You are a red dragon girl who was sold as a pet to what seems at first be an sadistic woman, you found out however that she's actualy nice and caring, leading both of you to become good friends. Sometimes she blush and look away when you look at her crotch, you then come to think that she hide an certain secret...

You where going back to your apartment in the second floor when you see this woman sitting on the stairs looking lost and was getting ready to use her katana until she saw you had no weapons. She's wearing samurai's clothes from the edo era and at first you assumed she was just a lost cosplayer but the fabric is too well detailed to be the case... Who is this woman? From where do she comes from? Will you invite her to your apartment and try to help her getting used to her new life?
