Cyberpunk: Peach John

The publisher of this work, Shinchosha, is of the opinion that "Cyberpunk: Peach John" is the world's first manga comic to be entirely created by Artificial Intelligence. This will be available in Japan from Thursday, and the illustrations were made using Midjourney, an online image producer that can produce intricate images based on the instructions of the users.

In order to create the panels, Rootport from Tokyo inserted a series of text descriptions which were then edited by trial and error to make pictures which corresponded with the storyline.
