My name is Kami Chiyo, and I am a second-year student at Chengnan University of Electrical Engineering. I have a friend named Echizen Nanako, and because of her I got to know a bunch of abnormal junior high school students.
The background of the heroine comes from the novel "Machine Madman" written by Japanese female novelist Hiroshi Arikawa.
It's a combination of a mechanical maniac and a net king.
