On this moonlit night.
Muzan Kibutsuji, the "evil of this world," and his long-time pursuer are facing each other head-on.
Muzan Kibutsuji did not want to miss the good opportunity to kill Ubuyashiki Kōya, but he had doubts in his heart. That is, what kind of trap would Ubuyashiki Kōya, who had already known about his arrival, set here.
"It feels strange. There are only four people in this house: Ubuyashiki, his wife, and two children. There are no guards, and no one else..."
What on earth made Ubuyashiki Kazuya show such fearlessness in front of him?
"Let me guess, Muzan... I understand that you dream of eternity and desire immortality."
Muzan Kibutsuji lowered his brows, and his pair of vertical pupils appeared even colder. The scarlet color lit up in the moonlight, like two will-o'-the-wisp fires, hiding an unfathomable cruelty.
"Yes, and it will be realized soon, as long as I get Nezuko..."
Muzan Kibutsuji knew that it would be difficult to catch Suwey and he had to plan for the long term, but Nezuko Kamado was different. It was her figure standing in the sun that made Muzan Kibutsuji completely believe in Suwey's BUFF.
So he plans to capture Nezuko Kamado, eat her, and try to take her place to see if he can fight the sun.
This was also one of the reasons why he raided the Ubuyashiki mansion.
"Your dream will never come true, Muzan."
Ubuyashiki Yoya interrupted Muzan Kibutsuji's words without hesitation. He tore apart his plan without showing any respect to the Demon King in front of him.
"You are very confident about where to hide Nezuko, but I am different from you. I have plenty of time..."
For thousands of years, the Demon King, who had been high and mighty, was actually taught a lesson and even stimulated by a young man who was only in his twenties. This made Muzan Kibutsuji very embarrassed, so his expression gradually became ferocious and his look became worse.
"Shut up!"
Muzan Kibutsuji lowered his eyebrows. The anger and murderous intent of the Demon King stirred up the situation nearby, making the atmosphere in the entire Ubuyashiki mansion suddenly become dangerous.
The girls who were humming nursery rhymes and playing the flute stopped at the same time. Their eyes passed over Muzan Kibutsuji and stopped on Ubuyashiki Kōya.
"Well, that's enough. I've said everything I've wanted to say to you. I didn't expect you to listen to me finish. Thank you, Muzan, and then... never see you again."
As Ubuyashiki Kazuya smiled and spoke in a voice that sounded like a final declaration, a little light was reflected in Muzan Kibutsuji's pupils as if in slow motion, and then the light spot gradually got closer, bringing a huge impact that hit him hard.
boom!!!
The whole world seemed to be turned upside down in an instant. Everything around disappeared, starting with the slightest sound of the wind, and then there was an intense burning heat and flames shooting up into the sky.
The explosion of concentrated power took only a moment, and the entire sturdy Ubuyashiki mansion and the mountaintop were shattered into pieces as if they were torn apart by a violent tornado, and everything was reduced to debris.
When the explosion occurred, everyone at the foot of the mountain felt it. The vibration from the soles of their feet and the gunpowder buried under the Ubuyashiki mansion produced a shock even more exaggerated than an earthquake.
Then, flames shot up into the sky, and black smoke rose from the burning mountaintop, like a beacon that sounded the clarion call of war, causing every prepared member of the Demon Slayer Corps to rush up the mountain without hesitation.
"A huge amount of explosives!!! The smell of blood and burning flesh!"
Tanjiro Kamado, who was being beaten, suddenly covered his nose. The smell coming down with the wind was filled with something that made him feel nauseous. He also realized that a crisis was about to break out.
