@THE MOST ANCIENT DREAM They look really alike. Plus the psychotic tendencies. The biggest hint is her being involved with the demon worshippers. The way she sacrifices her brother.
@MissFujoshii_ she isn't involved with the demon worshippers. She used her witch skill to do what she did to her brother. She is evil but she isn't dyeing her hair red and acting like she just met her own brother for the first time a few months ago. There are no connections to the slaughter queen. Besides the slaughter queen was caught and incarcerated for a time. If she was the slaughter queen she wouldn't have been walking free like she was meeting and coaxing her brother to shame the MC.
