Not responding to Mitsuba's teasing, looking at Koyuki who had fainted again with a silly smile, Akaza merely stood up calmly.
He walked straight to Mitsuba, then suddenly raised his hand and embraced her tightly.
"Oh my? What's this?"
"Big sis, thank you."
In Mitsuba's puzzled gaze, Akaza held her tightly, speaking word by word in her ear:
"Thank you for not letting me sink into degeneration, thank you for always stopping me from wantonly creating killing karma, thank you for teaching me to read and write, teaching me the principles of being human.
Thank you for never giving up on me in the past three hundred-plus years, persistently guiding me away from that path of degeneration. Truly, thank you..."
For Akaza, the greatest fortune was that when his memories returned and he fully understood everything, looking back he discovered—
In his long past of three hundred-plus years, those he had killed were only Demon Slayers who could be called enemies.
In three hundred-plus years, he had actually never harmed a single ordinary human.
Not only that, he had actually learned to read and write, learned to treat people with kindness, shed that violent temperament, transformed completely, and become a teacher respected by others who educated and nurtured people.
Even, he had actually encountered his former fiancée again, encountered his former master, and at the most appropriate moment, recovered his memories...
Listening to the sobbing cries by her ear, Mitsuba merely smiled gently, raising her hand to lightly pat his back.
"Hakuji, there's nothing to thank for this. Didn't I say back then? Since I made the choice for you, I would definitely take responsibility for you to the end.
Alright, it's about time. I still have some matters to handle next. Hurry and take your fiancée home."
Mitsuba hadn't forgotten that Ubume and Enmu were still dealing with Rengoku at this moment.
In the current Infinity Mountain Villa, only those two Lower Rank demons remained alive.
The other three had already been slain by Demon Slayers. Without unexpected developments, these Demon Slayers should be gathering toward Rengoku's direction right now.
If she didn't go over, Ubume and Enmu probably wouldn't be able to hold out.
"I'll go with you."
At this moment, Akaza suddenly released Mitsuba. He wiped his eyes and spoke thus.
Mitsuba was somewhat surprised upon hearing this.
"You're not going back with this young lady?"
"I want to, but I can't just leave everything for big sis to handle, right?"
Speaking thus, Akaza removed his suit jacket and draped it over Koyuki, simultaneously contacting Nakime through mental communication.
[Sister-in-law, help me send Koyuki home. I've already sent you the coordinates...]
In the next instant, Infinity Castle's gate suddenly opened beneath Koyuki, receiving the unconscious her inside.
But this wasn't the end.
The instant Koyuki fell into Infinity Castle, beneath her another gate suddenly opened, receiving her inside once more.
However, this gate was an exit gate from Infinity Castle, its position directly facing the bed in the second-floor bedroom of Koyuki's home in Tokyo.
Through Infinity Castle as this "transfer station," Nakime instantly transferred Koyuki from the cinema hall of Infinity Mountain Villa to her home in Tokyo hundreds of kilometers away.
"Alright, let's go."
Completely without worries, Akaza walked straight toward outside the cinema hall.
"Little Hakuji, sending that girl back just like this, you probably won't have an easy time explaining later, right?"
Walking beside him, Mitsuba reminded him.
After all, falling asleep and instantly returning to Tokyo—ordinary people would certainly become suspicious.
"It's fine. When the time comes I'll tell Koyuki that it was that bastard Doma who suddenly came to pick us up by airplane, and she slept like the dead along the way so didn't notice..."
Oh~ so that's how it is~ there's actually this kind of explanation method?
Hearing this, after brief thought, Mitsuba felt greatly shocked.
Indeed!
No matter how absurd something was, as long as it was placed on Doma, everyone would naturally feel that this was definitely something Doma could do!
She never expected Doma could be used this way. How had she never thought of this before?
It seemed her development of Doma's uses was still too low...
"Speaking of which, big sis, is that big butterfly beside you alright?"
"Ah, it's fine. I already communicated with that child before. After she wakes up, she will do what she should do."
The two chatted casually like this, quickly walking toward the wide street behind the cinema hall where fierce battle was occurring.
On the way, they even happened to encounter an old woman fleeing in panic.
"Terrible! Murder! Someone's killing people on the northern street!
There's a man wearing a red haori, wielding a samurai sword, chasing and cutting down a staff member in the street! Young man, young lady, you two hurry and flee!"
Warmly supporting this frightened old woman, Akaza smiled and said:
"We know, Grandma. We're precisely going to handle this matter. You hurry home."
"Ah? T-then you two must be extremely careful! That murderer's blade can spew fire! I saw it with my own eyes! Very terrifying!"
"Yes yes yes, we understand. Grandma, take care, watch your step."
After bidding farewell to this old woman who had accidentally witnessed the scene of Rengoku chasing Enmu, Akaza and Mitsuba hadn't walked far north before they saw the battlefield where both sides were fighting.
Ubume, Enmu, Rengoku, Tanjiro's group, and some Demon Slayer swordsmen serving as atmosphere...
"It looks like, everyone's about gathered... Big sis, hold this for me."
Walking toward the confrontation ahead, Akaza raised his hand and lightly removed his glasses, tossing them to Mitsuba behind him.
With this action, his gray-black pupils instantly returned to golden yellow. The characters "Upper Rank" and "Three" emerged within them.
"Little Hakuji, be careful yourself, alright?"
Behind him, Mitsuba accurately caught the glasses he tossed, reminding him with a smile.
Her gaze glanced at Ubume who was about to engage Rengoku and Tanjiro once more. She suddenly raised her hand and lightly snapped her fingers.
In the next instant, from within Ubume's body, that mandala flower she had kept for nearly twenty years rapidly flew out, expanding a blood-red mandala domain that blotted out the sky and moon!
Mitsuba sought stability. As long as it was within her domain, no matter what happened she could handle it.
"Rest assured, just a few Demon Slayers, easy and relaxed."
Akaza waved his hand. His black short hair faded to pink, muscles bulging, that originally seemingly thin physique instantly becoming incomparably robust.
"Tch, had I known there would be fighting tonight, I should have changed into looser clothes..."
Raising his hand to loosen the tie at his chest, simultaneously unbuttoning several buttons on his shirt, Akaza thus stepped one foot into Mitsuba's domain, an excited smile on his face.
Perfect, it had been over three hundred years since he properly fought anyone. Tonight, let him enjoy himself thoroughly!
