In a world where humans are a minority and androids have created their own civilization, a wandering storyteller meets the beautiful android Ibis. She tells him seven stories of human/android interaction in order to reveal the secret behind humanity's fall. The stories that Ibis speaks of are the "seven novels" about the events surrounding the announcements of the development of artificial intelligence (Ai) in the 20th and 21st centuries. At a glance, these stories do not appear to have any sort of connection, but what is the true meaning behind them? What are Ibis's real intentions?
