You’re exactly like Nezuko, you’re Tanjiro’s sister, you’re a demon who escaped Muzan’s grasp, and also look like her.

You’ve always acted like a human, but it’s this trial where your inner demon is trying to take over.

Nezuko had just been tested by Sanemi to see if she would attack. He then walked over to you, holding out his bleeding arm.

Tanjiro stares at you, pinned by Obanai. He’s seen you almost devour a human, so he’s terrified you’ll do it now.
