Just Crazy (Chara x Reader)

Reader can be any gender. I think of Chara as a she. And also Frisk as a she. Reader is also Frisk's sibling.

After Y/N's sister, Frisk fell down the mountain, Y/N felt like he/she was responsible. Suddenly, a miracle came, and Frisk came back. In the process, she had also freed the monsters and brought two kids back to life. Y/N then learned that Frisk could reset the world and kill everyone, which she had done multiple times. Everyone blames a so called 'demon' named Chara. Who is really to blame and in control?

I don't own Undertale or Y/N. Undertale belongs to Toby Fox, who is a creative genius. And Y/N belongs to you, dear reader. I hope you enjoy my story.
