In this world where demons devoured humans.
The human-eating demons hid during the day and emerged at night.
Every night was fraught with danger.
To ordinary people who didn't know the truth, those devoured by demons were merely reported as missing.
However, the Demon Slayer Corps members knew that most missing person cases were caused by demons.
Recently, a series of passenger disappearances on the Infinite Train caught the attention of the Demon Slayer Corps.
Tanjiro, Zenitsu Agatsuma, and Inosuke Hashibira, who joined the corps this year, were assigned to investigate.
Also arriving was Flame Pillar Kyojuro Rengoku, one of the Nine Pillars.
Even with a Pillar accompanying them, this journey on the Infinite Train was still fraught with danger.
The demons' Blood Demon Art was impossible to guard against, especially since their opponent this time was one of the Twelve Demon Moons.
Lower Moon One—Enmu!!!
Under Lower Moon Enmu's Blood Demon Art, over two hundred passengers on the train were deeply entrenched in dreams, unable to extricate themselves.
Even Flame Pillar Kyojuro Rengoku was no exception.
920, just as everyone was about to become the Lower Moon's blood meal.
At the critical moment, Tanjiro was the first to awaken.
At his sister Nezuko's call, he realized that everything he saw before him was an illusion, not reality.
To escape the dream, Tanjiro chose a method few had the courage to do.
He unhesitatingly used the sword in his hand to kill himself, returning to reality.
The moment he returned, he was ready for battle.
After instructing his sister Nezuko to wake the others.
He climbed onto the train car roof alone, confronting Lower Moon One Enmu directly.
"Oh, you woke up so quickly? I rarely let you have such a wonderful dream, why not continue?"
The Sleep Demon Enmu tilted his head, looking at Tanjiro.
"You... don't arbitrarily invade other people's hearts! I will never forgive you!"
Tanjiro roared angrily, his dark Nichirin Blade unsheathed.
Water Breathing—Tenth Form—Constant Flux!!!
A Cham blue great river emerged, surged, and roared as Tanjiro swung his sword.
"Blood Demon Art—Forced Unconscious Hypnosis!"
Enmu faced Tanjiro with the large mouth on the back of his hand.
"Good night!"
Crack!
The absolute sleep power of the Blood Demon Art was released, causing Tanjiro's body to fall sharply.
However, in just an instant, Tanjiro regained consciousness and swung his sword again.
"Why didn't he fall asleep?"
Enmu's face showed shock and confusion, and he continued to try, unwilling to give up.
However, it only caused Tanjiro to stumble slightly.
No matter how he used his Blood Demon Art, he couldn't make the young man in front of him fall.
Only then did Enmu finally understand the reason.
It wasn't that his Blood Demon Art was ineffective, but that the moment he was hypnotized, Tanjiro committed suicide in the dream.
Again and again.
Constantly committing suicide.
Escaping the dream's shackles.
"Don't joke around! How could my family say such things? Don't insult my family!"
Tanjiro let out an enraged roar, and the roaring great river of water swept across Enmu's neck. (cafi) The head... the demon's head fell.
But...
It wasn't over yet.
Flesh-like lumps appeared on the iron train.
That was the result of Lower Moon One Enmu's body completely merging with the train.
"You must be wondering why I didn't die after you cut off my head! Because that wasn't my true body at all, and this isn't either! I've already merged with this train!"
"This train is me! The two hundred passengers on the train are the food in my belly waiting to be digested! Can you protect all of them?"
The Sleep Demon Enmu laughed triumphantly, his entire body sinking into the train car, beginning to execute his subsequent devouring plan.
Woo woo woo~
The night fog enveloped the world, and the roaring train carried over two hundred lives towards death.
On top of the train, the young man's desperate shouts finally received a response from his companions.
"Boar Assault! Boar Assault! Lord Inosuke has arrived!"
The boar-headed boy Inosuke awakened, wielding his twin swords, tearing open the train's roof.
Then came Zenitsu Agatsuma, in a half-asleep state, who swiftly slashed with Thunder Breathing.
Finally, Flame Pillar Kyojuro Rengoku, the moment he awakened, the entire train trembled.
A terrifying storm of flame slashes penetrated five train cars in a row, severing all demon tentacles.
While Kyojuro Rengoku and the others protected the train cars and passengers.
Tanjiro and Inosuke found the neck of Enmu, who had merged with the train.
After a series of arduous battles.
The young demon slayers of the Demon Slayer Corps once again achieved victory against a Twelve Demon Moon.
They successfully protected over two hundred passengers on the train, with no casualties.
However...
The incident was not over yet!
With a loud bang, the train seemed to have hit something hard, and the entire thing was sent flying into the air.
In the endless dust raised by the train's derailment and overturning, a pair of golden eyes lit up.
In the pupils of both eyes, three characters were imprinted.
Upper Moon!!!
Three!!!
