Ur fighfing Muzan.

Yup. You are fighting Muzan. You can choose why. No this not an argument, you are fighting.. To the death. I think the most effective reason to fight with him is to comment on his overall health and how he looks health wise. I remember seeing an episode where he got really aggressive because said he was pale and looked like he was about to die. I suggest that but you don't have to do that. Also ur a demon slayer thats related to whoever you want, you can even be related to him, or be a character from the series, or be ur OC that you created. BYE MY KNY CATS!!!🐈 Also you can add anyone else 😉 ( THE PICTURE IS HOW HE LOOKS AT YOU )
