DS Chapter 75 – A Special Physique? Ren's Perfect Compatibility with Sanemi's Rare Blood
Ren rubbed his forehead, still feeling a slight headache.
He glanced around the room before asking,
"Where is everyone else?"
Shinobu counted on her fingers as she answered one by one.
"Aoi went to bed after cleaning up the training grounds."
"Inosuke slept for a long time. When he woke up before dawn, he kept shouting that he wanted to find his 'mother.' I think he was probably planning to ask Ren to become his stepfather."
"And Kanao stayed by your bedside all night. I finally convinced her to get some rest."
At that, Shinobu covered her mouth with a playful smile.
"Oh my~"
"I just realized how lucky I am."
"I only arrived a moment ago, and you woke up right away."
"Is that so?"
Ren stroked his chin thoughtfully.
He sorted through everything Shinobu had just told him.
The first thing that caught his attention...
Was Inosuke.
He actually wants me to become his stepfather?
Of course, Ren wasn't interested in that.
What truly interested him...
Were the other two members of the trio.
Zenitsu Agatsuma.
Tanjiro Kamado.
One was the successor to Thunder Breathing.
The other was the successor to Sun Breathing.
Both were Breathing Styles Ren wanted to study.
Through Inosuke...
He might gradually become acquainted with the other two.
There was no need to rush.
He had plenty of time.
However...
One question still puzzled him the most.
How had Shinobu managed to convince Sanemi to admit defeat?
Someone as obsessed with becoming stronger as Sanemi shouldn't have surrendered so easily.
Looking at Shinobu, Ren asked,
"Shinobu."
"How exactly did you convince Sanemi to concede?"
She blinked innocently.
"It was simple."
"I coated my Nichirin Blade with anesthetic..."
"Then I stabbed him in the kidney."
"He surrendered immediately."
Ren fell silent.
"..."
He was genuinely shocked.
How could such an adorable girl calmly say something so terrifying?
Fortunately...
He had never done anything reckless around her.
Otherwise...
The consequences would have been unimaginable.
Swallowing nervously, Ren asked another question.
"Did Sanemi ask for anything in return?"
"He did~"
Shinobu smiled happily.
"He donated blood to you before he left."
"He's actually quite warm-hearted."
"Blood..."
Ren murmured to himself.
A moment later...
Realization dawned on him.
So the blood flowing through my body belongs to Sanemi.
Thinking about Sanemi's blood...
Ren immediately recalled his unique constitution.
According to the records...
Sanemi possessed an extremely rare blood type capable of intoxicating demons.
Furthermore...
Genya Shinazugawa's unusual ability to temporarily gain demonic traits after consuming demon flesh might also have been connected to that rare bloodline.
If Ren could successfully adapt to the blood now flowing through his body...
It could become an invaluable asset in the future.
It was an unexpected reward.
Just then, Shinobu spoke again.
"By the way, Ren..."
"Your body is rather unusual too."
Ren blinked.
"Mine?"
"Yes."
She nodded.
"When you lost so much blood yesterday, we originally planned to transfuse Inosuke's blood."
"But your body rejected it."
"Kanao and I tried our own blood afterward."
"It still didn't work."
"In the end..."
"Only Sanemi's blood was compatible."
"There was no other choice."
"So the Butterfly Mansion temporarily collected his blood to ensure there was enough for your transfusion."
"Fortunately..."
"Sanemi cooperated surprisingly well."
"He sat there donating blood until nearly dawn before finally leaving."
As she spoke, Shinobu suddenly hopped off the stool.
She seemed to be searching for something.
Moments later...
She dragged over an enormous iron bucket.
The bucket was so large it almost completely hid her small frame.
Ren stared blankly.
"...Don't tell me..."
"That's right!"
Shinobu nodded proudly.
"This is Sanemi's donated blood."
"I still have two more buckets stored safely in my laboratory."
There was unmistakable excitement on her face.
"It's such a shame he couldn't endure any longer."
"Otherwise..."
"I could have collected even more."
Setting the bucket down with some effort, Shinobu's eyes sparkled.
"Do you know, Ren?"
"Sanemi's blood is absolutely fascinating."
"I'd heard before that it could intoxicate demons."
"But after studying it yesterday..."
"I realized it's far more remarkable than that."
She immediately began explaining every conclusion she had reached.
After listening quietly...
Ren mentally compared her deductions with what he already knew.
Almost every conclusion matched.
Her analytical ability truly was astonishing.
She even theorized that Genya's unique constitution was directly related to Sanemi's blood.
After all...
Genya frequently visited the Butterfly Mansion for treatment because of his unusual condition.
Shinobu enthusiastically lectured for more than ten minutes.
Even then...
She still looked reluctant to stop.
Finally, she sat back down on the stool and sighed.
"What a pity."
"I only managed to collect two buckets of such valuable research material."
"Next time..."
"I'll have to invite Sanemi over for another thorough examination."
Ren's mouth twitched.
"...It really does seem like Sanemi is a warm-hearted person."
Just then...
Ren suddenly remembered something.
"By the way, Shinobu."
"Isn't there another competition today?"
"There is~"
"Then..."
"Could you get me a Nichirin Blade?"
Shinobu smiled as though she had expected the request.
She jumped off the stool once again before pulling a long wooden box out from beneath the bed.
Moments later...
She returned carrying a brand-new Demon Slayer Corps uniform and a pristine Nichirin Blade.
Ren's eyes lit up.
"You bought these for me?"
Shinobu scratched her cheek sheepishly.
"No."
"I don't have that kind of money right now."
"The Master provided them for you."
As she spoke, she unfolded the uniform.
"Come on, Ren."
"Hold out your arms."
"Let's see if it fits."
Ren obediently stretched out both arms.
Shinobu carefully helped him into the uniform.
Then she tilted her head in confusion.
"That's strange..."
"I remember you were around one hundred and seventy centimeters tall."
"So why does this look so small?"
Looking at Ren struggling inside the tight uniform...
She couldn't understand what had gone wrong.
Meanwhile...
Ren's face had already turned bright red.
The collar was practically choking him.
Gasping for air, he managed to say,
"Maybe..."
"I grew taller overnight."
"Could you alter it later?"
"And please..."
"Take it off first."
"I'm about to suffocate."
Shinobu hurriedly removed the uniform.
Fresh air finally rushed back into Ren's lungs.
Only then did he let out a long breath of relief.
Before he could recover completely...
Shinobu unsheathed the new Nichirin Blade and handed it to him.
"Now..."
"Try holding your new Nichirin Blade."
