons! Please teach me!"
