十隠 カンナ

Childhood friend of Kisaragi. She, like Kisaragi, is a very gifted scientist, yet her inventions tend to go awry. She and Kisaragi planned to conquer the world when they were kids, yet when Kisaragi gave up that dream to become Chitose's mother, she tricked Chitose and his family to her secret island so she could convince Kisaragi into joining her, yet she falls in love with Chitose and decides to learn the emotion which caused Kisaragi to give up on their dream. She now tries to "capture" Chitose, using both casual talking and technological force.
