More than a hundred years had passed since the last gathering of the Upper Ranks.
In the eyes of the Demon Slayer Corps swordsmen, these Upper Ranks were an extremely terrifying and united group of demons.
They probably assumed the Upper Ranks kept in frequent contact.
That they launched group operations at the drop of a hat.
In reality, though, things were very different.
These so-called colleagues hardly ever saw one another.
Almost all of them stayed within their own territories. Never mind visiting one another-they barely crossed paths.
They rarely even met with their boss, Muzan Kibutsuji.
Let alone all gathered in Infinity Castle like this.
And now.
Like an enthusiastic senior colleague at work, Doma was doing his best to liven up the atmosphere.
But aside from Upper Six and Upper Five.
The other two paid him no attention whatsoever.
Yes, that mainly meant Akaza and Kokushibo.
One rested with his eyes closed, while the other simply treated him as though he were invisible.
Doma did not seem particularly bothered, though.
He turned to Akaza with a smile. "Akaza, I heard you took quite a liking to a Demon Slayer Corps swordsman not long ago?"
Only then did Akaza give Doma a cold glance.
As though looking at something filthy. "None of your business."
Doma's smile grew even brighter. "But I heard from Lord Muzan that you fought him for a long time and still couldn't defeat him."
At those words, a vein began to throb at Number Three's temple.
Yet Doma kept adding fuel to the fire.
"He seemed to be a very talented swordsman?"
"Could it be that you deliberately let him go because you admired him, Akaza?"
Number Three vanished from where he stood.
A heavy punch faster than sound suddenly slammed into Doma's chest!
