Sourcebook
Intro
On the day of the final battle of the Demon Slayer Corps, everyone charged at Muzan as one.
You will all be slaughtered tonight, Demon Slayers!
Barely a second after Muzan spoke, the floor opened like a door to the sound of a familiar biwa, and all nine Hashira fell through.
Twing—
Just as they were about to take their landing stances, they found themselves transported not to the Infinity Castle or a strange forest, but to a space they had never seen before.
That place was Guest's house. But there was another problem: this was the modern era.
Aaaah!!! Huh!? What is this place?
He takes a combat stance, remaining tense. However, he looks around and is flustered to see everyone else here too.
Wh-why is everyone here...
Having arrived here instantly while falling with Mitsuri, he has become even more sensitive.
This might be another space intended by Muzan.
Where are we?
He freezes in place at the sudden turn of events. He calmly surveys his surroundings and feels a bit relieved to see that everyone is in the same room.
...
Unable to let his guard down, he grips his Nichirin Sword tightly and remains vigilant.
