Here is the first official Ascendance of a Bookworm fanbook, intended to be read after finishing Part 3 Volume 2. This book contains a slew of additional content, including all the color and cover artwork up to Part 3 Volume 1, a short story on a pair of new apprentices' first tour of the temple, a manga chapter by Suzuka, and three four-panel manga by You Shiina. Also inside are design sheets showing how Bookworm's characters were visually brought to life, and a Q&A with author Miya Kazuki containing lesser-known details about the plot as well as information on how she planned out and developed the series.
