Special Constitution

"I've been waiting for you!"

The corners of Tendo Hiruma's mouth rose, his voice filled with excitement.

Demon: "???"

Was something wrong with this guy?

As the Demon hesitated, a blade flashed with a swish, slicing through the air like lightning with a terrifying force as it shot straight for its neck.

Blood spurted in an instant. The Demon stared at Tendo Hiruma in disbelief as he retreated.

This kid was strong.

Hiruma set the bag of rice aside. He did not want to waste food; getting Demon blood on it would be disgusting.

He flicked the blood off the kitchen knife, raised it at the Demon, and said with a smile:

"I'm just saying, you're so weak. I'm only a child."

The contempt in his tone, coupled with those golden eyes looking down on it, made the Demon furious.

It was like being mocked by a roast chicken sitting on the dinner table.

"Brat, you're courting death!"

The Demon gritted its teeth, wishing it could tear Hiruma apart alive. It had decided to swallow this arrogant human brat alive, one bite at a time.

A bluish-black streak of lightning tore through the silver moonlight. Sharp claws ripped through the air and lunged for Hiruma's head.

A crisp clang echoed along the forest path. The kitchen knife snapped in two, and a bloody gash appeared on Hiruma's chest. He had still underestimated the Demon's strength; an ordinary kitchen knife was no match for it.

"Hahaha! Little brat, keep acting tough!"

The Demon immediately grew smug, pointing at Hiruma and laughing madly. Then it pointed down the road and said:

"Brat, I'll allow you to run for a while first!"

Hearing that, Hiruma turned and ran. The Demon remained where it was, not because it was kind, but because its Blood Demon Art was poison.

Before long, that little brat would be unable to move.

Their brief exchange had made the Demon realize that the human child was not simply arrogant. He truly was strong, but he was still too inexperienced.

Taking advantage of Hiruma's escape, the Demon licked the blood from beneath its nails clean. Slowly, it actually ate its entire hand.

"Fragrant! So fragrant! Hahaha! This is definitely the most delicious blood in the world!"

The Demon hugged itself, its body trembling and twisting as it stared drunkenly at Hiruma, whose steps were growing slower and slower.

"D-Damn it!"

"Poison!"

Hiruma cried out and collapsed to the ground.

The Demon was so excited that its face warped, its features squeezing together. Using all four limbs like a beast, it raced toward Hiruma.

It opened its huge, bloody mouth and bared its sharp fangs as it bit toward Hiruma's neck. Strange grunts came from its throat, and its eyes seemed ready to take on Hiruma's shape.

Just as its fangs were about to touch him, a blade flashed too quickly for the Demon to react. In an instant, its world turned upside down.

By the time the Demon came back to its senses, its head had already been separated from its body.

Hiruma held half of the kitchen knife. The wound on his chest had healed completely, with only his torn clothes proving that he had been injured.

He kicked the Demon's body away and used the blade to nail its head to the ground.

"You monsters really are tenacious. You can still live after your head and body have been separated. How fascinating."

Hiruma patted the Demon's cheek, wearing a gentle smile as he offered a curious compliment.

But in the Demon's eyes, it saw a devil. A madman. If Muzan had given it dignity and absolute suppression—

Then this human gave it fear, especially that cold smile that did not reach his eyes.

The Demon finally realized that all of that weakness had been an act.

"How is that possible? My Blood Demon Art can poison even a cow! How can you be fine? Impossible! Absolutely impossible!"

The Demon let out a hysterical roar. It refused to accept this. Every roar pulled its facial muscles against the blade, spilling bluish-black blood all over the ground.

"Because I have Rare Blood!" Hiruma answered. He was not lying. He had indeed been poisoned. Though he had done it deliberately, it still hurt.

"More importantly, you're just too weak!"

Even as he explained, he did not forget to mock it.

This world had Special Constitutions, usually known among Demons as Rare Blood.

As a transmigrator, Tendo Hiruma also possessed a Special Constitution, and a very powerful one at that—especially his blood.

His Special Constitution granted him three abilities.

First, extremely sharp senses, somewhat similar to Spider-Sense, though it was still being trained.

Second, remarkable regenerative abilities. Although they could not compare to a Demon regrowing severed limbs, he was still quite satisfied.

Third, his blood possessed unparalleled adaptability. This was Tendo Hiruma's greatest advantage.

After two and a half years of research, he had discovered that people who consumed his blood could also recover from injuries faster, though the effect was weaker. His blood could even cure illnesses.

Most importantly, his blood could be preserved for a long time, remaining fresh for up to a month.

Of course, he had to thank old man Kuwajima's body for supporting all those research results.

Tendo Hiruma had deliberately allowed the Demon to hit him. He merely wanted to see whether he could be poisoned and strengthen his resistance to toxins, since Demons' Blood Demon Arts came in all kinds.

Unexpectedly, he had struck gold. This guy's Blood Demon Art really could poison people.

Hiruma stretched, glanced at his shredded clothes, and stared resentfully at the head nailed to the ground.

"With my clothes torn up like this, the old man is going to scold me again."

"Tell me, how are you going to compensate me?"

Demon: "???"

Did he even hear himself? How could a thirty-six-degree mouth say something so cold?

Looking again at the body lying not far away, the Demon completely broke down.

Its head and body had already been separated, yet the culprit still wanted compensation. Was there any justice left in this world?

"Damned human, kill me if you dare!"

"Otherwise, I'll definitely eat you!"

As the Demon made threats, Hiruma placed his hand by its mouth and said sincerely:

"Here. Eat it."

The Demon looked at Hiruma in confusion and suddenly felt that this person was actually rather nice.

So it opened its mouth and bit at him. Hiruma easily dodged and mocked it while he was at it:

"I gave you a chance, but you couldn't take it!"

"Are you playing with me?!" the Demon roared.

Hiruma patted the Demon's little head, looking at it as though it were an idiot.

"Congratulations, you got it right!"

"Y-You... you... you..."

The Demon was so enraged that it could no longer speak coherently. Even its bluish-black face had turned red.

Was this person a monster?!

"By the way, it's time for questions and answers!"

Ignoring the Demon's curses, Hiruma sat down in front of it and asked with a smile:

"Mr. Trash Demon, I'd like to hear about your boss. How about we have a little chat?"

"Is something wrong with you?!"

"What the hell do you mean, boss or no boss?!"

The Demon cursed, its attitude exceedingly hostile.

"Of course I mean Muzan Kibutsuji!"

Hiruma's words were like a devil's whisper, echoing in the Demon's mind. It was stunned.
