Demon Progenitor Development Project

Soon, Rei and his neighbor, Ms. Sato Reika, became good friends.

Linghua was unlike the other children who were overly lively and restless. She was very quiet, and her gaze towards him did not carry the pity or sympathy that made him feel nauseous.

Lei was very happy to be able to make friends with Linghua. The Ayaki couple were also relieved to see this, and Mrs. Ayaki was even moved to tears.

"I'm tired, but this child finally has a friend."

These days, Rei often plays with Sato Reika and no longer asks where his parents are every day like before.

Even when tired, I still remember to give gifts to my friends.

"Mother, what kind of gifts do girls like?"

Mrs. Ayaki asked in surprise, "Is this for Reika?"

Seeing that Lei nodded, Mrs. Ayaki began to recommend pretty things that girls would like with delight.

Afterwards, Mrs. Ayaki seemed to be deep in thought.

"I'm tired of this age!"

The age of teenage puberty, the beauty of first love!

However, due to their physical exhaustion, it's unlikely that any outstanding women would be willing to marry into their family.

Mrs. Ayaki was very troubled, and as for Sato Reika, there was no way she could accept him as her son-in-law, given how much Mr. Sato doted on his daughter.

Mrs. Ayaki sighed heavily, thinking of Reika's expensive jewelry and dresses that were never the same.

Seeing how enthusiastically Mrs. Ayaki was fiddling with the pretty things on the tray, her brows relaxed. "Never mind," she thought, "I'll look at them later."

Maybe there will be an opportunity in the future.

Mrs. Ayaki comforted herself in this way.

The Sato family, however, did not share this view.

"Muzan, are you sure you intend to turn Rui into a demon?"

Shugo frowned as he looked at the adorable loli Muzan-chan in front of him and the thing she had brought up.

Is it worth becoming a ghost from exhaustion?

Yes, but not much.

The value of the tired is only in terms of combat power. Nowadays, the Oni race is not lacking in combat power; in fact, their combat power is almost excessive.

Moreover, Rei's combat ability wasn't outstanding enough to warrant Shugo giving him a spot.

The number of spots for becoming a ghost is now extremely limited.

Shugo doesn't want to add too many worthless kindred spirits.

Moreover, Lei's personality is really unsuitable; he's too young, and his values ​​haven't been formed yet.

He certainly wouldn't be so lenient as to let Lei play house.

So Muzan, why don't you stop harming this young, innocent boy? Wouldn't it be better to grant the child's wish and let him be with his family?

At most, he might introduce some 'famous doctors' to provide some treatment for the other party.

Muzan sensed the implied rejection in Shugo's voice.

The little girl trotted over and hugged Shugo's leg, looking at him expectantly with her big, watery eyes.

Shugo, used to it all, let out a breath and pulled the loli Muzan into his arms.

One reason after another began to rain down on Muzan, leaving him dizzy and disoriented.

Like all children who are lectured, he reacted the same way.

Muzan jumped down angrily and ran away quickly.

Shugo watched Muzan's departing figure and sighed helplessly.

Well, at least they've learned to discuss things with me now.

Muzan: Hehe, I acted first and informed you later.

Thus, Shugo, who stayed at home without ever leaving the house, received news of a murder that had occurred at the Ayaki family's house next door.

Shugo: ...I want to beat up a kid!

Shugo swiftly followed his senses and found the loli Muzan and the young man with white hair.

It's all over.

Hiiragi closed his eyes.

The anger that came from the loss of control quickly disappeared from his eyes, and Shugo's pupils returned to calm as he stood still.

The loli Muzan opened her innocent big eyes, rubbed her hands together, and spoke in a sweet voice, like the sweet cream flowing from a mochi.

"I'm sorry, Hiiragi."

Sorry, Muzan, I'm not buying into that anymore.

Hiiragi turned and left.

Muzan was shocked and had no choice but to follow, grabbing Shugo's wide sleeve and pleading in a soft, coquettish tone with his head held high.

"sorry,"

Rui, who had just become a ghost, was still in a daze; he had just killed his parents.

Earlier, Rui watched as Muzan accepted the gift, but his expression seemed indifferent, which made him somewhat disappointed.

Linghua said, "You're tired. Do you want to get better? To be like a normal person."

Lei's eyes lit up, and he agreed without hesitation.

Having endured the difficult assimilation process, I was overjoyed and told my parents everything, wanting to share the good news of my recovery with them.

But the parents' expressions changed drastically.

After hesitating for a long time, the father finally made up his mind.

I'm tired, sorry.

I will commit suicide to atone for my sins after I kill you.

The father, clutching a knife, stared at his sleeping son, Lei, his eyes bloodshot.

Such a heinous crime as cannibalism should not be borne by a child!

Lady Ayaki, who rushed over wearing only an outer garment, couldn't bear it. Tears welled up in her eyes as she looked at her husband with pleading eyes. Her well-maintained, fair right hand trembled as she grasped her husband's arm and whispered.

"Please! Don't kill our children."

This is the child she raised with great difficulty and daily prayers to the gods!

At the same time, Mrs. Ayaki also realized that her child had committed an unforgivable sin.

However, at this time, Lei was not actually asleep, because ghosts have a very low need for sleep.

Hearing the words in her ear, her tired fingers, hidden under the covers, gripped the bed tightly.

Why did my father kill me?

My illness is cured.

Because I killed and ate people?

I want to live!

The naive, cruel, and ignorant teenager didn't think there was anything wrong with this.

The memory of the maid's story about a father who drowned while saving his son came to mind.

Why can't my father do it?

How hypocritical!

A surge of intense anger, accompanied by dark emotions, welled up within him. Lei, no longer able to feign it, sprang from the bed and launched a preemptive attack on his father.

The glaring blood bloomed like flowers.

The tall, middle-aged man collapsed.

Mr. Ayaki, who was dying, felt relieved.

That's for the best; it's better to be killed by one's son than for him to kill his son.

Such a thought flashed through Mr. Ayaki's mind, before he was plunged into eternal darkness.

Driven by rage, Rei's anger did not subside after his father's death; instead, he continued his killing spree.

After my father fell ill, my mother followed in his footsteps.

The dying mother, watching her child's gradually blurring form, desperately reached out her hands, trying to touch him.

"I'm sorry, I'm tired..."

Before her mother could finish speaking, her outstretched hand fell to the ground.

Lei, who had just come to his senses, stared blankly at his mother.

"Mother……"

With a click, Muzan arrived.

The memory ends.

Seeing her only good friend leaning against that tall man as if she were praying for something, her already chaotic and exhausted state was instantly triggered.

A strand of snow-white spider silk flew rapidly toward Shugo's brain, about to pierce it.

Black cracks quietly appeared and swallowed the spider silk.

Muzan: ...Ah, this...

Shugo slowly turned around and looked at the brat who dared to attack him, his snow-white eyes filled with a sinister intent.

Victim Shugo: What an annoying brat!

Attacker Rui: The bad guy who bullied Reika!

It's confirmed, these two ghosts hate each other.
