It was at this moment that Muzan Kibutsuji realized he was truly going to be defeated. The very idea was abhorrant!
He realized that he could not win this battle, but he could taint the victory of the demon slayers.
Muzan struck his foot into the ground, creating a crater.
"No…" Breathed Tamayo. "It's impossible…"
Muzan gave her a sarcastic smile. "It's too late for you to stop me."
"Maybe. But you will NEVER rise again." For emphasis, Tamayo stamped into the crater as well.
Muzan laughed at her. "Go to hell with me as you wish. But no one will be there to wake you. My demons—"
It was Tamayo's turn to smirk. "Oh did you really think the demons would save you? The second this seal is complete your power over them will break. They will be human, just like Nezuko."
"Pity you will not join them." Muzan spat angrily. "Someone will break the seal in a hundred years. And since you choose to be impertenant I will punish your beloved Demon Slayers!"
Fire burst forth from the crater, burning up all the demon slayers, as Tamayo tried to save them, her blood demon art scorching in the flames.
With that, the Demon Slayers were no more.
