Regarding Nakime, the Demon Slayer Corps naturally had records.
They didn't know her name, but after Kaito roughly described her appearance and abilities,
sure enough, after having people search through past intelligence archives, information on this Demon was found.
However, when they found this intelligence, it was from three years ago. She had been sighted in a large town in Osaka. A Kinoe member stationed there at the time had spotted her.
After discovering her, she simply lightly played her biwa, a sliding door appeared behind her, and she disappeared after walking through it.
This Demon Slayer Corps' member had recorded her general appearance and such a peculiar Blood Demon Art, sending the intelligence here.
"I'm sorry, this is all the information we have. I hope it can help you."
"That's enough. A general location is fine. Maybe she still lives in that town?"
Or maybe...
Muzan was also hiding there?
And later, he went to Asakusa, and was discovered by Tanjiro.
Well, a general location was enough. He could search slowly from there. It was better than searching the whole of Japan.
As long as Nakime didn't enter the Infinity Castle, he could find her.
"Alright, you should rest. I leave Tanjiro in your hands."
Seeing Ubuyashiki's breathing gradually weaken, Kaito didn't linger.
After taking his leave, Kaito chatted briefly with Rengoku, urging him to quickly learn Sun Breathing from Tanjiro. He also mentioned things like awakening the Mark, achieving the Transparent World, and using the Crimson Blade before saying goodbye.
Incidentally, he silently placed ten layers of shields on Rengoku and gave him a rock jade pendant to pass on to Ubuyashiki.
This was all he could do.
He had no intention of helping Ubuyashiki; that was his fate. He wasn't Tanjiro, someone Kaito cared enough about to help.
After he left this world, he truly wouldn't care what happened. So this was all he could do.
Rengoku and Tanjiro were different; they were characters he liked.
Leaving Ubuyashiki's residence, Shinobu led Kaito and Mitsuri to the Butterfly Mansion to rest temporarily. After dinner, they would go to her sister's grave.
Naturally, Shinobu was very anxious inside, but since she was sure her sister could be revived, being anxious now was useless. It was better to properly entertain Kaito first...
Well, actually, Shinobu hadn't fully mentally prepared herself yet.
First, her sister was about to be revived.
Second, she was to become Kaito's attendant...
Whether she could continue to stay in the Demon Slayer Corps was unknown. Returning to the Butterfly Mansion now, she was also rushing to handle some tasks and write down all her medical experience for other doctors.
"Husband, what are you looking at?"
After the meal, in the garden of the Butterfly Mansion.
Kaito was resting here, waiting for Shinobu to finish her tasks.
Although it wasn't necessary for her to do so, as he wouldn't be taking her away from this world so soon...
Well, mainly he couldn't take her away yet.
Besides the chat group system not having this function unlocked yet, the small world hadn't reached the condition to allow people to be brought in.
So, he needed to wait a little longer.
Currently, the chat group only allowed traversal for close family relations.
For example, one's own children. Others were not permitted, even a wife was not allowed.
Kaito didn't know how to comment on this, but the fact that chat group items could be used by close friends and family was perhaps the maximum permission the chat group could grant.
More than that wasn't possible; he could only rely on his own abilities to help.
Well, for now, Shinobu could either stay in the Demon Slayer Corps or stay with Kie. Kaito was fine with either.
Eventually, he would definitely take Shinobu and Mitsuri with him.
Of course...
Kanae wouldn't escape either.
And also...
The girl in front of him, quietly blowing bubbles, Tsuyuri Kanao.
She was now exactly fourteen years old, but still retained a youthful face, like a pseudo-loli.
Perhaps it was because she was the petite type?
No matter how he looked at her, approaching her felt like a "three-year minimum, death sentence maximum" situation.
Well, that statement wasn't really relevant.
"I'm watching that girl blowing bubbles."
Kaito answered directly. Mitsuri followed his gaze to Mitsuri and smiled slightly.
"Has my husband taken a liking to her?"
"???"
'Wait, why are you even more direct than me?'
'I just mention it, and you immediately assume I like her?'
"Cough, why do you say that? What if I just wanted to know who she is?"
"Hehehe... Isn't it natural for my husband to like pretty girls? Or do you only want a few wives? From what I know, those feudal lords, rich people, and such have many, many wives!"
'Gasp...'
'Really!?'
'Was I living worse than those people!?'
But since Mitsuri said so, it meant she had either heard about it or seen it firsthand.
Indeed!
In this era, men with power and status definitely wouldn't be short of women.
Thinking about those men, it was even more certain.
Women's status in this era was too low. Some people truly treated women only as tools for bearing children, or as mere garments.
"I'm not like those people."
After a moment's thought, Kaito felt he needed to set the record straight.
Even if what Mitsuri said wasn't wrong...
But he still had his pride, didn't he?
"I see. But if my husband likes her, I don't mind. I only hope you won't abandon me."
'Oh...'
'This damn traditional mindset!'
'It was too beautiful... beautiful...'
"Cough, we'll talk about that later. Later."
"Hehe, okay!"
Mitsuri didn't say anything more. She smiled happily for a while, then nestled into Kaito's arms, looking at the sky, idly waiting for Shinobu's arrival.
"Sigh... I've finished some things, Mr. Kaito."
After a while, Shinobu appeared, holding some kimonos, presumably for her sister to wear.
Because she didn't know if her revived sister would be clothed or not.
See, how thoughtful she was!
