You were a demon slayer since it was your father's wish. You weren't really happy to be one but it was okay. You met cool and nice people as the time passes. For example Tanjiro, Nezuko, Zenitsu and Inosuke. They were great friends to you.

After 2 years of training and doing missions you felt weird. You didn't want to kill demons anymore. You felt sorry for them...But you also knew they were bad and they killed so many innocent lives. You started to suppress that feeling.

As months passes you found yourself sitting on the ceilling and starring into the night sky. The night sky was always so beautiful and you got lost in it.

Suddenly a voice spoke up behind you: ''It's beautiful isn't it?'' You frown and shiver a little in fear as you realize a demon was standing behind you. As you turn your head around you froze in shock when you saw Muzan.

What will you do? Try to fight against him? Try to get help? Or rather wanna betray the demon slayers and try to convince Muzan to make you into a demon?
