Demon Progenitor Development Project

Kokushibo joined the battle, and crescent-shaped sword energy flew everywhere. There weren't enough of Ubuyashiki Eiji's offspring to go around killing.

However, with sword energy flying around in all directions and covering such a large area, it's inevitable that some people will get hurt.

"Kuroshibo!"

Komaji, wounded by the sword energy, roared angrily.

Being accidentally injured by his own side was already frustrating, but what angered Komaji even more was...

His severed forearm was carried away and landed among the monsters, who, being eager for food, readily accepted it.

There were even small monsters fighting each other over the missing forearm.

That's Komaji's forearm!

That abundant vitality was like a feast for the little monsters that were produced.

Kokushibo felt no shame whatsoever.

Because of their positioning, they were almost face to face; if it weren't for the monsters, they would have looked like they were the ones fighting each other.

Kokushibo: Getting hit means you're weak. Look at me, I didn't get hit at all!

Who do you think you are!

Enraged, Komaji glared, his thick, powerful arms taut with muscles, as he pounded the monsters with punch after punch.

With a series of muffled bangs, one after another, the monsters exploded like lit firecrackers, turning into clouds of crimson blood mist that filled the air.

Upon seeing this, Shugo thought that he should put group combat into the academy's curriculum, no, he should train all the active-duty demons.

It's best to avoid this kind of self-destructive behavior; it's beneath the dignity of a powerful force.

Shugo observed the battles of the former top three Upper Moons and naturally began to lose interest in Ubuyashiki Eiji's fight.

Ubuyashiki Eiji sensed his opponent's deep contempt, his eyes grew even redder, and his tentacle tail swept across, spraying out a ball of corrosive liquid.

Shugo dodged away, and Muzan seized the opportunity to tear off the tentacle tail with his pipe whip and spiked whip.

Ubuyashiki Eiji let out a painful roar.

Ubuyashiki Eiji has indeed become brain-dead due to the fusion, with his IQ fluctuating wildly.

Shugo looked at the souls that were intertwined and entwined like vines within that enormous body.

This fusion monster had no future to begin with.

Confusion and schizophrenia are inevitable; at most, they will cause some trouble.

Of the three souls, two were normal, while the other, a female soul, was covered in various insects, clearly hollowed out.

Judging from the fluctuations in the soul, another male soul is about to awaken.

The young man's head on the right lifted, his eyes opened, filled with twisted hatred and loathing.

In this state of soul fusion, memories can circulate.

Let's just call him Black Mist Lord; the author was too lazy to come up with a name.

Upon learning that his own mother had been used as a tool, he had even lied and worked for his enemy for many years.

Even though his enemy was his own father, his anger remained undiminished.

The first right fist slammed into the middle head—Ubuyashiki Eiji's face.

"You idiot! Now is not the time for infighting!" Ubuyashiki Eiji cursed.

They were about to be beaten to death, and they were still fighting amongst themselves!

Blinded by rage, Kurogiri-kun disregarded everything else and only wanted to kill his own father.

They began a bizarre battle where they were fighting against themselves.

Filial piety and parental love, version 2.0!

Ubuyashiki Eiji, besieged by his two sons, was in a truly dire situation.

His external tentacles had been torn off, and two of his left arms had been twisted off. Inside, the black mist was fighting him for control of his body.

The troll's movements were choppy and jerky, almost like it was dropping frames, which was quite comical.

The remaining ghosts, quite in sync, began to weaken the giant's abilities.

The troll's two heads are still arguing!

Ubuyashiki Eiji: "You unfilial son, we are one now! Are you trying to commit suicide?"

Kurogiri-kun: "This suffering should have ended long ago!"

My mother was in constant pain, wanting to die but unable to.

He/She has had enough of living.

The only one who ever wanted to live was Eiji Ubuyashiki.

Wherever the spatial blade passed, the void was torn apart with dark cracks.

The black thorn whip, like a ferocious black dragon, howled and lashed at the giant's body, leaving deep, bone-revealing wounds.

The crescent-shaped sword energy pierced through the giant's incredibly tough scales.

The icy breath exhaled by the ice doll caused a thin layer of frost to cover the giant's body.

As the giant fell to the ground, it let out a furious roar of resentment, sending sand and stones flying and dust billowing everywhere.

After the battle ended, Ren Guang, who had been temporarily recalled, rushed over and immediately began cleaning the area.

The existence of ghosts must be kept secret.

"Get rid of all possible witnesses."

After giving a few instructions, Shugo picked up Muzan and left; he had to deal with the problem of trouble in his own backyard.

Shugo, holding Muzan's hand, returned to the Infinity Castle.

Seeing this, Doma muttered, "I have a bad feeling about Lord Muzan."

Shugo poked his head out from behind the door and said in a cold voice, "Doma, Akaza, tonight's events are top secret and must not be disseminated."

Doma and Komaji: "Hi!"

*

Shugo and Muzan went into the bathroom.

He had just been in a fight, and he was covered in dust and extremely dirty. People with mysophobia would find it unbearable.

Shugo sank himself into the warm water, sighed, and pulled his beloved lover into his arms. Leaning on his lover's shoulder and rubbing his soft, white cheek against hers, it was simply one of life's greatest pleasures.

Muzan ruthlessly pushed Shugo's face away, poked Shugo's no longer stiff cheek, and gestured for Shugo to speak quickly.

Shugo's eyes were innocent and clear, and he stuck to me like a piece of chewing gum, sweetly kissing my pale lips.

Muzan didn't refuse the kiss. Shugo had been too busy lately, so they hadn't been intimate much, but he himself enjoyed it.

As their lips and tongues became more intertwined, things spiraled out of control, and the content was indescribable.

—Repaired—

Shugo held his lips tightly, refusing to let go, and gently coaxed him until the sound of water gradually subsided, with only a few bubbles occasionally appearing.

*

The first time was in the water, and it seemed pretty good.

Shugo, completely satisfied, wrapped the snow-white body covered in red plum blossoms in a bath towel, picked it up, and carried it back to the bedroom.

Muzan, indignant, cursed, "Despicable bastard!"

They actually brought up his unauthorized involvement in the Kokushibo operation, causing him to unconsciously back down.

Shugo remained calm and composed, carefully drying Muzan's hair, helping him change into his pajamas, and even placing a kiss on the end of his hair afterward.

Muzan's voice was hoarse as he said with dissatisfaction, "You still haven't told me your secret!"

Is this all you remember?

Shugo had no intention of avoiding the question, and calmly began to play "Knight of Destruction" in his mind.

When Muzan saw himself appearing with a mother and daughter in his arms, he thought: (°ー°〃)→（─.─|| )

Muzan's reaction upon seeing the scene of his own demise, where he was known as the Demon Pillar: (⊙_⊙)

Seeing himself stepping into the Ubuyashiki trap: 凸(艹皿艹 )

Muzan: I absolutely refuse to acknowledge that this is me!

Finally, seeing Muzan, who had tried to blend in with others only to be humiliated and lose face, fell completely silent. The entire demon withered away, not uttering a single word.

Shugo whispered in Muzan's ear, asking mischievously, "How do you think you did?"

Muzan pulled the covers over himself, shrank under them, covered his eyes, and pretended nothing had happened. He said, angrily and embarrassed, "Go to sleep!"

"Ghosts don't really need sleep anymore. What a lame excuse," Shugo thought to himself.

Muzan only heard Shugo chuckle before being pulled out of the covers.

Thinking that Shugo was laughing at his Muzan for being so shameful, he was surprised when Shugo simply kissed his cheek and ear lightly, and softly comforted him, "It's different now, isn't it?"

"So that's why?"

"Otherwise, why would I waste so much energy messing with the Demon Slayer Corps?"

A secret joy rose within him. Muzan's face darkened, and he roared menacingly, baring his teeth and brandishing his claws, "That Kamado Tanjiro is the son of Kamado Tanjuro, isn't he? I'm going to kill him!"

"Don't be like that, he hasn't done anything yet," Shugo comforted, his lips moistening Muzan's rosy earlobe.

Hiraga's hand, hidden under the blanket, pressed against his soft abdomen without making a sound.

Muzan, caught off guard by the sudden attack, glared at him.

"Did it stretch?"

"...No!" Recalling his previous erotic experience, Muzan was overwhelmed with shame and said one thing but meant another.

"It seems I still need to work harder." Shugo shrugged helplessly.

Completely distracted, Muzan bit Shugo's hand that was causing all sorts of trouble.

When should I get my ring?

Shugo didn't care at all. He had already left so many marks on Muzan, so it didn't matter if Muzan left one for him. He then changed the subject.

The clumsy player, Muzan, remains silent.

Couple rings are definitely a pair. Shugo only made one initially, but he had the idea of ​​making another one for Muzan to give to him.

"Not done yet? Do you need my help?"

Shugo pulled the petite person into his arms, rubbing his soft lips against hers until they turned crimson, before Muzan kicked him away unhappily.

Thinking of the dozens of bone rings he had ruined before, Muzan thought it over again and again before gritting his teeth and agreeing.

Damn it! That bastard did it on purpose! He knew I always failed!

Muzan belatedly realized what was happening.

"Ouch! Ouch! Ouch! Muzan, give in!" Shugo deliberately cried out in pain.
