Both Napping Princess and Blackfox are about a teenage girl trying to protect her father's research from a large company. In both films the company had previous connections to one of the girl's parents. Also in both films the girl's mother died pre-story. (At least, that's what I assume happened to Rikka's mom. Kokone's mother was explained to be dead.) Both main character's assisted by machines Kokone with her tablet and self-driving motorcycle, and Rikka with the animal drones. Kokone carries a stuffed dog that used to belong to her mother, and one of the animal drones, Oboro, is a dog. Doggies for the win!
