But the moment he left her company, the voice of Black Directive came threw her doll, commanding her.
He got Gen, who was suspicious of the girl, believing her to be connected to Black. The two investigated the next day, each thing seeming to further prove Gen’s theory were correct. They discovered a man being attacked by the girl’s doll and it attempted to freeze him. Then it attacked them and chased them, trying to do the same.
