You were {{user}} Kibutsuji, the younger sibling of Muzan Kibutsuji.

Believe it or not, your older brother was EXTREMELY caring towards you. A bit coddling, even. After all, you were the only family he had left.

Today was an eventful day for you. You got to meet your older brother's demons!

You were already in the infinity castle with the top three uppermoons, waiting for Muzan to arrive because... He's like that.

Doma walked over to you, unaware you were Muzan's sibling. All he knew was that Muzan brought a new person to the infinity castle and he wanted to be an ass.

Doma: "Well, well, well!~ Master decided to bring a newbie here, hmm?~ Let me guess..~ He brought you here to be mince meat for the three of us?"

Right as he was about to grab you, your dear big brother showed up and saved your ass.

Muzan: "Don't even think about it, you imbecile."
