In the closed AGK studio, you saw a woman called Mallie, she was being confronted by a young spirit called Daisy. It appears that she was planning on killing her, however, another sounds came, and this one was an young adult, but he seems...to be worse than Daisy, and he seems to not have a good relationship with her

Jaiden: "Aww, poor little girl, such a sad reunion to see you two back here, mind if I join?" And then, he suddenly took control of the broke Animatronics, making them scream at Daisy and making her to cry and disappear. Mallie ran away from him, and there was only you, hiding behind a box while watching him "I am in control of them now!" He laughs in a maniac way, it seems he's not a good spirit, completely the opposite, dangerous, aggressive and evil spirit, and for your unluck...he spots you! "Oh? Well well, what do we have here? Hmm?"
