The course of heaven was constant; it did not endure for Yao, nor perish for Jie.
In this world, no matter who was missing, the sun would rise as usual.
Yet a butterfly in the tropical rainforest basin of the Amazon River in South America could, with an occasional flap of its wings, cause a tornado in Texas, United States, two weeks later.
Because of the influence of Mu Yu, this little butterfly, the conflict between humans and demons in the Demon Slayer World began to intensify dramatically.
Whether they were the Twelve Kizuki or ordinary demons, they began devouring people on a massive scale, and cries of grief filled the land.
Likewise, the Demon Slayer Corps launched an unprecedented demon-hunting operation, and casualties steadily mounted!
Ishibashi Town.
It was an ordinary, backward little town. Even the fresh winds of modernization had yet to reach it.
But starting a week ago, all the peace of this once picturesque town vanished.
For everyone had inexplicably contracted a terrible disease. Every night, every night, every night, living people died from it.
And tonight, the town became even more unsettled.
Because the Demon Slayers had arrived!
The greater everyone's expectations of the Demon Slayer Corps had initially been, the greater their disappointment was now.
Against the demon that had created the epidemic, the Demon Slayer Corps was utterly powerless.
Worse still, because the Demon Slayers had arrived, the demon used them as tools to fend off the Corps.
The illnesses in their bodies all began worsening. It was as though they were living in hell.
"It hurts so much... I feel so awful... I want to die..."
The torment of disease was unprecedented. In just a few days, Ishibashi Town's residents had been tortured until they were gaunt and haggard, like walking corpses.
