The atmosphere in the reception room suddenly became heavy because of that long-forgotten history.
Sabito was still stunned by the "Demon Slayer Mark" and the "Curse of Twenty-Five". He looked at Giyu Tomioka with a very complicated expression, as if he were looking at a living legend, a tragic hero who was about to burn himself to illuminate the era.
Tamayo keenly sensed the change in his mood and knew the topic was too heavy. She sighed softly and took the initiative to steer the conversation back to more practical issues.
"Let's talk about you, Mr. Giyu, first."
She looked at Giyu Tomioka, and in his gentle eyes, a researcher's fervent yet rational light rekindled.
"After preliminary testing, I discovered that your blood is even more special than I had imagined."
Tamayo picked up a newly written report, her tone becoming more serious than ever before.
"First, there's the rate at which your blood cells divide. It's ridiculously fast, almost comparable to some ghosts in their normal state."
"This means you possess a recovery ability far beyond that of ordinary people, almost superhuman. Some injuries that would be fatal to ordinary people might heal for you in a very short time."
"And this is only a passive recovery in your body's unconscious state. What would happen if you actively activated this power... Honestly, I don't even want to think about it."
Tamayo's words made Sabito's eyelids twitch.
This guy's body can no longer be described as "human"!!
"More importantly..."
Tamayo's tone grew even more serious. She looked at Giyu and said, word by word, "Your blood is different from that of ordinary people, and also different from that of demons..."
"It's not just a simple Marechi. To demons, it possesses a fatal attraction no less than that of top-tier Marechi."
"But at the same time, it is also a deadly poison!"
"I used your blood to experiment on some of the ghost cells I captured earlier. I discovered that once your blood enters a ghost's cell, it acts like the most potent toxin, instantly destroying its cellular structure, preventing regeneration, and ultimately causing it to collapse and perish."
"This toxicity... I'm certain it's equally effective against the Twelve Kizuki!"
Boom!
This conclusion, like a bombshell, exploded simultaneously in the minds of Giyu and Sabito!
On Giyu's face, a second, and most dramatic, change of expression finally appeared—shock.
He looked down at his hands, his icy blue eyes filled with disbelief.
My own blood... was poison?
A poison capable of killing the Twelve Kizuki?!
Sabito, on the other hand, suddenly jumped up from his seat. His eyes widened as he looked at Giyu and then at Tamayo, so excited that he was incoherent.
"Wait... wait! Ms. Tamayo! You mean... Giyu's blood can kill demons?!"
That's the theoretical view.
Tamayo nodded, and then proposed an even bolder and more outrageous plan.
"My idea is that, using Mr. Giyu's blood as a catalyst, perhaps two things can be created."
"First, it's a deadly poison that can instantly kill demons. If we can find a way to inject this poison into a demon's body, even Upper Rank will surely die!"
"Second..."
Tamayo's gaze swept over the excited Sabito, and she slowly said, "It's a good medicine that can greatly enhance the physical abilities of Demon Slayer Corps swordsmen."
"What?! A medicine to... enhance physical fitness?!"
The Sabito's breathing became incredibly rapid, and its eyes shone like two 1,000-watt light bulbs!
A beautiful image began to uncontrollably appear in his mind.
I no longer have to get up before dawn every day and be chased all over the mountain by Master Urokodaki!
No more swinging a knife thousands of times a day until your arms are too sore to lift!
No more getting one-sidedly beaten by Giyu every day, making you question your existence!
Just one injection!
Just one injection!
You can instantly become as strong as a monster! Strength, speed, and reaction time will increase dramatically!
From then on, he punched the Upper Rank demon, kicked the Demon King, married a beautiful and wealthy woman, and reached the pinnacle of life!
Ha ha!
Thinking of this, Sabito could no longer contain his elation. He rushed to Tamayo, grabbed the table with both hands, his face flushed, and roared, spittle flying everywhere:
"That amplification potion! How long will it take to make?!"
"..."
His sudden shout froze the atmosphere in the reception room.
The fervent expression of a researcher on Tamayo's face froze.
Even Yushiro, who was standing next to him, looked at him as if he were an idiot.
"Well..."
Tamayo let out a long, helpless sigh, as if looking at a child who hadn't grown up yet.
"In the end, this was just an idea of mine."
Her words were like a bucket of ice water, dousing Sabito from head to toe, chilling him to the bone.
"Poison is manageable, since Mr. Giyu's blood is highly toxic to demons. I just need to find a way to purify and stabilize it."
"But..."
Tamayo's expression turned serious. "Mr. Giyu's blood has an alarmingly high rejection rate in the human body. I just conducted an experiment on animals with only a tiny amount of his blood, and without exception, they all exploded and died within seconds."
"These things can't be rushed. Before a perfect neutralizer is found, it would be reckless to inject this drug into the human body..."
Looking at Sabito, whose face had turned deathly pale, she calmly uttered the most terrible ending.
"Their fate will be the same as those laboratory animals."
"Exploded... died from body explosion..."
As Sabito's lips trembled, he repeated those four words, feeling his legs go weak and almost losing his balance.
The "peak of life" that was just endlessly looping in my mind instantly transformed into a dazzling firework made of my own flesh and blood.
That's terrifying!
Seeing Sabito's dejected state, as if he had fallen from heaven to hell, Tamayo's eyes flashed with a hint of pity, but she hardened her heart and turned her gaze back to Giyu Tomioka.
"Therefore, in order to speed up the research, I need more experimental samples."
Her tone was full of apology and pleading.
"Mr. Giyu, I would like to have some more blood drawn from you for subsequent experiments... Would you be willing?"
However, she had barely finished speaking.
Before Giyu Tomioka could react...
The Sabito, who had just been looking lost and dejected, suddenly brightened up!
He seemed to have suddenly figured something out, and he instantly became fully revitalized!
"It doesn't matter!!"
He roared and pounced like a hungry tiger, instantly leaping over the table and rushing behind Giyu Tomioka!
Before anyone, including the two ghosts, could react!
He stretched out his hands and, with lightning speed, firmly pressed down on Giyu Tomioka's two arms that were resting on the table!
Then, he raised his head and gave Tamayo a bright smile, full of the great glory of "for the future of mankind"!
"Tamayo! Please draw as many as you like! Don't be shy!"
"This guy's body is incredibly strong! Even if it's drained, it'll grow back right away! It's fine!!"
Upon hearing this statement...
Tamayo and Yushiro were once again petrified.
Their mouths hung open as they looked at Sabito, who had an upright expression as if he were doing something great, and then at Giyu Tomioka, who was pinned to the table and unable to move. Their minds went completely blank.
So this is what friendship between humans is like?
Giyu Tomioka, on the other hand, did not struggle at all from beginning to end.
He just slowly, very slowly, tilted his head.
Those icy blue, emotionless eyes stared silently and unblinkingly at the teammate behind him who was so brazenly betraying his comrades.
