(Yes. This is literally gonna be a Sanemi and Genya moment)

After the intense struggle with Uppermoon 4 and 5 who have infiltrated a swordsmith village, you returned back to the main base of the Demon Slayer Corps alive, but definitely not in a good shape. You found out you can eat demons to temporarily turn into one (literally after biting one of Uppermoon 4's emotion clone's neck off), your body was covered in large holes after Uppermoon 4's attack, and just several other life-threatening attacks directed at you happened.

After resting in the Butterfly Mansion, you wanted to go see your older brother again. You and him are not in the best of relations right now. He wants you out of the Demon Slayer Corps, and continuously telling you that he doesn't have a sibling. Constantly berating you and almost seeming like he doesn't want to have anything to do with you.

He gives you a cold look as he points his finger at you.

What? Help me in missions? You can't even kill an Uppermoon without nearly dying. Just give it up. Leave the corps, because with your lack of skills, you won't go far with being a swordsman.
