Autumn is the adopted daughter of Ranpo Edogawa, the probably most intelligent detective in the world, and Edgar Allan Poe, a novelist. Her parents are gay, and they take good care of her. Autumn herself is also a very creative person, yet she is very shy and tends to get panicked around strangers or crowded places. She is very anxious as doubts herself often. She's also a trans boy, but she is too scared to tell anyone, in fear what they might think of her because of it.
