Crossover Anime: Starting with Adopting the Homeless Melon God

"He has an extremely strong competitive spirit and is determined to catch up with and surpass his younger brother Yoriichi Tsugikuni. However, due to his lack of talent, he took the initiative to find Muzan and transform into a demon, hoping to borrow the long lifespan of a demon to continue his training and one day break through."

"He created the Moon Breathing, which corresponds to the Sun Breathing, and is only one step away from reaching Yoriichi Tsugikuni's level. At that time, even if his neck was cut off by the Nichirin Blade, he would no longer be able to be killed. With the current strength of the Pillars, even if we include Gyomei Himejima and all the Pillars attack together, they would not be his match."

"His weakness is that he has too much pride and is afraid to face his ugly appearance after he becomes a demon."

"Upper Moon Two, Doma, the one Kanae met last night, is the leader of the secret cult 'Eternal Bliss'. He was born without human emotions and his ability is to control ice."

"To kill him, it would take at least the combined efforts of Himejima Gyomei and Kanae. Of course, if either of them were to activate their Demon Slayer Mark, they could kill Dio Doma single-handedly."

"Upper Moon Three, Akaza, was a martial arts prodigy in his human days. Because his master and lover were killed by a rival kendo dojo, he massacred them. Later, Muzan took a liking to him and forcibly twisted his will, turning him into a demon."

"His strength is similar to that of Himejima Gyomei, and they can almost die together in a life-or-death battle. However, he has great potential. If you can't kill him in one go, you only need to go through one or two evenly matched life-or-death battles to reach a level of strength close to that of Kokushibo."

"Upper limit four"

"."

"In addition, Kibutsuji Muzan's personal maid, Nakime, also possesses power comparable to the Upper Moon, and also has the powerful ability of teleportation."

After Kitagawa Yu finished introducing the information about Upper Moon, everyone in the reception room, except for Elena who remained calm, couldn't help but frown and show a solemn expression.

Before this, although they had always known that the Upper Crescent Moon was very strong, they did not have a concrete concept of it.

It's unbelievable that Kokushibo could be so powerful as to take on all the Pillars single-handedly. Even more unbelievable is that even the weakest Upper Moon Six is ​​comparable to Kanae. Kanae would have to pay a heavy price to kill him, and her fighting strength would likely plummet afterward.

Most importantly, Muzan Kibutsuji was able to command so many demons and make them submit to him, which means that in addition to the suppression of bloodlines, his own strength must also be very strong, at least stronger than Kokushibo.

Add to that a super support character with teleportation abilities.

Their Demon Slayer Corps has absolutely no chance of winning!

In fact, this is indeed the case.

At the very beginning of the main story, on paper, Muzan Kibutsuji's side was at least four or five times stronger than the Demon Slayer Corps. If they were to fight head-on, it would be like a dragon charging in and there was no way they could lose.

But Muzan Kibutsuji just likes to send his subordinates to their deaths one by one. And then three main characters suddenly appeared on the Demon Slayer Corps' side, one of whom is the successor of the Sun Breathing technique.

This finally turned the tide of the battle.

Even so, the Demon Slayer Corps paid an extremely heavy price in the process of eliminating Muzan. Apart from the Wind Pillar Sanemi Shinazugawa, the Water Pillar Giyu Tomioka and the Sound Pillar Tengen Uzui, who survived despite being crippled, all six other Pillars died.

This is why Demon Slayer is often jokingly referred to as "Pillar Slayer."

Even with the help of Kitagawa Yu and the other two, Ubuyashiki Kagaya, who has yet to see them fight and is unsure of their combat abilities, still feels immense pressure.

"By the way, what are the markings and crimson blades that Kitagawa-san just mentioned?"

"The marks are a special state. You need to first cultivate your breathing technique to the level of 'total concentration and constant balance,' and then, while maintaining the breathing technique, raise your body temperature to 39 degrees Celsius and increase your heart rate to over 200 beats per minute. At this time, flame-shaped red marks will appear on your face."

"This marking can greatly enhance physical attributes once again. At the same time, when gripping the Nichirin Blade tightly, it can unleash the solar power within the crimson iron sand used to forge the Nichirin Blade, causing the Nichirin Blade to enter its crimson state."

"The Nichirin Blade in its Crimson Blade form can greatly suppress the self-healing ability of demons. Apart from Muzan, other demons, even a powerful Upper Moon One like Kokushibo, would take several minutes to recover from being cut by the Crimson Blade."

"However, the power of the markings comes from burning lifespan, and once activated, there are only a few years left to live."

"Can't the mark be turned off once it's activated?" Kagaya Ubuyashiki asked, frowning.

"Probably not, at least I don't know how to turn off the markings." Kitagawa Yu shrugged regretfully.

"However, you don't actually need to activate your Demon Slayer Marks. There's an even simpler way to defeat Muzan Kibutsuji!"

"What method?" Shinobu Kocho, who was the most impatient, asked immediately.

"It's very simple. Just pray sincerely to the god I serve, just like Shinobu did before. The more people pray, the better. The more sincere and intense the prayers, the more powerful the god will grant me."

Chapter 117 The First Batch of Testers

Kitagawa Yu smiled slightly and said confidently, "I don't need too many. Just a dozen or so pure-hearted supplicants like Shinobu who sincerely pray will be granted enough power by the gods so that I can lock onto Muzan Kibutsuji and kill him."

"With Muzan Kibutsuji dead, all the demons transformed from his blood will also die. This world will no longer be threatened by demons."

Although they had already decided to help the Demon Slayer Corps defeat Muzan Kibutsuji and save Shinobu Kocho and the others who would sacrifice themselves in the future.

However, if given the opportunity, Kitagawa Yu wouldn't mind harvesting a wave of wish power.

After all, the Demon Slayer Corps should have many pure-hearted individuals who meet the system's requirements.

Kagaya Ubuyashiki looked into his eyes, thought for only two seconds, and then smiled and agreed to his proposal.

"Most of the children in the Demon Slayer Corps have had relatives killed by demons, and they all harbor intense hatred for Muzan Kibutsuji, hoping to destroy him. As for whether they can reach the standard of pure heart that Kitagawa-san spoke of—"

"Just try it once."

Having made up his mind, Kagaya Ubuyashiki immediately took action, beginning to summon the swordsmen he felt met the standards back to headquarters.

At the same time, he brought his family along, including Kanae, Shinobu Kocho, and Kanao and Aoi Kanzaki, whom Kitagawa Yu specifically mentioned, as the first batch of testers.

then

Kitagawa Yu sat cross-legged on the cushion, looking at the entire column of system messages on the system screen in front of him, and he could hardly hide the smile on his lips.

"One, two, three, four, five, six, seven, eight wishes? Not bad, not bad!"

"I didn't expect that Shinobu's wish would actually come true."

"But why didn't Teruya Ubuyashiki and his two younger sisters succeed in their prayers? Was it because they were too young and their hatred for Muzan Kibutsuji wasn't deep enough?"

"But Ubuyashiki Hinai is only 7 years old. How did their wishes come true?"

"And Kanao's wish didn't come true either. But that makes sense, she was bought from human traffickers by Kanae and Shinobu, and none of her relatives died at the hands of demons."

This time, Kitagawa Yu received eight wishes for the first time ever. If he fulfills them, he will gain at least several dozen wish powers.

The thought of it fueled Kitagawa Yu's even greater motivation to defeat Kibutsuji Muzan.

Meanwhile, far away in Tokyo, in a Western-style garden villa covering several hundred square meters, Muzan, disguised as a child, finally noticed that Nakime was acting strangely.

"Nakome! Nakome, what are you doing? Answer me!"

With a gloomy expression, Muzan Kibutsuji called out in his mind, and the few test tubes of medicine he was holding in his hand, which he had originally intended to take back to the Infinity Castle for experiments, had already been unconsciously crushed into powder.

This is how it all started. He used his ability to manipulate cellular-level transformations to have multiple identities in human society, and used this to collect various technologies and materials in order to develop a potion that would make him immune to sunlight damage without relying on the legendary Blue Spider Lily.

Unfortunately, his talent in scientific research is nowhere near that of Snake, and he has been researching for nearly a thousand years without finding any answers.

However, he felt that his research was very valuable and that it would be easy to expose if left outside, so after subduing Nakime, he moved his base to the safer Infinity Castle.

That day, he had just finished another round of experiments and was preparing to bring the finished product back to Infinite City.

But then he suddenly realized that no matter how he called out to Nakime, there was no response.

Through his connection to his own blood, he could barely sense the location of a target, initiate a telepathic conversation with it, and even perceive whether the target was still alive.

However, he didn't know the specific state of the target.

Nakime was just a psychopathic killer, not a martial arts master with a particularly strong will or anything like that. Under Kitagawa Yu's painful curse, she couldn't even speak, and the only reason she could maintain her consciousness was because of the protective power of the curse itself.

Moreover, her teleportation spell requires the vibration of her beloved pipa to activate.

Her whole body was convulsing and contorting, and she was completely unable to control her body to make any movements. Even if Muzan Kibutsuji screamed until his throat was hoarse, there was nothing she could do.

But Muzan Kibutsuji didn't know any of this.

With a dark personality, he always assumed people were malicious; otherwise, he wouldn't have killed the doctor who treated him.

No matter how much he called out, there was no response. His first thought was that Nakime had betrayed him, because something similar had happened to him many years ago.

Unconsciously, Muzan Kibutsuji thought of Tamayo, and a cold glint flashed in his eyes.

Tamayo was originally a demon he personally transformed with his own blood, but later, through her outstanding medical skills and hundreds of years of research, she found a way to sever his control and senses, and successfully betrayed and escaped from his side.

Although he can still sense Nakime's location and control her to kill her with the backlash of the demon blood, if Nakime really doesn't know why she fell into Tamayo's hands, she will eventually break free from his control.

"Nakome must not fall into the hands of anyone else!"

This is his bottom line.

He usually felt how useful teleportation ability users were, but he realized how troublesome they would be if they became his enemies.

But Nakime's abilities are extremely rare.

It's no exaggeration to say that Nakime was even more important to him than Doma and Kokushibo.

Even with his ruthlessness, he couldn't bring himself to do it before confirming the facts.

"The location of Infinite City hasn't changed. Let's go check it out first!"

With a flash, Muzan Kibutsuji left the garden villa, then manipulated his body to extend hundreds of tentacles that condensed into a drill that enveloped his entire body before plunging into the ground.

It has to be said that he is truly strong as the Demon King. Even without his reawakening during the final battle of the main story, his strength is still terrifying.

In less than half an hour, he dug out a five-kilometer-long tunnel that went three hundred meters underground and entered the Infinite City. Then, in a room extending from the Infinite City, he found Nakime, whose consciousness was perfectly clear, but whose body and soul were in uncontrollable pain.

Then three big question marks appeared above my head.

"She wasn't captured, nor was she controlled? Then why... wait, her body seems to be trembling, her eyes are hissing—"

Muzan cautiously refrained from approaching directly, instead sticking out two slender tentacles from the doorway. He parted the long hair on Nakime's face and looked at the single eye that now occupied most of Nakime's face after she became a demon.

At this moment, even he, who had lived for over a thousand years and had personally caused countless tragedies, was somewhat startled.

Pain, despair, and a desire to die quickly!

He had seen this emotion in the eyes of many people before, but he had never seen it as intense as the one in Nakime's eyes.

He didn't know what terrifying thing could make Nakime look like that.

But he knew that even the methods he had spent a lot of time researching to torture his enemies probably wouldn't be able to make Nakime show such a look in her eyes.

At this moment, Muzan Kibutsuji's expression turned icy, his vigilance reaching its peak, his eyes darting around rapidly, scanning every corner of his surroundings.

However, the attack he feared did not occur until several minutes later.

"The enemy isn't here? Then how did Nakime get hit?"

After pondering for a moment, Muzan Kibutsuji suddenly thought of Nakime's other ability—eyeball clones.

Nakime can create eye-shaped clones that share vision with her main body. Combined with her teleportation ability, she can leave her main body in the Infinity Castle and send her eyeballs out to observe the outside world.

"Could it be that the enemy possesses a special attack method, capable of attacking Nakime's main body through eye-shaped clones?"

Muzan Kibutsuji opened his mouth, intending to ask Nakime a question, but upon seeing Nakime's pained expression, her mind filled with nothing but thoughts of dying, he could only helplessly abandon the idea.

The most important thing now is how to save Nakime.

As long as Nakime hasn't betrayed him, he's unwilling to give her up so easily.
