Reincarnation as Lower Rank Five in Demon Slayer

In the end, Li Lei gave up shouting, because no one could hear him anyway. But there was one thing Li Lei really wanted to know, and that was—

"He's in that anime, in that place in the anime, is that place dangerous?"

"tired"

A middle-aged woman's voice rang in her ears, filled with guilt towards her children.

"Oh no! Someone's coming."

Li Lei was surprised to find that he could actually understand what they were saying, and it seemed he could even speak it. Unfortunately, they couldn't hear him.

Li Lei: "Sigh!"...( ＿ ＿)ノ｜

"Mother"

The location where Li Lei was standing responded, and only then did Li Lei realize that there was a boy with short white hair, a black dot connected by black lines above and below his right eye, and his left eye was covered by his white hair.

"What is this? Tired—!"

Lower Moon Five Rui! I've been transported to the world of the anime Demon Slayer, and into the body of Lower Moon Five Rui.

At this moment, Lei's mother ran over, hugged Lei tightly with both hands, and cried in his ear:

"You're tired, you can't eat people anymore! It's all your mother's fault for not being able to find a doctor to cure your illness, that's why you've become like this. It's all your mother's fault for being useless."

"No! Mother, I'm fine now."

While Lei was answering his mother's questions, a middle-aged man who looked somewhat like Lei suddenly came out of a nearby house.

The man walked to the opposite side of the tired man and said:

"I'm tired. It's already very late. Go to your room and rest with your mother. Your father has something to do and won't be back until very late today, so don't wait for me!"

At this moment, Lei's mother also said to Lei:

"I'm tired, but your mother will definitely find someone to cure your weak body so that you can grow up healthy like any other child."

"Let's go, you're tired. Let's go rest first. We'll figure out what to do about your health tomorrow."

Exhausted, the mother held back her tears and led her son toward their resting place.

At the resting place, the mother carefully covered Lei with a blanket and then lay down to sleep not far from him.

Lei, lying on the bed, felt strange about his parents' behavior that day. After an hour, he closed his eyes to rest. As a ghost, he didn't need to sleep at night.

At that moment, the door was gently opened, and Lei's father silently walked to Lei's bedside, holding a short knife to Lei's heart, and whispered:

"I'm exhausted! Let's go to hell together!"

Inside Rui's body, Li Lei recalled the scene from Demon Slayer where Rui killed his parents, and was immediately overcome with sadness. Rui, who longed for family affection, had severed the bonds of his own family with his own hands.

As Rui's father thrust his short sword downwards, just as it was about to strike Rui, a snap was heard.

Lei grabbed the short knife aimed at him with his left hand, then swung his right hand. A flash of silver light appeared, and a sharp thread sliced ​​open his father's neck. Blood, like ink, drew bright red dots on the ground.

Inside Lower Moon Five Rui's body, he had no way to stop him and could only watch as Rui made his move.

Just then, Lei looked at his mother and noticed she was holding a silver hairpin. Misunderstandingly, he asked his mother, "Does Mother also want to kill me?"

Inside the body of Lower Moon Five, Lei shouted to Lei:

"I'm tired! Stop! You can't keep making the same mistake, you'll regret it!"

Suddenly exhausted, the mother plunged her hairpin into her heart, and blood flowed from the hairpin.

Seeing the exhaustion in front of me, my mind went completely blank.

After realizing what had happened, he rushed over and hugged his mother, asking:

"Mother! Why did Father kill me, and why did Mother commit suicide?"

Lei's mother gently stroked Lei's face and said to him with tears in her eyes:

"I'm so tired! It's wrong to eat people for the sake of a healthy body, but it's all my fault. I'm sorry I couldn't give you a healthy body. I'm so tired!"

"I originally wanted to take my mother with me, but as her mother, I can't do it."

The mother smiled and said to Lei, "Lei! You'll have to walk this road alone from now on, so take good care of yourself!"

After saying her last words of concern for her mother, who was exhausted, her arm immediately fell limply to the ground.

At that moment, countless tiny snowflakes suddenly began to fall from the dark night sky.

Feeling his mother's body slowly cooling in his arms, Lower Moon Five, Rui, couldn't help but shed tears.

Slowly, the earth began to turn snow-white, becoming clean and empty.

Lower Moon Five, Rui, clutched his chest tightly, feeling the shattering of his heart, and said with tears in his eyes, "It hurts so much here! My heart hurts so much, it really hurts!"

At this moment, I feel as exhausted as a fish out of air, unable to breathe. I feel like I'm about to suffocate, and I can't catch my breath.

"I killed my parents who loved me most with my own hands. I killed both of my parents who loved me most. What's the point of having this healthy body? What's the point?!"

Lower Moon Five - Rui gripped his head tightly with both hands.

"Ah ah ah ah ah ah ah"

"Ahhhhhhhh"

"Ahhhhhhhhhhhhhhhh"

"Aa ...

"Ahhhhhhhhhhhhhhhhhhhhhh"

……

A long, mournful cry echoed around the yard, frightening the birds into scattering.

With a snap, she fainted from overwhelming grief.

Seeing Lei faint, Li Lei suddenly felt dizzy. After the dizziness subsided, he saw Lei, the fifth Lower Moon, running towards his parents with tears streaming down his face.

"Father, Mother, wait for me!"

Rui's parents smiled and said to Lower Moon Five, Rui:

"Tired! Go somewhere else! Go to heaven. Your father and mother will make you pay for the mistakes you made."

"No! Didn't you say you would take me with you? How can Father and Mother go back on their word?"

"Lower Moon Five - Tired," he quickly shook his head.

The parents looked at the determined-looking man, exhausted.

"Alright! Let's all go to hell together to atone for our sins!"

A headache jolted Li Lei awake. Feeling his body, Li Lei instinctively looked at himself, noticing his greyish-white clothes and white hair.

"This is... Lower Moon Five Rui's body!"

It seems that after Rui's soul left, I somehow became the master of this body.

At this moment, Li Lei suddenly felt two forces, one large and one small, within his body. The larger force, in his perception, was constantly changing shape according to his thoughts.

The physical properties of the material also increase linearly with the increase in the degree of control applied to it, resulting in a linear increase in its strength and hardness.

This is the Blood Demon Art that Rui, the fifth Lower Moon, originally used to control threads. What is smaller in comparison?

"A Blood Demon Art born from me! What will my Blood Demon Art be like?"

"Tired! Human life is so fragile and vulnerable! As a demon with an immortal body, you don't need to grieve for such a life."

At this moment, a voice came from the side.

Muzan Kibutsuji emerged from the shadows and stood before Li Lei, saying:

"Tired! You are a ghost, possessing an infinite lifespan and immense power. In your long lifespan, you can have any kind of affection you desire. There's no need to be sad or upset about this!"

Muzan, holding a bowl of blood, approached Li Lei, half-squatting down and placing the bowl of blood in front of him. He then said to Li Lei:

"Tired! Drink this bowl of my blood, and you will become stronger. You will be able to have as much of those false human emotions as you want."

Li Lei looked at the man before him. Kibutsuji Muzan, the progenitor of demons in Demon Slayer, was someone that no one except Yoriichi could defeat in a direct confrontation.

Li Lei looked at Wuzan before him and felt a surge of fear.

"Am I going to die right after transmigrating?! (((;?_?;)))"

Li Lei looked at the bowl filled with Muzan Kibutsuji's blood, wondering about Muzan's intentions.

"As the progenitor of demons, shouldn't he be able to see through the thoughts of demons? He's no longer the Lower Moon Five, surely he knows that?"

Li Lei reached out and picked up the bowl filled with Muzan's blood, then resolutely downed it in one gulp.

As Muzan watched Rui finish drinking his blood, a smile appeared on his lips. He recalled how Rui had broken free from his control earlier due to immense sorrow.

"It seems that we can't use people with too much humanity to create ghosts in the future. But Lei is truly someone I value."

At this moment, Li Lei felt that all the cells in his body were getting stronger, and his two Blood Demon Arts were also getting stronger. Among them, the Blood Demon Art that arose because of him was getting stronger the fastest, almost as strong as the Blood Demon Art that controlled the threads, or even slightly stronger.

Muzan sensed that Li Lei had returned to his control. Apart from not being able to sense Li Lei's thoughts, he was otherwise unharmed.

Oniwu Tsuji Muzan thought to himself:

"Perhaps his constitution underwent a mutation during the great grief, and such trivial matters are not important to him. As long as it is not a ghost that can overcome sunlight, it is not important to him."

"I'm tired! I'm leaving now. You can come find me if you need anything." With that, Muzan left.

"Take care, Lord Muzan."

After Muzan left, Li Lei let out a long sigh.

"Ugh--"

"From now on, I will live in the world of Demon Slayer, but I have become a demon again. Demons cannot be exposed to direct sunlight, or they will turn to ash."

"Hmm! Or maybe not even ashes (=_=) or the same goes for getting your neck slashed by a Nichirin Blade. They're really creatures that die very cleanly!"

Most importantly, they want to eat people! Ah, this! As a "little flower" of our motherland who has received nine years of compulsory education—"I can't do it!"

"I don't want to think about it anymore. Let's bury our parents who are exhausted first!"

Li Lei found an iron shovel in the yard and dug a pit in the center of the yard to bury his parents.

"Wait a minute, it seems that demons in Demon Slayer can eat other demons, so does that mean they don't have to eat people anymore!"

Okay! Next question.

"What will my own Blood Demon Art look like? I can't wait! I'll try it out!"

"I can feel it now, it feels like something is about to come out of my body."

With a soft "smack," a small fleshy ball landed in Li Lei's palm. ヽ((◎д◎))ゝ

"Little meatball?"

"Wait, why is it a tiny fleshy ball the size of a ping-pong ball? Could it be that my Blood Demon Art will become the weakest Blood Demon Art in history? No, no! I just felt that it was very strong!"

"Hmm! Let me feel it more carefully."

My mind entered my body and found the two Blood Demon Arts within them. I then strengthened my connection with the Blood Demon Arts that had been created because of me.

After 10 minutes of careful sensing, I finally perceived its characteristics: parasitic absorption, remote control, and the ability to change everything.

"It looks like a parasite!"

So the "little fleshy ball" was a parasite that split off from me. It seems my Blood Demon Art is still quite powerful.
