Demon Slayer: Starting with the Kingdom

It means to be a nanny.

At first, Mitsuha was actually reluctant to go.

It's not that Mitsuha doesn't want to be a babysitter; the main reason is that among the Twelve Demon Moons, she is considered a "dove."

Unlike Muzan, who is determined to crush the Demon Slayer Corps like ants, Mitsuha, who is a "dove," actually agrees with the "symbiotic" relationship between demons and demon slayers.

After all, in her view, only if the Demon Slayer Corps continues to exist can it give the gods in heaven the feeling that "He has not lost yet, and His efforts are still worthwhile."

If the Demon Slayer Corps is completely wiped out and the Ubuyashiki family's bloodline is completely severed, who knows what kind of trouble that unreliable god will cause...

Therefore, rather than wiping out the Demon Slayer Corps and then facing a new threat of unknown strength, it is better to...

Mitsuha felt that maintaining the existence of this half-dead Demon Slayer Corps, thereby constantly tying down the energy of the gods in the heavens, might be a more suitable option.

Unfortunately, Muzan-sama did not agree with her theory.

Not only did she disagree, but every time Mitsuha said that, Muzan would give her a severe scolding, saying, "Don't always talk nonsense, you should believe in science..."

Sigh, there's nothing I can do about it; having a boss who's overly superstitious about science is just like that...

Of course, despite their different stances, Mitsuha always complains about the tasks Muzan assigns her, but she still does her job seriously.

"Holy Maiden, come quick, come quick! This is it!"

"Please, Doma, stop calling me that weird name. Don't you feel ashamed at all...?"

In the dead of night, in a deserted mountain, Mitsuha, who had been teleported there by Nakime along with Doma, felt ashamed for the first time in her life.

She couldn't understand why the ghost next to her didn't have any sense of shame.

How could he utter such a shameful term so calmly?

Wait a minute... without changing his expression?

As if suddenly realizing something, Mitsuha frowned subconsciously.

All the changes in expression that Doma had shown in front of her were now flashing through Mitsuha's mind.

She finally realized that something had been subtly strange in her heart ever since she first met Douma—

All of this guy's emotional expressions seem to be limited to changes in his body movements and facial features.

Normally, when a person feels extremely excited, in addition to exhibiting exaggerated reactions such as waving their arms and legs and grinning, they will also show other signs of excitement.

There should also be some subtle, spontaneous bodily reactions, such as flushing of the cheeks, increased heart rate, and changes in breathing rhythm, etc.

However, Mitsuha seems to completely lack these qualities in Doma.

Even when he first met her in the Infinite City and excitedly jumped up to call her "Holy Maiden," Mitsuha never saw any similar reaction on his face.

It's as if all those changes in his expression didn't come from his true self, but were merely a kind of...performance?

Seeing Doma waving his arms and skipping towards the Demon Slayer Corps' base, Mitsuha, who had previously had no interest in him, suddenly became very interested.

With the Transparent World open, Mitsuha could clearly see that Doma's heartbeat and blood flow were perfectly stable, without any change, which was completely inconsistent with the excitement he was showing at the moment.

This is so interesting.

You didn't actually feel that way, but you're forcing yourself to act like it... Little one, what's your reason for doing this?

And, are you simply slow to react and trying to fake it, or are you truly devoid of emotion?

Mitsuha decided to observe carefully.

"Your Holiness, we've arrived. Those demon hunters must be inside by now."

"Very well, Knight Doma, the rest is up to you. Just don't let those demon slayers come and hurt me, okay?"

The two demons unexpectedly clicked and cooperated quite well with Doma in his role-playing. Mitsuha, smiling, found a place to sit down and prepared to watch Doma's next performance.

Now, more than two hundred years have passed since that legendary Warring States period.

The Demon Slayer Corps, once incredibly powerful in its time, has now fallen to the sidelines after losing its elder brother Yoriichi and suffering multiple annihilations.

Although the description is somewhat insulting, it is indeed true.

The Demon Slayer Corps of today has neither the Demon Slayer Mark nor the Crimson Blade, and they have no idea what the Transparent World is.

The repeated breaks in the lineage have even led these demon hunters to forget what the "Initial Breathing Technique" actually is...

We only know that it exists, but we don't know what it contains.

Chapter 110 She took another step closer to God

For these demon hunters today, everything that happened during the Warring States period has become a legend in the truest sense.

Even without using Blood Demon Art, Mitsuha could easily kill all of these demon slayers by simply picking up a tree branch from the ground.

But even such a demon slayer is still capable of slaying an Upper Moon demon, even if it is only the weakest Upper Moon Six.

The Twelve Demon Moons have truly fallen into depravity; no wonder Lord Muzan was so angry…

Fortunately, Doma doesn't seem to belong to this category?

Although he has only recently been promoted to Upper Moon, Doma's strength is not to be underestimated.

Inside the Demon Slayer Corps' base, Doma single-handedly stormed in, and despite being surrounded by a large number of demon slayers led by a Pillar, he handled the situation with ease.

He even had the energy to toy with those few outstanding female demon hunters.

Doma's Blood Demon Art is quite unique; he can condense his own blood into ice crystal powder, which he then disperses and controls using the pair of iron fans in his hands.

According to Doma's idea, these ice crystals can either condense into simple ice pillars and ice mist, or transform into ice puppets and giant ice bodhisattvas with autonomous combat capabilities to attack, making their attack methods extremely comprehensive.

Even worse, his ice crystals can even quietly enter the lungs of the demon hunters with their breathing, causing irreversible damage to their alveoli.

This is a devastating blow to demon hunters who rely on breathing techniques.

Like Mitsuha, Doma's Blood Demon Art is also one that is extremely lethal to humans.

A natural nemesis of demon hunters.

Of course, these things have nothing to do with Mitsuha. It's Muzan's job to evaluate Doma. She's only curious about Doma's reaction during the battle.

Just like the personality that Doma deliberately displays, he is also the type who is "talkative and playful" when fighting.

Even if he could overwhelm his opponent in terms of combat power, he would not do something like one-hit kill. In fact, if his opponent wanted to chat, he would even stop and chat with him for a bit.

But just as Mitsuha had predicted, under the Transparent World, no matter what emotions Doma displayed, there were no corresponding changes in the flow of his blood or his heartbeat.

This guy is really putting on an act the whole time.

So why would this guy do something so pointless?

"You demon! Die!"

Just as Mitsuha was deep in thought, a demon hunter on the outskirts of the camp finally noticed her, raised his knife, roared, and charged at her to cut her down.

"Don't bother me, there's a ghost inside, go and chop him up."

"Oh, okay!"

Too lazy to bother with him, Mitsuha, who was deep in thought, simply raised her hand and used Blood Demon Art to alter the demon slayer's mind. Immediately, he turned around and rushed towards Doma in the camp.

The scene was very strange, but the ghost hunter was completely unaware of anything unusual.

As time passed, Mitsuha's Blood Demon Art naturally underwent further development over a long period of accumulation.

Especially after nearly a hundred years ago, when she was almost killed by Tamayo and that generation of Demon Slayer Corps, under the threat of death, her Blood Demon Art, which had been stagnant for a long time, made unprecedented progress.

In the past, the abilities of causal manipulation and fate rewriting were always used separately.

One principle is that there must be a cause for an effect to occur; without a cause, there can be no effect.

The other is completely unrelated to cause and effect, focusing entirely on the replication of a specific phenomenon, but also confined to its own domain.

Now, Mitsuba is able to properly combine and use these two abilities together.

Like that demon hunter just now, his original intention was to "swing his sword at Mitsuba".

In the past, Mitsuha could at most influence his attack moves or subconsciously order him to commit suicide with his sword, but she could never make him turn back and run to kill Doma.

Because the process was so long, the demon hunter had ample time to react and realize Mitsuba's mind manipulation while turning around and running back.

The truth is, this person was completely unaware that he was being manipulated, and simply followed Mitsuha's instructions to obediently go back and kill Doma.

the reason is simple.

In that instant, Mitsuba directly overwrote the cause and effect in the demon slayer's mind, forcibly creating a cause and effect of "I want to go back and kill Doma".

In this way, the cause-and-effect relationship of "I want to cut down Mitsuba" that originally existed in his mind was overwritten, and this reality was finally achieved.

That's right, we use overwriting to forcibly create a cause and effect that did not originally exist, and let it replace the original cause and effect to become reality.

Mitsuha is now able to do that.

She named this new ability "Causal Overwriting".

This ability may sound unremarkable, but upon closer inspection, it is actually quite terrifying.

This ability to forcibly distort reality can be described, to put it somewhat dramatically, as—

Mitsuha is one step closer to becoming a "god".

Of course, her new ability also has significant limitations.

Besides being able to work only within her own domain, the "causality" that Mitsuha can create also depends entirely on her own perception and must conform to the corresponding logic.

She cannot create any causal relationships that she has not seen or that are beyond her comprehension.

Take, for example, the blue spider lily that Lord Muzan longed for.

Mitsuha had never seen this flower before, nor did she understand its principles. Therefore, she was completely unable to forcibly create this mysterious flower using her ability to overwrite cause and effect.

The limits of her abilities depend on the limits of her own cognition.

Even with these limitations, her new ability is still incredibly powerful.

Several years ago, in order to test the limits of her new abilities, Mitsuha conducted a series of experiments.

She first randomly picked a farmer on the road and used her ability to overwrite cause and effect to create a cause and effect for the farmer that he "always carries a magnificent samurai sword".

Initially, the attempt failed.

This farmer came from a poor family and had never encountered any benefactors, nor had any of his ancestors been prominent figures.

It's illogical that a "magnificent samurai sword" would exist in his home.

Immediately afterwards, Mitsuha began to repeatedly rewrite and adjust the cause and effect on this farmer.

First, Mitsuha changed his birth to a decent one, adding the cause and effect that "at the time of his birth, his parents dug up the treasures buried by their ancestors in the backyard of their home."

Thus, the image of the farmer began to change in Mitsuha's eyes.

His physique was no longer thin and weak, but rather slightly plump, and his clothes were no longer tattered and worn, but replaced with cotton clothes that only a few wealthy farmers could afford.

Chapter 111 Let's go for a stroll in the flower market together (Bonus Chapter)

Next, Mitsuha added another cause and effect to the farmer's childhood: "I want to become a blacksmith when I grow up."

As a result, the farmer's physique became stronger, especially the muscles in his arms and abdomen, which became particularly well-developed.

But the farmer still didn't have a fancy samurai sword.

The cause and effect that Mitsuha initially created has not yet been realized.

Because he lacks sufficient wealth, he logically still lacks the ability to forge a magnificent samurai sword.

So, Mitsuha added the final crucial causal link for the farmer—

At the age of twenty, his exceptional forging skills were recognized by a daimyo, who commissioned him to forge swords for him for decades. Finally, in his old age, he returned home in glory with a magnificent samurai sword gifted to him by the same daimyo.

At this point, all the necessary conditions have been met, and the logical chain is completely complete.

Finally, in the farmer's hand appeared the magnificent samurai sword that Mitsuha had longed to see.

Yes, it appeared out of thin air, just like that, all of a sudden.

Through this entire process of multiple tests, Mitsuha also thoroughly understood the effects of her new ability.

What she didn't mention before was that the money initially buried in the farmer's backyard in this experiment didn't actually appear out of thin air; she buried it secretly...

This is the biggest limitation of her new ability.
