Muzan looked grim.
He had, in fact, already learned a few things.
What had happened this time made him nervous.
Yes, nervous.
"My lord!"
"I still don't really understand what happened this time."
"Even though Hantengu told me a great deal, I couldn't make sense of what he said."
Gyokko sounded helpless.
He and Hantengu had returned together.
But...
On the way back, Hantengu had kept babbling nonsense.
Granted, he sometimes struggled to understand what Hantengu said even under normal circumstances.
Now... he seemed so utterly terrified that he couldn't explain anything clearly.
For a moment, every Upper Rank present turned to look at Hantengu.
"Someone terrifyingly powerful has appeared in the Demon Slayer Corps."
"He... he killed my... my clones in an instant."
"I never even sensed him make a move before my clones died."
"And he has a special ability that lets him instantly heal the Demon Slayers' injuries."
"A brat..."
Seeing that Muzan Kibutsuji was watching him too, Hantengu trembled as he recounted everything that had happened to him.
Akaza, who had initially been rather dismissive, suddenly grew excited.
Kokushibo, however, was unimpressed.
In his eyes, this had only happened because Hantengu was far too weak.
It wasn't much of a problem at all.
As far as Kokushibo was concerned, all fear, helplessness, and hardship stemmed from a lack of strength.
Doma still looked utterly unconcerned.
A powerful enemy?!
It wasn't as though they had never encountered one before.
All that had happened was that another powerful opponent had appeared.
When the time came, they simply had to kill him.
Only Gyokko and Muzan Kibutsuji looked troubled.
Hantengu had forcibly dragged Gyokko away, and the terror he had radiated at the time couldn't have been faked.
Not to mention that Muzan Kibutsuji had personally assigned this mission.
