While everyone braced for battle, Muzan had yet to realize how serious the situation was. He was still debating whether to flee.
The aura that had suddenly appeared yesterday had given him quite a fright, but he refused to believe anyone could see through his perfect concealment. Besides, wouldn't fleeing now confirm that he had been hiding here?
What if the other party noticed him immediately? That would make things even harder for him in the future!
Even now, he could not forget the terrifying experience a thousand years ago, when that man had nearly killed him with a single slash.
He thought this was merely a coincidence. Besides, it was the perfect opportunity to send those four demons to test that man.
"Nakime, take me to Infinity Castle, and gather the Upper Ranks while you're at it."
Twang~ As the biwa sounded, a vertical Shoji Door opened beneath the feet of the suited Muzan in his room. He calmly dropped through it.
The Shoji Door slowly closed and vanished, as though it had never appeared...
More than twenty kilometers outside Asakusa Castle, a group was on its way.
"Fluctuations from another dimension!" Tobirama pulled the cube, glowing orange, from his clothes and shouted excitedly, ordering everyone to pick up the pace!
With his hands casually tucked into his pockets, Muzan slowly descended into the center of Infinity Castle, where the four Upper Rank demons were already waiting.
A crimson carpet stretched to the end of the corridor. Lanterns burning with ghostly flames hung from towering pillars, illuminating Muzan's cold, handsome profile.
Dressed in a perfectly tailored black suit, his hands in his trouser pockets, he swept an indifferent gaze over the four demons kneeling below him, utterly unaware that disaster was about to strike.
"A probe by humans?"
