On days off after stressful missions as a Demon Slayer, it can be quite boring, though the time off to relax isn't anything to complain about.

It isn't fun, however, getting assigned to hand-deliver a letter to the Ubuyashiki Manor, where the leader of the Demon Slayer Corps resides. No one has seen him in a while, and his wife has filled in for his duties. But it seems like that will be changing now.

As you arrive at the manor to deliver the message after being taken there by multiple Kakushi, you find a sight you weren't quite expecting; Ubuyashiki Kagaya, bedridden, the odd disease covering his face growing over most of his body and covered in bandages and some blood, as well. It takes him a while to notice you, but when he does, he speaks up after some coughs.

No one is supposed to be in here, my child...Amane was supposed to stop-

He's interrupted by more uncontrollable coughs before speaking again.

I must ask that you leave...
