As soon as Mizuki heard Genya mention the orange light, she knew what was going on and sighed, "It's the Infinity Castle."
Infinity Castle?
Everyone was stunned for a moment.
Kanroji Mitsuri, who was cuddling in Kochou Shinobu's arms, turned her head and asked, "Infinity Castle? I think I've seen that somewhere?"
Kochou Shinobu gave a helpless smile. "It must have been in the intelligence Mizuki provided to Oyakata-sama."
Kanroji Mitsuri hit her right fist into her left palm, suddenly realizing, "Ah! Little Shinobu, now that you mention it, I remember!"
"The ability of that Nakime?"
Mizuki had written down all the information she knew regarding the Upper Rank Demons and Kibutsuji Muzan.
Even though she barely remembered the content she had written down later, she could still understand the Upper Rank Demon's abilities just by seeing the notes.
There wasn't much information about Nakime. Mizuki didn't even know if she was an Upper Rank Demon; the description of her ability merely stated that she possessed a unique dimension, and Muzan's main base was located there.
Judging from the current intelligence, there are Kokushibou, Douma, Akaza, Upper Rank Four who just fought Tanjirou and the others, as well as Gyokko and the siblings Gyuutarou.
This Nakime shouldn't fall within the Upper Rank category... probably... There couldn't possibly be an Upper Rank Zero above Kokushibou, right?
She regretted more than once why she hadn't finished watching the series in her previous life.
Mizuki sighed softly. Although she didn't think it would be more powerful than Kokushibou, that incomprehensibly grand scene was truly hard to describe clearly.
It was practically like a massive fortress; it was too magnificent.
She even felt that ability was overwhelmingly superior compared to Muzan, the Demon King.
After all, when comparing the combat power that was useless except for its numerical value, against that magnificent scene, who was stronger and who was weaker was immediately obvious, right?
Blood Demon Art truly is a wondrous thing.
Tanjirou asked curiously, "Can that ability make a demon disappear instantly?"
Kochou Shinobu shook her head. "It's not disappearing; it's falling."
"Falling?"
"A door opens on the ground, and then they fall through that doorway into the Infinity Castle." Kochou Shinobu put an index finger to her lips, thinking. "That's roughly how it works, right?"
As she spoke, she turned her head to look at Mizuki.
Mizuki nodded slightly. "I will discuss the matters concerning the Infinity Castle in detail with Ubuyashiki later."
That ability... must be watched carefully.
Fortunately, the Demon Slayer Corps headquarters hasn't been discovered by Muzan, otherwise, just using Nakime's ability could throw the Demon Slayer Corps into utter chaos.
It might even be possible to eliminate Ubuyashiki without anyone noticing.
That sudden feeling of weightlessness—if it weren't for battle-hardened swordsmen, they absolutely wouldn't be able to react in time.
If she were Muzan, she could use this ability to slowly dismantle the Demon Slayer Corps.
"Speaking of which, why are you here too, Little Shinobu?" Kanroji Mitsuri asked curiously. "I'm here because the area I was patrolling was very close to the Swordsmith Village."
"Didn't Little Shinobu return to the Butterfly Mansion?"
Kochou Shinobu paused, a blush appearing on her face. "Ah, I heard about the attack on the Swordsmith Village and rushed here ahead of the others."
Her words weren't exactly a lie. After all, the Kakushi Corps tasked with logistics and rescue were indeed following behind.
Although Kanroji Mitsuri was usually silly, she wasn't an idiot.
Ahead of the others... that distance... even if she ran at full speed all night, it would be tough, wouldn't it?
Mizuki rescued Kochou Shinobu from the awkward spot, changing the topic by asking Tanjirou, "Where is Tokito?"
"Tokito-kun stayed in the village to organize the rescue efforts."
"Organize rescue efforts? Can Tokito handle that?" Mizuki was stunned for a moment. The Tokito she knew was a detached, emotionless youth who rarely said anything nice.
Even if you asked Kanroji... No, come to think of it, only Tanjirou seems relatively worry-free.
Tanjirou sweatdropped and didn't reply.
"Let's head back first. That Kokushibou guy was also taken away by the Infinity Castle." Mizuki's eyelid twitched slightly as she watched Inosuke still looking around and bouncing up and down nearby.
"Ah, everyone, let's return to the village first."
On the way, Mizuki pondered the events of the evening.
Muzan now knew that she had conquered the sun, and he would surely crawl out of that gutter.
Muzan had dreamed of this opportunity for a thousand years, searching for the blue spider lily for a thousand years; he was probably going mad thinking about it.
Now that a demon who conquered the sun had finally appeared, by eating her, he would likely be able to conquer the sun himself.
Muzan would absolutely not let go of this chance.
Muzan was very cautious and cowardly, but deep down, he also had pride.
An existence like Yoriichi doesn't appear just anytime.
Everyone else was not worth fearing.
Mizuki was certain that guy would make a move—an unprecedented move.
She had originally planned to wait until Tanjirou and the others grew stronger, and Nezuko also conquered the sun, before deliberately letting Muzan know the news, allowing them to seize the initiative for the final battle.
She hadn't expected to be the one suffering a setback.
Not only did she fail to kill Kokushibou, but she also exposed her secret of conquering the sun.
Mizuki's mood couldn't help but grow heavy.
"Mizuki..." Kochou Shinobu seemed to have been watching her, quickly noticing her unusual state, and gently placed a hand on her back to comfort her.
Mizuki smiled. "I'm fine."
Kochou Shinobu pursed her lips. "Let's go back and change your clothes first."
She hadn't even noticed that by leaning against Mizuki's back just now, she had gotten covered in stains herself.
Although demons can regenerate, they are not without sensation. Mizuki must have gone through a fierce battle.
Kochou Shinobu felt a knot in her heart. If only she had arrived sooner... or simply stayed in the Swordsmith Village.
Everyone returned to the Swordsmith Village. The village had been attacked by three Upper Rank Demons during the night, but in reality, only the battle between Hantengu and Tanjirou and the others had affected the village itself.
Gyokko was slain by Mizuki before he could even catch his breath, and the fight with Kokushibou took place deep in the mountains. Although the vegetation was severely damaged, which might cause soil erosion and landslides in the future, there were at least no casualties.
Hmm... it's just a shame about that puppet; it was quite interesting.
The damage caused by Hantengu was considerable, but because the retreat was timely, and Mizuki had slain Gyokko early on, the Clones Gyokko left as a contingency didn't get a chance to act and vanished. Thus, there weren't many casualties in the village.
Everyone gathered together to clean up the ruins damaged by Hantengu.
Mizuki simply wiped her body down and changed into a set of casual clothes.
"Hoo~"
Mizuki pushed open the door and let out a long breath. Sure enough, these kinds of clothes were the most comfortable to wear.
"All done?" Kochou Shinobu sat on the porch, turning back to look at Mizuki, her purple eyes showing a hint of disappointment.
Such plain clothes... "Yes. Aren't you going to help, Shinobu?"
Kochou Shinobu smiled playfully. "The Kakushi Corps have arrived, and the villagers' injuries aren't severe, so they don't need me~"
