Turning the Mirokuji Kirigiri into a girl as a Yoto-hime was an idea that had been born the first moment Mahito saw it.
As Mahito cultivated her into a true Tsukumogami, this idea grew with uncontrollable madness.
But unfortunately, Mahito tried for a long time without any progress.
He specifically consulted Kenjaku about it.
Kenjaku didn't flatly deny it; he said the combination of the Construction Technique and Idle Transfiguration contained too many possibilities, and it wasn't an impossible task.
However, such a thing was truly the first of its kind since the beginning of the Jujutsu World.
It was completely uncharted territory, and no Jujutsu Sorcerer had ever researched it.
Research into Half-Cursed Spirits at least had a theory behind it.
Kenjaku had tried cultivating them in the past.
In other words, although no Half-Cursed Spirit actually appeared in the original timeline, the theory was complete and not without foundation.
But this matter didn't even have a basic theory; even with Kenjaku's abilities, he was helpless.
Kenjaku introduced Mahito to someone: the ancient sorcerer Yorozu.
According to Kenjaku, during his thousand years of wandering, he had seen the most outstanding Construction Sorcerers of every era.
Yet despite a millennium of seeing all sorts of top-tier Construction Sorcerers, Yorozu remained in a league of her own.
If they had Yorozu's help, combined with Mahito's unique Idle Transfiguration, even humanizing a Tsukumogami—something never before seen in the Jujutsu World—might be possible.
Or so Kenjaku had said.
And now, Yorozu was right before Mahito's eyes.
Her answer was—
"It's impossible."
Tsumiki Fushiguro asserted, "Give up, Mahito."
Because they weren't sure who had placed the barrier covering Tsumiki Fushiguro, Mahito and the others didn't dare stay at the hospital for long.
After confirming that Tsumiki Fushiguro was willing to temporarily follow Mahito, they returned directly to their base.
And now, Tsumiki Fushiguro was in the room specifically set aside for Kirigiri.
She was carefully observing this Tsukumogami, which was created using a replica of the ancient sword Futsu-no-Mitama as a base.
She took Kirigiri off the sword rack and gently drew her from the scabbard.
The straight-edged greatsword, over two meters in length, emitted a light metallic ring as it was drawn.
She stared at this ancient sword Tsukumogami and marveled.
"The cultivation is outstanding, and its spirituality is perfect."
"If you hadn't explicitly told me that Mirokuji's cultivation time didn't exceed two months, I would have thought I was witnessing a Tsukumogami of over three hundred years."
"This is a beautiful girl."
"I can feel her quietness and elegance, like a white swan floating silently on the water's surface."
"Just by looking at her, I understand that you love her very much."
Tsumiki Fushiguro looked up at Mahito and said with a frown.
"Repairing her is simple; two days is enough."
"I don't understand why you want to humanize her."
"Is there any meaning to it?"
Mahito thought seriously.
"Because it's cool."
Tsumiki Fushiguro's lip twitched.
"I hope you're joking."
"I'm not joking, I'm very serious," Mahito declared loudly.
"A man should love Yoto-hime!"
On the way over, Tsumiki Fushiguro had learned that Sadatsuna Ashiya was also here.
Originally, she intended to visit Sadatsuna Ashiya first.
A thousand years ago, the relationship between them was very strange.
Not that it was Sadatsuna Ashiya's fault; it was entirely due to Yorozu's own antics.
Now, Tsumiki Fushiguro naturally didn't want such a strange relationship.
She hoped to have an old friend for normal interaction.
Well, in Tsumiki Fushiguro's eyes, Kenjaku didn't count as a friend at all.
She trusted Sadatsuna Ashiya much more than Kenjaku.
But at this time, Sadatsuna Ashiya, Hanami, and Dagon were teaching five newborn intelligent Cursed Spirits, so they hadn't come over yet.
Kenjaku went to call them personally, and Mahito first brought Tsumiki Fushiguro here to see Kirigiri.
She thought that simply repairing Kirigiri would count as repaying Mahito's kindness for waking her up, and she was indeed confident in this.
She was the strongest Construction Sorcerer of the past millennium, as certified by the thousand-year Curse User Kenjaku.
Even though the ancient sword Tsukumogami's structure had been destroyed by a direct hit from a Black Flash, repairing it was not difficult for her.
As she said herself, two days would be enough.
The scheduled battle with Yuki Tsukumo was set for a week later during the Goodwill Event between the two schools.
At that time, Satoru Gojo would be staying at Tokyo Jujutsu High, and Mahito would take the opportunity to have a samurai duel with Yuki Tsukumo.
In terms of time, it was more than enough, and Mahito had no complaints about it.
But if there was a better possibility, how could Mahito not pursue it?
Yoto-hime was right before his eyes!
Mahito couldn't help himself; he absolutely couldn't help himself!
To this, the strongest Construction Sorcerer of the past millennium said earnestly:
"Mahito, a sword cannot become a person."
"Wake up."
"Even you can't do it?"
"It's not a question of whether it can be done or not."
Tsumiki Fushiguro spoke in the tone of Miyu Edelfelt telling Illyasviel that 'humans cannot fly'.
"The structural difference between a sword and a human is so vast that it's visible to the naked eye even without understanding it."
"A Construction Sorcerer needs the most basic theory to construct a Cursed Tool."
"Forget theory, calling this a fantasy would be an understatement; this is basically just wishful thinking!"
"Can't you try a little harder?" Mahito looked at Tsumiki Fushiguro expectantly.
"I can't try even a little bit."
"Give up," Tsumiki Fushiguro said expressionlessly.
Mahito was very disappointed.
Tsumiki Fushiguro sighed.
"I can understand what kind of feelings a swordsman has for his favorite sword."
"Swordmaster Ashiya once had to hold the sword I gave him even while bathing and sleeping."
"Until that sword was severed by Lord Sukuna, only then did his obsessive symptoms improve slightly."
"Only slightly; he still never forgot that sword."
"I suspect that up until now, he still hasn't used any other sword because he treats the sword as his lifelong pursuit."
"It's a feeling deeper than that for a lover."
"I suspect he still keeps that broken blade."
"Lord Sukuna's Cleave was perfect, so the cross-section of that broken blade must also be perfect, making it very easy to maintain."
"If a sword really could turn into a person, I have no doubt he would be more fanatical than I am for Lord Sukuna."
Mahito thought of Ashiya's state when he saw Kirigiri a week ago and was very convinced by Tsumiki Fushiguro's judgment.
Old man Ashiya was exactly that kind of person!
"Dagon once said that if there is anyone in this world who can turn an ancient sword into a human, only Miss Yorozu has that possibility," Mahito said.
"He holds you in high regard."
"I've learned many of your deeds from him, among which the Insect Armor impressed me the most."
"I thought if it were you, it might be possible."
"In this modern era, the Insect Armor would be the first Kamen Rider."
Since she could even make the first Kamen Rider, then it should be possible to make a Yoto-hime too, right?
Mahito held such expectations.
Tsumiki Fushiguro frowned.
"Kamen Rider?"
"I remember your Insect Armor mimics the carapace of an insect."
"Isn't that just the first Kamen Rider?"
"My Insect Armor is not a fantasy from a tokusatsu show, but a mature concept," Tsumiki Fushiguro said.
"I used to be very troubled."
"Compared to other techniques, the Construction Technique has an overwhelming shortcoming of low Cursed Energy efficiency."
"Although its total output is no less than that of the powerhouses from the Heian Era, the intense consumption of Cursed Energy makes its frontal combat power insufficient."
"This is the bottleneck for all Construction Sorcerers, one that even the strongest Construction Sorcerer in a thousand years cannot escape."
"In the original timeline, Maki Zen'in's younger sister, Mai Zen'in, was also a Construction Sorcerer."
"The matter generated by the Construction Technique does not disappear after the technique ends, so the consumption of energy is extremely intense, placing a heavy burden on the body."
"The limit within Mai Zen'in's physical safety range was manufacturing one bullet a day."
"This level of consumption essentially rules out any possibility of frontal combat."
"At that time, I heard a rumor that there is a type of bee that can fly across the ocean, and a hornet can fly more than 25 miles in a day."
"Not only that, insects can lift objects hundreds of times their own weight."
"For their size, they can exert immeasurable biting force, jumping power, and speed."
Tsumiki Fushiguro said proudly:
"Therefore, an insect's armor is the pinnacle of the Construction Technique."
"It can exert the maximum output of the Construction Technique."
"As long as I wear the Insect Armor, I can exert power, speed, and protection hundreds of times beyond that of an ordinary person, and I also possess the ability to fly."
"Although it doesn't have the special effects of other Cursed Tools, its output alone is peerless in the world."
Mahito's mouth twitched slightly.
"Isn't this just the first Kamen Rider?"
"The setting of the first Kamen Rider is far too similar to this."
"To say it's exactly the same might be inaccurate, but the general degree of similarity is extremely high."
"In the original timeline, when Yorozu puts on the Insect Armor, she is no different from a Kamen Rider."
"Of course it's different," Tsumiki Fushiguro explained patiently.
"My Insect Armor is actually made on the spot."
"In that era, I couldn't explain it clearly, but in this age, scientific and technological development far exceeds ancient times, so I can use modern terms to explain it."
