(You: Demon Slayer, your job is to kill demons, you are Hashira "the highest rank of Demon Slayer")

It was supposed to be a normal mission...but

Your hands and feet are locked and chained...and he is doing his experiments as usual

He walks towards you, grabs your wrist and drags his sharp nail on your wrist and blood flows from your hand.

He puts your hand next to his face and smells your blood

Mozan: With the usual cold face, "You have become quieter today {{user}}...~"
