Isekai Adventure in the Dimensional Cube

"Boom..."

That was a loud explosion coming from the direction of the town.

It sounded like an explosion, or perhaps thunder. As it erupted, the town immediately burst into commotion — the disturbance was so loud that Reiger and Tamayo, deep in the mountains, heard it clearly.

They had no choice; one had already opened his Transparent World, capable of perceiving his surroundings by focusing on and shutting off unnecessary senses, while the other, a demon with senses far superior to ordinary humans, found the nearby mountain not far from the town. Such a loud disturbance was naturally audible.

"Something's wrong."

The first thought that came to Reiger's mind was just that.

Clearly, Tamayo thought the same.

"It seems as I expected," Tamayo said with a grave face. "Kibutsuji Muzan has made his move."

"What do you mean?" Reiger turned to Tamayo and asked, "Is Kibutsuji Muzan attacking the town? Did you already know about this?"

"No, I didn't know that Kibutsuji Muzan would attack here, but I knew he would eventually act," Tamayo said. "That's the second thing I wanted to tell you."

"Like myself, Kibutsuji Muzan must have had an extreme reaction to the appearance of the name Tsukiguni Yoriichi."

"In his life, he feared nothing more than Tsukiguni Yoriichi. Therefore, given his cowardly nature, once he knew someone claimed to be Tsukiguni Yoriichi, he would definitely take some action, especially since this person also easily decapitated an upper rank three."

In Tamayo's eyes, Kibutsuji Muzan was one of the most cowardly men in the world.

He was deeply afraid of death, so afraid that he sought immortality and a perfect life, even deceiving her into becoming a demon to overcome sunlight, making a grave mistake.

Frightened by his encounter with Tsukiguni Yoriichi, Kibutsuji Muzan stayed hidden from the world until Tsukiguni Yoriichi's natural death, which showed his cowardice.

Kibutsuji Muzan even refrained from gathering his twelve moon demons together, fearing they might unite against him.

Otherwise, why would the upper ranks have not assembled together for one hundred and thirteen years?

It was not for any reason other than Kibutsuji Muzan's cowardice.

Unless absolutely necessary, Kibutsuji Muzan would not let the twelve moon demons gather too closely.

Such a cowardly man, now hundreds of years later, having learned that Tsukiguni Yoriichi had reappeared, would certainly take some action.

Tamayo, having once been very close to Kibutsuji Muzan, understood the demon king's nature well enough.

Thus, Tamayo's visit this time, besides wanting to see Reiger and confirm his relationship with Tsukiguni Yoriichi, was to warn him that Kibutsuji Muzan would surely send someone to track him and find his whereabouts.

"It seems I am still a step late," Tamayo said, furrowing her beautiful eyebrows. "If Kibutsuji Muzan truly followed your tracks all the way here, then we are in big trouble."

After all, this is the Demon Slayer Corps Headquarters, home to the Ghost Hunters and their town.

The Ubuyashiki family is here, as are many important figures of the Demon Slayer Corps, and even the relatives of the corps' members. Once this place is exposed, the demons will undoubtedly attack here.

The recent loud noise and disturbance had already said it all.

"..."

Reiger deeply furrowed his brow, then turned and prepared to leave.

"Please be careful," Tamayo hastily reminded. "Now that this place is exposed, the demons Kibutsuji Muzan sent to attack here are definitely of the upper ranks, and there might even be more than one."

Upon hearing this, Reiger gave Tamayo a faint smile.

"Don't worry about a few upper ranks, even if several Kibutsuji Muzans come, I won't take them seriously," he said.

Saying this, Reiger lowered his body and made a launching motion.

"Boom!"

As Reiger moved, a surge of blazing fire and terrifying high temperatures swept out from him.

"Miss Tamayo!"

Yushirou quickly hugged Tamayo, protecting her as they retreated from the flames and heat.

"This power..."

Tamayo instinctively raised a hand to her face, watching Reiger covered in flames emitting incredible heat, her eyes filled with shock.

"Bang!"

Reiger then forcefully stomped on the ground, creating a shockwave-like gust of wind and dust, shooting into the sky.

Before long, Tamayo and Yushirou could no longer see Reiger's silhouette; they could only see a trail of fire shooting toward the town at an astonishing speed, disappearing into the sky.

"That guy..."

Even Yushirou's often stern face now bore a deep look of shock.

Tamayo kept her eyes fixed in the direction where Reiger had disappeared, her expression growing increasingly brighter.

Having witnessed just the tip of the iceberg of Reiger's power, Tamayo now had every reason to believe.

Believe that this man could do it.

"If it's him, he surely..."

Tamayo anticipated this, hoping with all her might.

Her expression was as if she had seen Kibutsuji Muzan dying miserably right before her eyes.

......

Time, back to ten minutes earlier.

When Reiger had finished forging the sheath in the deep mountains and met with Tamayo, in another deep mountain, The Half Tengu and Tamayoki reappeared.

"This is going to be a beautiful night, shoo shoo shoo,"

Tamayoki no longer hid within the mountain woods; carrying his pot, he arrived at a cliff that overlooked the town, looking in the direction of the town, his lower body merging with the pot, twisting and laughing with elevated emotions.

Half Tengu was still hiding in the bushes, but most of his body was already poking out.

"Your pot has been placed in the town, and no one has noticed anything unusual," Half Tengu said with a fear-like tone, "I've seen many Ghost Hunters there, all in that town. They passed me one after another; if they found me, they would definitely bully me, yi yi, so terrifying, so scary."

"You've worked hard. Among us, your ability to hide your presence is the greatest; you certainly won't be discovered when you go in," Tamayoki ignored Half Tengu's fear, covered his mouth with tiny hands grown on his face, and snickered, saying, "Now we just wait for that foolish woman to arrive, and then we can make a move, shoo shoo shoo."

"She has arrived," Half Tengu curled up into a ball, shivering as he spoke, "But she said she wouldn't come over to us, she'll go directly to the town."

"What?" Tamayoki paused, his voice growing darker, grinding his teeth, "How dare she act on her own?"

"Yi yi," Half Tengu said fearfully, "She said Muzan's orders she will naturally follow, but she doesn't want to see us two freaks; she said seeing us would affect her appetite tonight."

"That damned woman!" Tamayoki yelled, frustration edging his voice, but he soon regained his composure and said, "Forget it, she is not really useful; at most, she's just a brat spoiled by Lord Muzan. If she knew that the Lord Muzan she admires doesn't actually care about her at all, only sparing her a glance because of her brother, I wonder what expression she would have? Shoo shoo shoo!"

"Yi yi." Half Tengu was so frightened that he muttered, "Desperation... that's too desperate... terrifying, terrifying... yi yi yi..."

"Alright, stop crying there, Half Tengu." Tamayoki sneered, "Before that foolish woman messes things up, we should also hurry and begin."

"Yi yi," Half Tengu trembled, "Then then I will go find Tsukiguni Yoriichi's whereabouts."

"Leave the miscellaneous people to me," Tamayoki said, spreading his hands, "I still have some 'creations' I want to make, let the pillars of the Demon Slayer Corps or the Ubuyashiki family taste them, shoo shoo shoo."

Having said that, Tamayoki shrunk into his pot and disappeared from sight.

"Terrifying... terrifying..."

Half Tengu, still curled up, slowly crawled toward the direction of the town.

Tonight, destined to be sleepless.

......

When night fell, the residents of the town also unanimously turned off their lights and went to rest; not many were up talking by candlelight.

This town had a profound connection with Ghost Hunters; everyone knew of the ghosts' existence, and more so that the night belonged to the ghosts, the world dominated by ghosts. Thus, even though this was the town where the Demon Slayer Corps Headquarters was located, the residents subconsciously refrained from being active at night, all returning home once dusk fell, locking their doors and staying inside.

Those who would go out into the streets at this time were likely only members of the Demon Slayer Corps and the Hidden.

Kochou Shinobu emerged from the Ubuyashiki estate, walking towards the Kochou house, feeling oddly uneasy.

"It really is quiet tonight."

Kochou Shinobu gazed at the full moon hanging high in the sky, her eyes flickered, and her emotions fluctuated slightly.

"Am I thinking too much?"

Kochou Shinobu gazed at the moon, pondered for a while, and suddenly tapped her own head, sticking out her tongue.

"Seems I'm too sensitive, blame Tsukiguni for making me think too much today."

"Well, it's not like I don't usually think much anyway."

"You think so? Sister..."

Leaving such words behind, Kochou Shinobu self-mockingly smiled, no longer pretending to be cute, her face also shedding its usually contrived smile, like a butterfly shedding its dazzling wings, walking towards the Kochou house.

Walking along, Kochou Shinobu stopped.

"...It seems it wasn't just me being oversensitive."

After murmuring softly, Kochou Shinobu lifted her eyelids, looking ahead.

There, a figure had appeared without a sound and unnoticed.

"Looks like I'm in luck, just entered the town and I've met a desirable target,"

The figure spoke with a presence so palpable, so powerful, and so self-assured, addressing Kochou Shinobu under the moonlit sky.

"Such a pretty little girl, hey, wouldn't you like to be my meal?"

The figure grinned maliciously.

Kochou Shinobu did not speak, but a smile emerged on her face.

That smile, it was very fake.
