A Blood Demon Art.
And a wide-ranging Blood Demon Art that covered the entire train.
Sasuke reached that conclusion in an instant.
The cloyingly sweet pink mist, with its hypnotic effect, was seeping from every corner, permeating everything.
Yet strangely, the others in the carriage, including the Hashira Kyojuro Rengoku, seemed completely unaware.
"Delicious!"
Kyojuro finished another Beef Hot Pot Bento and let out a satisfied exclamation.
He ate extremely quickly, but his movements were not crude. Instead, they brimmed with vitality.
Tanjiro watched from beside him, an admiring smile on his face.
Inosuke stuck his head out the window, feeling the wind rush past as he shouted excitedly.
Zenitsu huddled in a corner, muttering about whether even more terrifying demons lay ahead.
Everything looked so normal.
That stark contrast made Sasuke realize how tricky the situation was.
This Blood Demon Art did not attack directly. Like boiling a frog in slowly heated water, it eroded people's minds without their noticing.
Shouting "There's a demon!" now would only cause unnecessary panic.
Besides, he could not explain how he could "see" this mist.
Sasuke decided to watch and wait.
He gathered a trace of chakra in his nasal passages, filtering out the cloying scent while keeping his mind absolutely clear.
His Three-Tomoe Sharingan analyzed the flow of the mist and everyone's reactions like the most precise instruments.
Just then, the carriage door slid open.
A man in a conductor's uniform walked in.
"Excuse me. I'll be checking your tickets now."
His voice was flat, and he wore a routine smile, but his eyes were empty.
Sasuke's gaze immediately locked onto him.
Through the Sharingan, he could see faint pink mist coiling around the conductor. Deep in his pupils, there was not a trace of the light of a living person.
