Both start in hell: but their talents are multiplied a hundredfold.

After Shen Jue sensed a large number of demons appearing near the Butterfly Mansion, he slowly patted Shinobu Kocho beneath him and said, "Shinobu-sama, demons are attacking the Butterfly Mansion."

Shinobu's expression changed; her extraordinary senses of perception and smell failed to detect the appearance of the demon.

"It's still far away from us."

"Please prepare the swordsmen."

Hatred flashed in Shinobu's eyes, and she unconsciously increased her strength. Shen Jue hissed, and then the two quickly packed up and immediately went to inform the swordsmen training at the Butterfly Mansion.

"Come on, come on," Shen Jue muttered to herself. "I've prepared a surprise for you."

In the newly reopened training grounds of the Butterfly Mansion.

Even though it was late at night, Tanjiro Kamado, Zenitsu Agatsuma, and Inosuke Hashibira were still tirelessly training their bodies with weights that were beyond what ordinary people could imagine.

Meanwhile, Mi Douzi waved a small flag to cheer them on.

Tanjiro Kamado, who was diligently training, suddenly changed his expression. Sensing an extremely strong demonic aura, Tanjiro was about to loudly warn his companions when he received a warning that a demon was about to attack.

"Charge! Charge!" Hashibira Inoue shouted as he charged out of the Butterfly Mansion, brandishing his twin swords.

"What?! Why are there demon attacks even in the Butterfly Mansion?!" Zenitsu Agatsuma, the blond-haired guy, screamed in despair. He immediately grabbed his sword and charged at Nezuko's feet, yelling, "Before I die in battle! Marry me, Nezuko!"

Tanjiro Kamado dragged Zenitsu Gasai by the back of his hand and ran out of the Butterfly Mansion. Zenitsu Gasai was still shouting that he wanted Nezuko to marry him.

Inside the Butterfly Mansion, the Demon Slayer Corps swordsmen, under the command of two loli girls from the Ubuyashiki family, set up a defensive perimeter outside the mansion.

Currently, besides the Insect Pillar Shinobu Kocho, only the Flame Pillar Kyojuro Rengoku remains of the Pillars training in the Butterfly Mansion.

The remaining pillars have gone to the area where cannibals are found.

The forest outside the Butterfly House has been newly planted with dense trees, a result of Shen Jue uprooting the dense forest while practicing the Breath of Wind.

These newly planted trees collapsed one after another under the impact of the dense, bizarre cannibals.

The moment the cannibals appeared, they launched their all-out attack.

Several ghosts appeared behind the cannibal army.

The leader of the demons had six extra eyes growing on its forehead and chin.

The two eyes in the middle are engraved with the characters "上弦" (shàngxián, meaning "upper eye") and "壹" (yī, meaning "one").

Six eyes are aesthetically pleasing and allow for clearer capture of combat information, but they also make him look ferocious.

This is the Upper Moon One of the Twelve Demon Moons, the first swordsman of the Demon Slayer Corps, the ancestor of the Mist Hashira Muichiro Tokito, the brother of Yoriichi Tsugikuni, the founder of Sun Breathing, who abandoned his human form for immortality and power, joined the Demon King, and abandoned his wife and children.

Kokugen Shū, a demon who has awakened the markings in his breathing technique and gained insight into the world.

He is also the strongest demon besides the Demon King Muzan Kibutsuji.

He calls himself an "artist," enjoys tormenting others, and hides in a pot as the fifth Upper Moon, Gyokko.

Akaza, the Upper Moon Three, is a fighter who admires the strong and despises the weak.

They depended on each other for survival, but were twisted by extreme "love" and became the ultimate "evil"—Gyutaro and Daki, the sixth Upper Moon.

Five Upper Moon demons, leading a large number of cannibals, launched an attack on the Butterfly Mansion.

"That sir demands that everything that happened in the Butterfly Mansion be recorded and looted."

"That's a really unwise thing to do."

"They actually exposed the coordinates of their logistics and medical base. Has the Demon Slayer Corps fallen to this level?" Kokushikatsu's six eyes darted around as he issued the order to launch an attack.

According to the available information, two Pillar-level fighters and a few ordinary swordsmen from the Demon Slayer Corps remain in the Butterfly Mansion.

"Five against two, the advantage is on our side."

Moreover, the Insect Pillar and Flame Pillar who survived at the Butterfly Mansion were not among the strongest of the many Pillar Swordsmen.

Kokushikatsu was already looking forward to the secret of the Butterfly Mansion.

"Initiate the attack."

Outside the Butterfly Mansion, many swordsmen who had recently undergone the Transformation of Power Breathing Technique and were injected with Super Swordsman Serum had already seen those hideous cannibals.

The cannibals, like the most vulgar wild beasts, launched their attack in packs.

The swordsmen showed no fear, nor did they tremble; their eyes were filled with extreme hatred and the exhilaration of soon avenging their great grudge.

"Die, you demon!" a swordsman roared.

Just as the cannibal army was about to crash into the swordsmen!

A flurry of sword flashes, like shooting stars falling from the sky, ripped through the noisy night, forcefully halting the cannibal army's charge!

The stench of blood was everywhere, and the cannibals' monstrous strength, capable of breaking steel, seemed laughable and childish in the hands of the swordsmen.

Every swordsman in the Demon Slayer Corps has used the Super Swordsman Serum at least a dozen times.

Even the most ordinary members of the Demon Slayer Corps today are warriors capable of tearing man-eating demons apart with their bare hands!

Moreover, the swordsmen are masters of swordsmanship, and their killing ability is incomparable to that of these ordinary ogres and alien ogres!

A swordsman was laughing heartily, a joyful laugh of revenge after crushing the cannibals!

"Charge! Charge!" Hashibira Inosuke launched a fierce attack!

He wielded twin swords, his Armament Haki, generated from his practice of Power Breathing, protecting both swords and his entire body! He fought his way in and out of the cannibal army seven times!

Those mindless cannibals! They couldn't even touch the twin swords enhanced with Armament Haki by Inosuke Hashibira!

Among the three main characters, Inosuke Hashibira's Armament Haki is currently second only to a few Pillar Swordsmen, making him the Demon Slayer Corps member with the highest Armament Haki level outside of the Pillars.

Zenitsu, the blond-haired man, yelled that he was going to die, and then swiftly sliced ​​one of the monstrous creatures in the cannibal army into pieces with a single slash.

Tanjiro Kamado is the most composed of the trio. While slaughtering the army of man-eating demons, he also uses his extremely keen sense of smell to be vigilant against powerful demons that may appear at any time.

"This kind of martial arts?!" Akaza, covered in dark blue tattoos, with short pink hair and golden pupils, and the characters "Upper Moon" and "San" engraved on his eyeballs, was the first to appear at the rear of the cannibal army.

Akaza witnessed the Demon Slayer Corps swordsmen slaughtering the demons and then smiled with excitement.

Akaza, who respects the strong and pursues powerful martial arts, is as excited as the Grim Reaper Shen Jue when he sees dozens of naked, top-tier beauties.

They were about to rush forward and fight!

Kokunobu and the remaining Upper Moon demons followed closely behind and witnessed the swordsmen slaughtering the cannibal army.

Kokushige's six eyes were spinning wildly! What was he seeing?

Those Demon Slayer Corps swordsmen who were originally weak and frail now possess strength comparable to the former Pillar Swordsmen of the Demon Slayer Corps!

Even the weaker former Demon Slayer Corps Pillars swordsmen are no match for these monstrous swordsmen!

"This is a trap!" said Kokushige Tsugikuni. Before the surrounding Upper Moon demons could react, he immediately tried to retreat, only to find that the path he had come from was blocked.

With a smile, Shen Jue led the Insect Pillar Shinobu Kocho and the Flame Pillar Kyojuro Rengoku to seal off the escape route of several Upper Moon demons.

"Then look behind you?" Shen Jue said with a smile.
