Demon Slayer: I am a Demon.

Under the pitch-black night, the little girl walked back, looking much more relaxed and energetic than before.

Su Mu stood under the moonlight, watching the girl's figure disappear from sight before raising his head to look at the full moon in the sky. His hand involuntarily pressed against his abdomen. At this moment, his body felt a strong hunger, and his stomach felt like it was filled with countless acidic churning, as if urging him to find food to fill his stomach quickly.

However, for him, his food was completely different from the girl's. If the girl's food was rice balls and chicken legs, then his food was the girl, or rather, his former kindred spirit.

This was obviously unacceptable to Su Mu, who was once human. Even as a demon, how could he possibly eat his former kind?

But that's how evil spirits are; they have an extraordinary craving for human flesh and blood. If they don't consume flesh and blood to alleviate their craving for a long time, this craving will accumulate over time, and that instinctive desire will become more and more intense.

Feeling an even stronger craving for flesh and blood in his body than yesterday, Su Mu's face looked extremely pale. He didn't even know how much longer he could hold on.

But no matter what, I will never cross the bottom line that I once held as a human being.

"call……"

He took a deep breath, suppressing his craving for flesh and blood, and focused his gaze on his mind.

In his mind, there was a character panel similar to that in a game.

My gaze fell upon it, and the words on it appeared clearly in my mind.

Name: Su Mu

Race: Demon

Lifespan: Unlimited

Abilities: Immortality (pseudo), super healing, robust physique

Flaws: Sensitive to light, wisteria blossoms, Nichirin sword

Status: Hungry, Cursed (from Muzan Kibutsuji)

Blood Demon Art: None

Physical fitness: 3.1 (The physical fitness of a normal adult is 1.)

Agility: 3.2 (The agility of a normal adult is 1.)

Strength: 3.1 (The strength of a normal adult is 1.)

Mental state: 1.2 (The normal mental state for an adult is 1.)

The information that came to mind was simple and clear, allowing him to understand his own situation in great detail.

As a demon, his physique, agility, and strength are almost three times that of a normal human.

Even with rigorous training, it is almost impossible for an average human to improve their physical strength, agility, and power by more than three times.

Generally speaking, if a person can exceed three times their own size, they have already broken their own limits and transcended the limitations of the human body.

It can be said that as a demon, it is a powerful individual that transcends the limitations of the human body in terms of spirit. Ordinary humans have almost no resistance in front of demons. Therefore, demons no longer regard humans as their own kind, but as food.

Of course, the reason why demons crave humans is not only due to the difference in individual strength between the two, but also because of the demons' instinctive need for human flesh and blood. Moreover, human flesh and blood can promote the evolution of the demons' bodies, making them even stronger.

Besides becoming powerful, turning into a demon also grants one near-immortality in terms of lifespan.

To live on is the most desirable thing in the world.

If there is any flaw, it is probably only that he fears sunlight, can only hide in darkness forever, and cannot control his instincts as a demon.

For Su Mu, the most unbearable thing was the uncontrollable instinct of being a demon, the uncontrollable desire to devour flesh and blood. If he did not devour flesh and blood, that desire and his ever-deepening hunger would surge into his heart like a tide.

Perhaps, if we just lowered our standards a little, such unbearable things wouldn't happen.

But for Su Mu, if he were to abandon this bottom line, wouldn't he have completely lost his true nature?

At that time... was he still himself?

Chapter 3 We are already ghosts

For Su Mu, he could never give up the bottom line of being born a human being. Therefore, he had to endure the constant hunger every day and forcefully suppress the urge to devour flesh and blood.

Although he has become a ghost, it does not mean that he has lost his bottom line as a human being. He would never eat people, nor would he become a monster who cannot control his eating of flesh and blood and loses his nature.

……

A man sat under the eaves, looking up at the full moon in the sky, until the moon gradually sank, at which point Su Mu had no choice but to stand up.

We can't stay here any longer, because the sun is about to rise.

As the sun rises and sunlight spills across the earth, even the most powerful demons can only hide in the darkness like rats in the sewers. Even the progenitor of demons, Muzan Kibutsuji, could not escape this fate, let alone an ordinary demon like himself.

Without hesitation, he jumped off the eaves and nimbly disappeared into the distance, away from the town.

Not far from the town was a forest, and in the hazy night, Su Mu's figure moved quickly through the forest.

After walking for a few more minutes, a dark cave appeared. By this time, the sun had risen, and the first rays of sunlight pierced through the distant sky and fell upon the world.

Su Mu looked up at the light that dispelled the darkness and stepped into the cave without hesitation.

Sunlight streamed through the jungle, dispelling all darkness, but the sunlight could not penetrate the deep caves.

The cave was damp and dark. Su Mu silently walked into the darkness, but halfway there, he stopped and silently looked down at his feet.

Beneath your feet lies a thick carpet of white bones—the bones of the old, the children, the men, the women… Each head and bone is like a carelessly discarded takeout box, quietly piled up on both sides of the cave path.

Although he had seen it many times, it was still hard for Su Mu to get used to. After all, even though he had become a ghost, deep down he still considered himself a human being. Watching his fellow humans die as food filled him with an indescribable anger.

"call……"

He took a deep breath, suppressed a certain impulse in his heart, and silently walked forward. The clear sound of chewing reached his ears at this moment.

Su Mu looked up and saw a figure with its back to him squatting down, eating something.

Seemingly sensing the movement, the person who was squatting turned around, revealing a ferocious-looking face with traces of scarlet blood at the corner of their mouth.

In his hand, he held a thigh bone, from which crimson blood dripped onto the ground, staining the damp ground dark red.

Clearly, this is a demon.

"Want some?"

The demon raised the thigh bone in its hand, its scarlet eyes fixed on Su Mu.

Su Mu's face looked extremely ugly at this moment. Although he had become a demon, he would never become a monster who had lost his nature.

"Are you still enduring it?"

The demon stood up, carrying the thigh bone, and approached: "We are no longer human, we are different from those weak species. Do you still consider those weak things as your own kind?"

Su Mu simply stared at the other person coldly without saying a word.

"You remind me of myself at the beginning. I was also very resistant to this kind of food at first, until I couldn't resist taking a bite for the first time and realized how delicious it was. Can you imagine the feeling of tender and juicy flesh bursting in your mouth and the sweet blood flowing down your throat? It's an even more wonderful enjoyment than going to heaven."

"You haven't tried it yet. Once you do, you'll know how delicious it is. I guarantee that once you try it, you'll be addicted."

The purplish-blue demon stuck out its tongue, licked the corner of its mouth, and revealed a look of ecstasy.

Su Mu walked to the side, sat down cross-legged, closed his eyes and didn't speak. However, the bloody smell coming from the thigh bone on the evil spirit's hand made every cell in his body tremble, urging him to swallow it quickly. As long as he swallowed it, he would not only taste the unparalleled deliciousness, but he would also become more perfect.

"This is just ordinary flesh and blood. If it were rare blood, it would be even more delicious."

The demon whispered, its eyes filled with longing: "So far, I haven't encountered a single rare bloodline. I've heard that eating just one is equivalent to eating dozens."

After saying all that, seeing that Su Mu was still sitting there unmoved, the evil spirit was also a little annoyed: "What are you insisting on now? Do you still think you are one of those weak humans? Feel your own desires. The more you insist, the stronger your desire for flesh and blood will become day by day. Even the most determined person cannot suppress this desire after becoming a ghost."

"Do you know the Twelve Demon Moons? Do you know Lord Kokushibo? Do you know Lord Akaza? Do you know how strong their will was when they were human? But so what? In the end, their fates were still the same."

Su Mu, who had kept his eyes closed, opened them at this moment. Looking at the hideous demon in front of him, at its sinister face in the darkness, he calmly spoke after a long while: "So, your father, your mother, and your daughter are also delicacies in your mouth?"

He had learned a bit about the past of the evil spirit in front of him over the past few days. Just like all ghosts were once human, the evil spirit in front of him was the same. In the beginning, the other party had a very happy family, lovely children, a virtuous wife, and kind parents. But all of this was completely destroyed by the other party when he became an evil spirit, all of which were destroyed by his own hands.

"Shut up."

Almost roaring, the demon angrily threw the thigh bone in its hand to the ground, its eyes fixed on Su Mu with viciousness. The memories of being human that it had gradually forgotten after becoming a demon were instantly overwhelmed by unspeakable pain as Su Mu spoke, making it feel as if its heart was being pricked by needles.

Those things you thought you had completely forgotten are still deeply hidden in the inconspicuous depths of your heart. Once mentioned, they are like scars that have been reopened, causing unbearable pain.

After a while, the demon calmed down from its rage, then stared intently at Su Mu with its scarlet eyes: "We are now demons. Even if we were human before, we are now demons. We are no longer the weak creatures we once were. Now, we are noble demons. As demons, we will not die, we will not age, we will not get sick. From now on, we will not lose anything. We are incredibly powerful. We can do whatever we want. Why are you still so concerned about your past identity?"

Chapter 4 Sunshine

"We are already ghosts, why are we still so attached to our past identities?"

It came out of the demon's mouth in an almost roaring voice.

Su Mu did not answer. He simply sat cross-legged on the spot and closed his eyes slightly. He was not attached to his past identity, nor was he truly unable to accept becoming a ghost. After all, becoming a ghost would grant him an almost inexhaustible lifespan, something many people would covet.

Moreover, once you become a demon queen, your strength has already transcended the limitations of the human body. Even the weakest demon is someone who has broken the limits of the human body. Even if you become a demon queen and have the defect of being unable to see the light, it is not a big deal.

What Su Mu truly could not accept was the uncontrollable instinct to devour flesh and blood. He could feel that as he persisted, the desire to devour flesh and blood grew stronger and stronger. This desire would intensify over time. Even though he could still hold on with his willpower now, one day his willpower would be crushed by this ever-increasing desire.

Once his will is crushed, he will become a monster who cannot control his flesh and blood and loses his nature. This is why he is so obsessed with his past identity.

Seeing the silent Su Mu, the evil spirit seemed to see itself, just as it had struggled to persevere when it first became an evil spirit. But in the end, the instinctual desire for flesh and blood in the spirit deepened, and all that perseverance, like a small dam holding back a raging flood, completely collapsed under repeated impacts.

No demon in this world can escape this instinct, not even the first demon, the progenitor of demons, Muzan Kibutsuji.

There is no evil spirit in this world that does not lust after humans.

"One day, you will become like me."

Thinking of all this, and looking at Su Mu struggling in front of him, the evil spirit couldn't help but sneer. It picked up the thigh bone from the ground and silently began to gnaw on it. The tender and juicy flesh burst open in its mouth. Once you tasted it, you would understand how delicious it was and you would definitely become addicted to this kind of food.

If it weren't for the restrictions placed on each demon by Lord Muzan, he would have hunted countless prey every day.

Besides the restrictions imposed by Muzan, there are also those despicable demon hunters who relentlessly pursue them. Once targeted by these people, one can never have peace.

It should be noted that although these demon hunters are also weak humans, they can temporarily possess physical abilities comparable to those of demons by relying on 'breathing techniques', and they also possess Nichirin Blades that can completely slay demons.

Of course, what truly disturbs people's peace is that these ghost hunters will stop at nothing to deal with them, and their favorite method is to find them during the day and then find a way to expose them to sunlight.

The thought of sunlight almost instinctively evoked a sense of disgust and fear.

As the demon devoured flesh and blood, it pondered its own thoughts, its gaze occasionally falling upon Su Mu beside it. It could sense that Su Mu's body had an unparalleled craving for the flesh and blood it was consuming. Although Su Mu forcibly suppressed his demonic instincts, these instincts grew stronger day by day.

"You can't hold on for long."

The demon swallowed a piece of flesh and blood, then looked at Su Mu: "Let me see if you can hold on for another day, two days, or... three days..."

"call……"

Su Mu suddenly opened his eyes, his bloodshot eyes staring coldly at the evil spirit opposite him, but soon his gaze instinctively fell on the thigh bone in the other's hand.
