Two days later.
In the courtyard that was once desolate.
Shirakawa had completely grown into a giant flesh-and-blood tree.
The tree was covered with countless eyes and human heads.
This scene, just by looking at it, was enough to make one's scalp tingle.
And it was precisely at this moment.
The courtyard's gate was pushed open.
A group of Hashira, led by Ubuyashiki Kagaya, arrived here.
Since learning of Muzan's death.
Ubuyashiki Kagaya had guessed Shirakawa's intentions.
To prevent Shirakawa from becoming another Muzan.
Ubuyashiki Kagaya simply brought the many Hashira of the Demon Slayer Corps to Kyoto.
Intending to see how the aftermath of the situation would unfold.
And when Ubuyashiki Kagaya entered the courtyard.
Seeing Shirakawa transformed into a flesh-and-blood tree.
His heart sank.
“This, this wouldn’t be Mr. Shirakawa, would it?”
“As expected, it’s exactly as I guessed.”
“He really did turn himself into a demon.”
Ubuyashiki Kagaya’s tone was very complex.
He was unsure how to deal with Shirakawa’s transformation.
From a standpoint of reason.
Shirakawa was a benefactor to the Demon Slayer Corps, to the Ubuyashiki family.
He had saved them, essentially recreated them.
But from a standpoint of justice.
To prevent another world-ending Demon King from emerging in the future.
He should be eliminating Shirakawa, this hidden danger, right now.
In any case, Ubuyashiki Kagaya was very conflicted now.
He didn't know what to do.
In the end, Ubuyashiki Kagaya looked at Kasugai Shizuka.
“Shizuka-san, how should we handle this situation?”
Unable to make a decision, Ubuyashiki Kagaya could only ask Kasugai Shizuka’s opinion.
And Kasugai Shizuka, looking at Shirakawa transformed into a flesh-and-blood tree.
Was indeed a bit surprised.
It seemed she hadn’t expected Shirakawa’s so-called “evolution” to be so drastic.
However, as soon as she recalled Shirakawa’s words to her.
That no matter how drastic the change.
He could remain himself.
Kasugai Shizuka relaxed.
In Kasugai Shizuka’s heart.
Shirakawa was already omnipotent.
Someone like him, if he said he could change back, he could definitely change back.
So, Kasugai Shizuka said: “Shirakawa always does things in moderation.”
“He will never do anything reckless.”
“Since he chose to become a demon, then I believe he will be able to change back.”
Her implication was to tell Ubuyashiki Kagaya not to interfere.
Just let Shirakawa do his thing.
Hearing Kasugai Shizuka say this.
Ubuyashiki Kagaya could only refrain from doing anything for now.
After all, Shirakawa’s prestige in the Demon Slayer Corps was simply too high.
Unless Shirakawa started killing indiscriminately, truly went mad.
Otherwise, even if Ubuyashiki Kagaya was the head of the Demon Slayer Corps.
He wouldn’t be able to have those Hashira draw their swords against Shirakawa.
Which one of those Demon Slayer Hashira hadn’t been taught by Shirakawa?
In this situation.
Unless absolutely necessary, who would truly draw their sword against Shirakawa?
Of course, Ubuyashiki Kagaya didn’t leave.
He stayed with the others, keeping watch.
Ultimately.
He was still uneasy.
Just in case, just in case.
If Shirakawa truly became a Demon King even more hateful than Muzan.
Then, Ubuyashiki Kagaya would be able to act immediately, with everyone, to eliminate this threat.
This wasn’t being ungrateful.
It was for the sake of all living beings.
Thankfully, the situation that Ubuyashiki Kagaya worried about most, didn’t happen.
..
After guarding the flesh-and-blood tree for three days.
This giant flesh-and-blood tree began to wither continuously.
In the end, it turned into rock, completely losing its fleshly texture.
This change naturally attracted the attention of others.
Seeing this change.
Ubuyashiki Kagaya was a bit dumbfounded.
“Is this, is the transformation complete, or has something gone wrong?”
No one answered his question.
Because soon, with a cracking sound.
The entire giant flesh-and-blood tree began to crack continuously.
In the end, all that was left was a pile of dust.
And within the dust, Shirakawa’s figure emerged.
Shirakawa at this time, was not much different from his usual appearance.
Only his features were slightly more refined, his physique better.
Other than that, there wasn’t much change.
Unlike Muzan.
He had completely become a monster.
.....
After the transformation was complete.
Shirakawa opened his eyes.
The first thing he saw was Kasugai Shizuka running towards him.
Shirakawa reached out and caught Kasugai Shizuka.
After rewarding her thoroughly.
Shirakawa put Kasugai Shizuka down.
Then looked at Ubuyashiki Kagaya and the others.
Smiling, he explained: “I made you worry.”
“This transformation took longer than I expected.”
“But it’s fine now, I’ve completely finished transforming.”
After absorbing Muzan’s flesh.
Shirakawa had fallen into a state of transformation.
Because the amount of Demon King’s blood was simply too much.
It caused Shirakawa to be unable to absorb it all at once.
This led to his demonization phenomenon.
Fortunately, after a few days of digestion.
Shirakawa had completely absorbed the Demon King’s blood.
And it was completely without side effects.
Simply put.
Shirakawa had obtained all the benefits of becoming a demon.
But hadn’t accepted any of the drawbacks of becoming a demon.
His essence was still human.
And hadn’t become anything else, anything strange.
It was just that the process was a bit painful.
After all, it was a change at the most basic level of genes.
Its pain was no less than being hit by a road roller.
But it was all worth it.
Because Shirakawa now.
Was already far stronger than before.
.....
First, his physique.
Shirakawa’s physique now.
Had evolved to an absurd level.
Several times stronger than before.
And this, was only one aspect.
On the other hand.
After completely becoming a demon.
Shirakawa had awakened his own Blood Demon Art!
Blood Demon Art, originates from one’s strongest desire when they become a demon.
And Shirakawa’s desire was naturally to make himself more perfect.
Therefore, his Blood Demon Art was related to evolution.
Its full name was: “Adaptive Evolution”!
