Demon Slayer: The Journey That Began When I Became Yoriichi's Sister

Upon hearing Xuanmi mention Orange Light Ikuko, he knew what was going on and sighed, "It's Infinite Castle."

Infinite City?

Everyone was stunned for a moment.

Mitsuri Kanroji, who was snuggling in Shinobu's arms, turned her head and said, "Infinity Castle? I feel like I've seen it somewhere before?"

Shinobu Kocho smiled helplessly: "It's from the information Ikuko gave to the lord, isn't it?"

Kanroji Mitsuri slammed her right fist into her left palm, suddenly realizing, "Ah! Now that you mention it, I remember!"

"What are the pipa player's abilities?"

Ikuko wrote down everything she knew about the Upper Moon demons and Muzan Kibutsuji.

Even though she could hardly remember what she had written later, she could still understand the Upper Moon demon's abilities whenever she saw it.

There isn't much information about the Biwa Girl. Yuko doesn't even know if she's an Upper Moon demon. The only information she has is that she possesses an alternate dimension, where Muzan's headquarters are located.

Based on the current information, Kokushibo, Doma, Akaza, the Upper Moon Four who just fought Tanjiro and the others, and the siblings Gyokko and Gyutaro are involved.

This pipa player should not belong to the category of "upper string".

……

It shouldn't be possible that there's an Upper Moon Zero above Kokushibo, right?

She regretted more than once why she hadn't been able to keep up with him in her past life.

Yuko sighed softly. Although she felt that he shouldn't be more powerful than Kokushibo, the incomprehensible grand scene was really hard to explain.

It's like a city walled city; it's truly magnificent.

She even felt that his ability was far superior to that of Muzan, the Demon King.

After all, when you compare a combat power that has nothing to offer except for its numerical value with that magnificent scene, it's obvious which is stronger or weaker, right?

Blood Demon Arts is truly a wondrous thing.

Tanjiro asked curiously, "Can that ability make a demon disappear instantly?"

Shinobu Kocho shook her head: "It's not disappearing, it's falling."

"come down?"

"A door will open on the ground, and then you'll fall into the Infinity Castle through that door." Shinobu Kocho put a finger to her lips, thought for a moment, and said, "That's roughly it, right?"

As she spoke, she turned to look at Yuko.

Yuko nodded slightly: "I will discuss the Infinite Castle matter with Ubuyashiki in detail later."

That ability...

You really need to be careful.

Fortunately, Muzan did not discover the Demon Slayer Corps' base, otherwise, the biwa-playing woman's abilities alone would have caused the Demon Slayer Corps great turmoil.

It's even possible that they could eliminate Ubuyashiki without anyone noticing.

That sudden feeling of weightlessness would be impossible for anyone but a seasoned swordsman to react to.

If she were Muzan, she could use this ability to gradually dismantle the Demon Slayer Corps.

"Speaking of which, what brings Shinobu here?" Kanroji Mitsuri asked curiously. "I'm here because the area I'm patrolling is very close to the sword-forging village."

"Didn't Shinobu go back to the Butterfly Mansion?"

Butterfly paused for a moment, a blush rising to her face: "Ah, I heard about the attack on the sword-forging village, so I came ahead of time."

She wasn't lying, after all, the hidden logistics and rescue force was indeed behind them.

Although Kanroji Mitsuri is usually a bit silly, she's not stupid.

One step ahead...

That distance... even if she ran at full speed all night, it would be difficult, right?

Yuko, having helped Shinobu out of the awkward situation, changed the subject and asked Tanjiro, "Where's Tokito?"

"Tokito stayed in the village to organize the rescue work."

“Organize rescue work? Can Tokito do it?” Yuko was stunned for a moment. In her understanding, Tokito was a clueless boy who couldn’t say a few nice words.

Even if you let Kanroji... no, come to think of it, it seems like Tanjiro is the only one who's easy to deal with.

Tanjiro broke out in a cold sweat but didn't reply.

"Let's go back first. Kokushibo has been taken away by the Infinity Castle." Yuko's eyes twitched slightly as she looked at Inosuke, who was still looking around and jumping around.

"Ah, everyone, let's go back to the village first."

On the way, Yu Zi pondered the events of the evening.

Muzan already knows about her overcoming sunlight, so she'll probably crawl out of that ditch eventually.

Muzan has been thinking about this opportunity for thousands of years, and has been searching for the blue spider lily for thousands of years. He's probably almost gone crazy with longing for it.

Now that a demon capable of overcoming sunlight has finally appeared, if we eat her, we might be able to overcome sunlight.

Muzan will never let go.

Muzan is very composed and cowardly, but he also has a lot of pride inside.

Someone like Yoriichi isn't someone you see every day.

The others are not to be feared.

Yuko was certain that the guy would make a move, a move unlike anything she had ever made before.

She originally planned to wait until Tanjiro and the others became stronger, and until Nezuko overcame the sunlight, before intentionally letting Muzan know the news, so that they could take the initiative and launch the final battle.

Unexpectedly, she was the one who suffered a loss.

Instead of killing her, Kokushibo revealed her secret of overcoming sunlight.

Yuko's mood became somewhat heavy.

“Yuko…” Shinobu Kocho seemed to have been watching her closely and quickly noticed her unusual behavior. She gently placed her hand on her back to comfort her.

Yu Zi smiled and said, "I'm fine."

Shinobu Kocho pursed her lips: "Let's go back and change our clothes first."

She didn't even realize that she had stuck to Yu Zi's back and gotten it all over herself.

Although it can regenerate, the demon is not without consciousness, and Yuko must have gone through a fierce battle.

Shinobu Kocho felt a pang of regret. If only she could have come earlier... or even stayed in the Swordsmith Village.

The group returned to the sword-forging village, which was attacked by three Upper Moon demons during the night. However, only the battle between Hantengu and Tanjiro's group actually affected the village.

Yu Hu was killed by Yu Zi before he could even catch his breath. The battle with Kokushibo took place deep in the mountains and forests. Although the vegetation was severely damaged and it may cause soil erosion and mudslides in the future, at least there were no casualties.

Ok……

It's a shame about that doll; it was quite interesting.

The damage caused by the Half-Heaven Dog was considerable, but because the retreat was timely and Yuko killed Yuko early on, the clones Yuko left behind were rendered useless and the village did not suffer many casualties.

Everyone gathered together to clean up the ruins destroyed by the Half-Heaven Dog.

Yuko simply wiped herself down and changed into some casual clothes.

"Whoo~"

Yuko pushed open the door and let out a long sigh of relief. Sure enough, these clothes were the most comfortable to wear.

"All done?" Shinobu sat on the porch, turning to look at Yuuko, her purple eyes filled with a hint of disappointment.

Such simple clothes...

"Hmm, can't you bear to help?"

Shinobu Kocho smiled mischievously: "The hidden guards have already arrived. The villagers aren't seriously injured, so we don't need me~"
