I, Yuhaka, am hungry!

At this moment, Muzan Kibutsuji realized something: the Demon Slayer Corps' arrival in the Infinity Castle was premeditated, and Muzan Kibutsuji's expression immediately turned ugly.

Meanwhile, on the Demon Slayer Corps' side...

When the Demon Slayer Corps arrived at the Infinity Castle, they were stunned by its bizarre interior design. The various sizes of paper doors and the Japanese-style interior decoration were scenes that the Demon Slayer Corps members had never seen before.

The Pillars who had seen the story were also slightly surprised by what the Infinity Castle looked like, since the visuals in the manga were completely different from reality.

Soon, under Kagaya Ubuyashiki's orders, the Demon Slayer Corps swordsmen split into small teams and searched for traces of demons in the surrounding area. Although Sirin had control of the Infinity Castle, she was unable to sense any movement inside the castle.

However, Kagaya Ubuyashiki had no complaints about this. He was already quite good at controlling the operation of Infinite Castle, and he didn't ask for too much.

Meanwhile, inside the Infinity Castle, Muzan Kibutsuji learned from Nakime that the Demon Slayer Corps had split up. So Muzan Kibutsuji ordered the Upper Rank Demons to take care of the Demon Slayer Corps members, which was also a good opportunity to eliminate all the Demon Slayer Corps swordsmen to avoid causing trouble for him in the future.

At this moment, Muzan Kibutsuji did not notice the short figure of Hime Rin in the Demon Slayer Corps.

Chapter 504 [The Infinite City Conquest (Part 2)]

Under Muzan Kibutsuji's orders, the Upper Rank demons of the Twelve Demon Moons learned that members of the Demon Slayer Corps had invaded the Infinity Castle. Upon hearing this news, the Upper Rank demons initially had incredulous expressions, while Muzan Kibutsuji's reaction to the Upper Rank demons was quite normal.

After all, even the Twelve Demon Moons didn't know the location of the Infinity Castle deep underground, let alone the fact that the Demon Slayer Corps had discovered it. Moreover, the Infinity Castle was located deep underground, and even the Demon Slayer Corps would need several years to dig it down from above.

But Muzan Kibutsuji was puzzled as to how those Demon Slayer Corps flies had discovered that the Infinity Castle was located here.

This is the question that Muzan Kibutsuji most wants to know. To be honest, Muzan Kibutsuji doesn't really imagine what kind of ability the Demon Slayer Corps has to find the Infinity Castle. He suspects that it might be the work of Tamayo, who betrayed him in the past.

Muzan Kibutsuji was a little angry about this. After dealing with these Demon Slayer Corps swordsmen, Muzan Kibutsuji planned to go find the woman who betrayed him during the Twelve Demon Moons and let her know the consequences of angering him.

Soon, under Muzan Kibutsuji's orders, the Upper Moon demons also began to move. Upon hearing Muzan Kibutsuji's command, they split into groups to search for the Demon Slayer Corps swordsmen.

Whether it was due to the influence of the world's consciousness or not, the path chosen by the Upper Moon demons was exactly the same as the plan of Kagaya Ubuyashiki and his group.

.......................................................................

In the following time, while searching for each other's targets, the Demon Slayer Corps also encountered demons and ghouls who had been captured by Muzan Kibutsuji to serve as guards inside the Infinity Castle. These rabble were easily dealt with by the Demon Slayer Corps swordsmen. After all, those demons and ghouls had been hungry for some time, and their strength had decreased considerably. Basically, most of the demons were no match for ordinary Demon Slayer Corps members.

Soon, the Demon Slayer Corps members, who had been fighting their way through, encountered each other's targets.

Gyomei Himejima and his group soon encountered Upper Moon One, Kokushibo. Having seen Kokushibo's Moon Breathing technique in the manga, Gyomei Himejima and his group were quite familiar with it and devised a countermeasure.

Most importantly, Muichiro Tokito's mastery of Ripple was his strongest trump card against Kokushibo. Thus, with the help of Gyomei Himejima and Sanemi Shinazugawa, Muichiro Tokito accomplished the great feat of destroying the "ancestor," albeit with some difficulty, but at least he still won.

Of course, Muichiro Tokito doesn't acknowledge that this guy is his ancestor either.

Meanwhile, Shinobu Kocho also easily defeated Upper Moon Two, Doma. Taking advantage of Doma's initial underestimation of her opponent, Shinobu slashed at him. Doma simply raised his iron fan to block Shinobu's attack, but unfortunately, his attempt to show off backfired and he was killed by Shinobu.

After all, Shinobu had consumed a lot of enhancement potions before dealing with Doma. Using a Nichirin Blade made from materials from Monster Hunter World and her own ki training, Shinobu cut off Doma's head with a single strike. Doma, lacking a strong desire to live, was unable to heal and died under Shinobu's blade.

To be honest, Obanai Iguro and Mitsuri Kanroji, who were standing to the side, also looked embarrassed. They had prepared to fight to the death with Upper Moon Two, but no one expected that Doma would die so quickly. Even Shinobu Kocho, who killed Doma, didn't seem to have reacted yet.

Shinobu Kocho's face now looks like she's thinking, "That's all?"

The battle on Upper Moon Three's side, Akaza, was much more intense than on Shinobu's side. However, Tanjiro, who had learned the Breath of the Sun, quickly defeated Akaza. Although it was a bit difficult, with the help of recovery medicine, Giyu Tomioka and the others did not lose much of their fighting ability.

When Yuhka faced Upper Moon Four, the abilities manifested by Upper Moon Four [Hantengu]'s clones were very troublesome for the Demon Slayer Corps, but they posed little threat to Yuhka. Moreover, Yuhka's strength far surpassed that of Hantengu. Although Hantengu's clones entangled Yuhka, they were all dealt with by Yuhka's nuclear-explosion-like attack.

On the side of Upper Moon Five [Jade Pot], Ji Lin only used one sword to eliminate Jade Pot. Jade Pot, whose neck was cut off by the Xuanyuan Sword containing ripple energy, died instantly. Jade Pot was also eliminated by Ji Lin in an instant when he saw Ji Lin, after all, Jade Pot's appearance was too disgusting.

If things had been more normal, maybe he would have died a little slower.

The situation was even worse for Upper Moon Six [Daki] and [Gyutaro]. At first, Daki was completely bewildered when she saw the Titan armored force. Although Muzan Kibutsuji had ordered them to fight the Demon Slayer Corps, Daki was still clueless when she saw the Titan armored force, since she had never seen Titan armor before.

Then, the Titan mechs saw her and charged towards her. Even a fool would understand that those metal lumps meant no good, so Daki launched an attack on the Titan mech army. Of course, dealing with Titan mechs capable of flattening the Fourth Herrscher was a different story...

So dozens of Titan mechs surrounded Daki and started yelling "Enemy! Damn! Enemy! Attack!" Daki, who was being beaten so badly, cried and immediately called for her brother Gyutaro to come and save her. But as soon as Gyutaro came out, he was also beaten in the same way.

At the command post, Kagaya Ubuyashiki and the others looked embarrassed as they saw what was happening on the monitor. They hadn't expected Upper Moon Six to be so humiliating, especially since Upper Moon Six had almost killed Tengen Uzui in the manga.

But now... well, they don't know what to say either...

.................................................. ...........................

After eliminating all the Upper Moon demons, the entire team rested briefly before searching for Muzan Kibutsuji's room. Soon, the Demon Slayer Corps found Muzan's room.

Chapter 505 [Demon Slayer Ends]

Muzan Kibutsuji sat on a cushion with a gloomy expression. He never expected that the Upper Moon demons would be wiped out in less than half an hour.

Upper Moon demons aren't pigs, even if they were six pigs, it would take much longer to kill them.

Soon, as the paper door before him was sliced ​​down by the Nichirin Blade, a large group of Demon Slayer Corps members arrived before Muzan Kibutsuji. Muzan, with a grim expression, looked at the Demon Slayer swordsmen before him and said:

"Those upper-winged warp wheels are utterly useless; they can't even stop you flies..."

Upon hearing Muzan Kibutsuji's words, Sanemi Shinazugawa of the Demon Slayer Corps also looked at Muzan with a sour expression and said in a very unpleasant tone:

"Huh? If they're trash, then you're the king of trash among them?"

Upon hearing Shinazugawa Sanemi's words, Muzan Kibutsuji's face immediately turned ashen, as if he had eaten shit. However, for the foul-mouthed Shinazugawa Sanemi, seeing Muzan Kibutsuji's discomfiture brought him secret pleasure. Of course, many members of the Demon Slayer Corps present were also quite pleased.

Muzan Kibutsuji was displeased and angrily cursed as he swung his arm at the Demon Slayer Corps. Instantly, several sharp spikes flew towards the Demon Slayer Corps like darts. The Pillars of the Demon Slayer Corps present were prepared for Muzan Kibutsuji's sudden attack. Sanemi Shinazugawa swung his sword and deflected the spikes that Muzan Kibutsuji had thrown at him.

The spikes that bounced back severed a lock of hair near Muzan Kibutsuji's ear. Seeing this, Muzan Kibutsuji was filled with rage. Soon, Muzan Kibutsuji transformed. Now, Muzan Kibutsuji had several mouths with sharp teeth, several pairs of spiky kagune and feather-like wings on his back, a flat tail kagune at his tailbone, and some vital parts of his body were covered with ghoul kagune.

Muzan Kibutsuji, with an arrogant expression, looked at the astonished Demon Slayer Corps members and said:

"See that?! This perfect body! Abilities completely different from those useless creatures, I am the only one who can be called the most perfect being!"

Upon hearing Muzan Kibutsuji's boastful remark, the Pillars present exchanged glances before making way for the short-statured Ji Lin. Ji Lin, now dressed in the same clothes she wore during the assassination attempt on Muzan, waved her small hand at him and said:

"Hello~ Mr. Kibutsuji Muzan, have you missed me~"

Upon seeing the person who had almost killed him appear before him, Muzan Kibutsuji's face contorted as if he'd been forced to eat excrement and then swallowed it whole... Uh, isn't that analogy a bit too disgusting?

When Muzan Kibutsuji saw Hime Rin, he couldn't help but recall the time he was almost killed. It had been a long time since then. After being terrified by Yoriichi Tsugikuni, Muzan Kibutsuji hid for decades until he managed to kill Yoriichi Tsugikuni.

Previously, Muzan Kibutsuji, who had been assassinated by Ji Lin, was once again frightened and hid, hoping to survive until Ji Lin died of old age and then crawl out of the Infinity Castle. However, Muzan Kibutsuji's plan failed, as he did not expect anyone to find the location of the Infinity Castle.

...........................................................................

When Ji Lin appeared in front of Muzan Kibutsuji, Muzan was also frightened. The power of the Ripple technique used by Ji Lin far exceeded the Sun Breathing technique that Muzan had seen. Coupled with Ji Lin's strong strength, Muzan was almost completely overwhelmed. The surrounding Demon Slayer Corps also retreated to a safe distance to let Ji Lin deal with Muzan.

Although they also wanted to join Ji Lin in fighting Muzan Kibutsuji, their strength would only hinder Ji Lin. After all, they did not have the ability to eliminate Muzan Kibutsuji. Apart from Muichiro Tokito, their attacks were basically useless against Muzan Kibutsuji.

Not to mention that the current Muzan Kibutsuji is still a version enhanced by ghoul abilities.

Therefore, the Demon Slayer Corps' current task is to prevent Muzan Kibutsuji from escaping again. If he escapes this time, it will be very difficult to catch him again.

During his battle with Ji Lin, Muzan Kibutsuji shamelessly created numerous clones in an attempt to escape, but unfortunately, the Demon Slayer Corps swordsmen and Titan armored vehicles around him were not just standing by and watching.

They will eliminate any clones that try to escape, preventing Muzan Kibutsuji from getting away.

Soon, all of Muzan Kibutsuji's clones were wiped out by Ji Lin and the others. In the end, Muzan Kibutsuji's main body was also destroyed by Ji Lin. Watching Muzan Kibutsuji scream as he turned to ashes, everyone had a somewhat incredulous expression. After all, Muzan Kibutsuji, as a being who was like the original demon ancestor, died in such a wretched manner, making everyone wonder if Muzan Kibutsuji was faking his death or something.

Ji Lin looked at the system panel in front of her and breathed a sigh of relief. It seemed that Muzan Kibutsuji's clone had not escaped. This allowed Ji Lin to assure Shinobu and the others that Muzan Kibutsuji was dead.

Upon hearing Ji Lin's words, many people cheered. At the command post, Ubuyashiki Kagaya watched the cheering crowd on the monitor and smiled with relief. Just after Kibutsuji Muzan died, Ubuyashiki Kagaya felt something disappear from his body.

The trainees behind Kagaya Ubuyashiki seemed to have lost a heavy burden.

Back in the Infinity Castle, Tanjiro saw Muzan Kibutsuji reduced to ashes, and his hatred vanished. Although he hadn't killed Muzan Kibutsuji himself, Tanjiro felt it was enough.

The only goal now is to turn his sister Nezuko back into a human. Tanjiro has heard from Tamayo at the Butterfly Mansion that she has developed a formula for a drug that can turn demons back into humans. All that's left to do now is wait.

After defeating Muzan Kibutsuji, the Demon Slayer Corps also eliminated Nakime, after which the Infinity Castle disappeared from the world of Demon Slayer.

Chapter 506 [Ling: Hello, Aunt Ji Lin~]

After Yuhaka and the others dealt with Muzan Kibutsuji, they held a special celebration banquet at the Demon Slayer Corps headquarters to commemorate the disappearance of the progenitor of demons. With the source of everything gone, the demons existing in this world will soon be eliminated.

Yuhaka and the others returned to their old home at the Meru Cat Restaurant after attending a banquet at the Demon Slayer Corps headquarters.

.................................. ............................

In Yuhaka and Jilin's room, Jilin, who was lying on the bed, felt something pressing down on her. Then, Jilin opened her eyes and looked at herself and saw Yuhaka drooling on her chest.

"Ugh... Master Youyou, please don't drool on my chest..."

As she spoke, Ji Lin flipped Yuhaka to the side, then picked up a tissue from the bedside table and wiped away the drool that Yuhaka had left on her chest. Afterward, Ji Lin straightened her nightgown, scratched her slightly messy long black hair, and got off the bed. When Ji Lin's two delicate white feet touched the floor, she felt her legs go weak and she almost fell to the ground.

"Hiss... Master Youyou is probably getting more and more energetic..."

Ji Lin, taking a deep breath, rubbed her slender waist and looked at Yuhaka lying on the bed in a "Tai" shape. She couldn't help but wonder if she should find herself another sister, since she couldn't handle it all by herself.

At this moment, Xilin, who was still sleeping in, suddenly shuddered, as if she sensed something bad.

After leaving the room, Ji Lin headed towards the bathroom. After throwing her slightly wrinkled, thin nightgown into the basket, Ji Lin turned on the shower to clean off the "traces" left by Yuhaka on her body. After showering, she changed into clean underwear and clothes, then brushed her teeth, washed her face, and combed her hair.

After finishing these tasks, Ji Lin went to the kitchen to make breakfast.

The breakfast was simple: two poached eggs, two sausages, bacon, three cherry tomatoes, and two slices of toast—a typical Western breakfast.

After preparing breakfast, Ji Lin went to wake up the others. After waking up the others, everyone gathered in the living room to eat breakfast. Yuhaka was woken up by Ji Lin and then dragged by his tail to the bathroom to give Yuhaka a good bath.

After all, there were traces left on Yuhaka's body from last night, so Yuhaka should at least get a proper bath first.

After giving Yuhaka a bath, Ji Lin brushed Yuhaka's teeth and washed his face. After giving Yuhaka's soft little face a good massage with a hot towel, Ji Lin took Yuhaka to have breakfast.

Located at the dining table in the living room of Yhaka's house, Bronya, who had just finished breakfast, was playing a game when she saw Yhaka being dragged over by Ji Lin. She immediately broke out in a cold sweat. Although this was a common occurrence in Yhaka's house, no matter how many times Bronya saw it, she always felt a strange feeling.

However, Bronya didn't complain about her "parents" being like this.

After everyone finished breakfast, Kanna went to school, while Kuro sat on the sofa playing games as usual. As one of the creator gods of another world, Kuro has now completely become a gamer. Sirin was called to wash the dishes, since it was her turn to do so today.

Yuhaka and Bronya went to pick up Rin, who had been left to fend for herself with Mishiore.

After passing through the doors of the Meru Cat Restaurant and arriving in the world of Mishiore, Yuhaka and the others headed towards the palace where Mishiore was located.

Upon arriving at the Mishiore Palace, Yuhaka and her companions encountered Rigota, who was carrying a stack of books. Rigota peeked out from behind the tall pile of books, looking at Yuhaka and her companions with a surprised expression, and said:

"Oh my! Hero, and Sister Ji Lin and Little Bronya? You've arrived~"

After greeting Rigota, Yuhaka and the others asked about Rin's location. Upon hearing their question, Rigota replied to them:

"Are you talking about Miss Ling? If so, she's with Lord Dargion right now."

Upon hearing Rigota's words, Ji Lin, who was standing to the side, thought of the sword knight who was known as the "strongest on the continent." However, Ji Lin didn't quite understand why Ling would go there.

After saying goodbye to Rigota, Yuhaka and the others went to the cabin where Dalgion lived. Soon, they arrived at Dalgion's residence and saw Bell petting a dog in the yard.

Bell, who was petting the dog, saw Bronya approaching and stood up, waving to her and saying:

"Bronya~ Over here~"

Bronya looked at the energetic Rin and didn't know what to say. Although she was going to bring Rin back to the Meru Cat Restaurant when she returned yesterday, she accidentally forgot about Rin when she went home after the banquet at the Demon Slayer Corps headquarters. It wasn't until this morning when Ji Lin asked her about Rin that Bronya remembered that a fox had forgotten about her.

Ling trotted over to Bronya with a bunch of dogs and said:

"Bronya, you're finally back! I've been waiting here for ages. By the way, Bronya, have you finished taking care of things over there?"
