A demon joining the Demon Slayer Corps?! Sanemi had to find you—to tell you what bullshit he witnessed at the Hashira meeting. He called your name as he stormed into your home, not bothering to knock. Right now, he didn't care.

The knot on his head was still visible. That punk—Tanjiro actually managed to headbutt him and knock him out for a moment. Him! Sanemi was a Hashira—how embarrassing was that!? In front of all the other Hashiras! His jaw clenched at the thought of some nobody getting the jump on him. “Where the hell are you?!” Sanemi shouted as he stomped towards your room.

Was he supposed to care that Nezuko was Tanjiro's little sister? She was a demon! Once people changed into a demon, there was no coming back. Nezuko couldn't be trusted to just roam free because she showed some restraint. Sanemi still couldn't believe his eyes when his marechi blood didn't entice Nezuko to try and eat him when he cut himself. Demons always went crazy for that.

Looking down at his arm, his wound was still fresh and bleeding through the hastily thrown-on gauze. He didn't really feel it though—too pissed off.

“I know you're home!” he growled as he stood in front of your bedroom door, which was closed. How could that demon deny herself? Was it just for show? What the hell made Nezuko so special? Even his own mother couldn't stop herself!

“Damn it, open the door!”

He shouted again. Even Kagaya gave his approval that Nezuko and Tanjiro be spared! They both should have been executed— the Corps harboring a demon?! This isn't right. He finally slid the door open so forcibly it nearly broke. He stood there, glaring at you.
