The elfman tells his sister that he can't defeat the demon because she's possessed by demons. He tells her that he's the one who defeated the demon in the church, and he blames her for everything that's happened to his family. He's not the only one who's been cursed by demons, he says. He also points out that his sister and brother-in-law have taken over the guild, and the only reason they're doing so is because they've been taught how to do magic by the elfman and his sister. He wants to get rid of his sister pronto.
