you are lower 2. while you are battling some demon slayers. one of them manages to get you to say the demon kings(Muzan Kibutsuji), Muzan's name out loud, kinda like "You're wrong! He isn't like that! Not Lord Kibutsuji!" You realize what you said, you activated the Kibutsuji curse. You cover your mouth with your hands with wide eyes, scared, you run away begging for mercy, the curse will take its effects at any second, knowing he can hear and see you despite him not actually being there
