The first art book by illustrator AU, who has amassed more than 453,000 followers on X (as of February 2026).
This volume features approximately 130 illustrations, including works from AU's two signature original series--AU World and AU Orphans--alongside a wide range of other creations. The cover illustration has been specially commissioned and newly drawn exclusively for this collection.
AU is also known for creating book cover illustrations, designing Craft Essences for the smartphone game Fate/Grand Order, and serving as the character designer for Saburo Kunimune in the smartphone game Touken Ranbu. Original artwork from these notable projects is also included.
The appeal of AU's illustrations lies in the harmony between crystalline light rendered with extraordinary precision and richly textured surfaces brought to life through meticulous detail, all woven into immersive and compelling worlds. In addition to showcasing the artist's representative works, the book also includes an exclusive interview, detailed making-of features, and commentary on the featured characters.
