Chapter 115: Decisive Battle

Several days later, at Zero’s mansion.

Xiao Yue was alone in Zero’s room, absorbing the [Energy Crystal] to transform into her adult form, while Zero stood alone in the courtyard, staring blankly at the sky.

For these past few days, the regions under the Ghost Slayers and the Pillar Swordsmen had been unusually quiet.

But Zero knew well: the calmer the time, the fiercer the storm to come.

Of course, that was for this world.

And now, all of this would end tonight, bringing closure to the days of his arrival in this other world.

Kibutsuji Muzan, this little brat, would also bid farewell to this world forever tonight.

As Zero’s thoughts swirled, Xiao Yue stepped out of the room and came into the backyard.

Having absorbed all the energy from the [Energy Crystal], she had fully transformed into her adult form.

Standing one meter sixty-five tall, her long blue hair, deep as the ocean, fell freely to her hips; her delicate features radiated a cold, commanding elegance.

She wore a white shirt, a black cloak draped over her shoulders, a pleated skirt reaching below the knees, black thigh-high stockings accentuating her long, slender legs, and black knee-high boots.

Her gaze exuded maturity and confidence; every movement carried poise and competence.

“Master, Xiao Yue is ready,” she said.

Zero nodded, stroking her head, and smiled: “All these years in this other world—you’ve worked hard.”

Feeling the warmth of Zero’s palm, Xiao Yue’s cheeks flushed involuntarily, and she smiled: “It wasn’t hard. I’m happy to help you, Master.”

“Since you say that, I’ll give you a small reward first. Is there anything you want?”

“Hmm…” Xiao Yue feigned thought, then spoke slowly: “Master… could you… give me a hug?”

At this, Zero gently pulled Xiao Yue into his arms.

Since arriving in this other world, Xiao Yue had grown increasingly human, acquiring emotions and feelings uniquely her own.

Xiao Yue also wrapped her arms around Zero’s waist, leaning against his chest, carefully sensing his aura, listening to his heartbeat—a warmth she couldn’t describe, a familiar feeling she hadn’t experienced in a long time.

…………

In the afternoon, Luo Li arrived at Zero’s mansion with Kanae, Mitsuri, Shinobu, Kanao, Senjuro, members of the Butterfly House, the Ubuyashiki family, and Juuetsu and Yuushiro, both wrapped in thick black cloaks.

Also present were Rengoku Makomo, Sojiro Kuwajima, and Sakonji Urokodaki.

“Everyone, no matter what happens tonight, do not leave this place even a step. I will deal with Kibutsuji Muzan myself.”

Kanae and Mitsuri silently stepped before Zero and each kissed his cheek, speaking in unison: “Be careful. We’ll wait for you to return.”

Zero gave them a reassuring look, then walked to Luo Li, took her small hand, and said gently: “I’m leaving the mansion in your care.”

“Yes. You be careful too.”

Zero kissed her forehead, then left the mansion with Xiao Yue.

Outside the Ghost Slayer headquarters, Himejima Gyomei and the others had been waiting long, their eyes filled with resolve.

Each carried the weapons Zero had given them earlier; after days of practice, they could now use them skillfully.

Zero then turned his gaze to Tanjiro and the three children, along with Munenori and the others, and gave a slight nod.

He took the [Nano Alloy Armored Vehicle] from his [Nanospace] and said: “Next, Xiao Yue will drive this vehicle to take you all to Asakusa in Tokyo.”

Yet even as he spoke, Himejima Gyomei and the others’ eyes burned with eager battle lust.

Though they regretted not facing Kibutsuji Muzan themselves, Ubuyashiki Kagaya had already instructed them: this battle was under Zero’s command.

Moreover, they trusted Zero completely, so they felt no resentment.

Immediately, Xiao Yue took the driver’s seat and activated the vehicle.

Gyomei, Tengen, Munenori, Yuki, Akaza, Shinobu, Muichiro, and Tanjiro entered the rear compartment one by one.

As Xiao Yue drove off in the armored vehicle, Zero contacted Bai Yun through his [Analytical Glasses].

“Xiao Yun, proceed as planned.”

“Understood, brother.”

Boom!

A low engine roar echoed across the sky; Bai Yun calmly activated the [Phoenix]’s invisibility mode and led Units Four, Six, and Nine toward Asakusa in Tokyo to prepare their deployment.

“Just a little demon brat—you’re still as cautious as ever,” Luo Zhan Yun said, appearing silently behind Zero.

Sanhao appeared with him.

Zero waved his hand in reply: “Better safe than sorry. Who knows what other tricks Muzan might have up his sleeve? Also, are the preparations ready?”

“Relax. Everything’s prepared.”

“Good. Then proceed with the plan.”

“No problem!”

Now, all was set—only Kibutsuji Muzan needed to arrive at the Ghost Slayer headquarters.

As for his mansion, there was no need to worry.

With Luo Li there, plus Yuushiro’s Blood Demon Art, they would never be discovered.

…………

Night fell.

From alleyways came a continuous rustling.

In an instant, countless eyeballs engraved with the character [ Si ] surged forth like a fountain—dense, countless eyes, chilling and terrifying.

Inside Infinity Castle, Muzan’s servant, Muzan’s Blood Demon Art released these eyeballs, streaming every captured image directly into his mind.

“Lord Muzan, all is ready.”

“Good. First, teleport all the demons to Asakusa. Then teleport me to the Ghost Slayer headquarters. Let’s see how they handle what’s coming.”

“Yes, Lord Muzan.”

Asakusa, Tokyo.

A strange aura hung in the air, as if countless eyes watched from the darkness.

Ting!

A sudden pipa note rang out; then, one after another, wooden doors materialized out of thin air, and waves of demons poured forth in a relentless tide.

But as the demons stared at the empty streets, they hesitated, confused.

The night-shrouded streets held no lights, no movement—utter silence, no sign of life. The surrounding buildings and villas were the same.

Not even a trace of human presence could be felt—as if the people here had known the demons were coming and fled in advance.

Boom!

Suddenly, a deafening explosion erupted as a bright sphere rose slowly, then burst into blinding light—suddenly, all of Asakusa was bathed in daylight!

The Ghost Slayer forces, long waiting at a hundred meters’ distance, stood silently, staring across at thousands of demons before them.

The great battle was about to begin.
