Illustrator AU (AU, 453K followers as of February 2026) debuts with their first art book.

This book features approximately 130 illustrations, including two of AU’s original series, AU World and AU Orphans. The cover is a special, newly drawn piece created exclusively for this art book.

AU gained major attention for illustrating music videos such as “Gishin Anki (Cover)” and “Fight Song (Cover)” for Nijisanji VTuber Kuzuha. AU’s work includes novel cover illustrations, concept artwork for the mobile game Fate/Grand Order, and character design for Saburou Kunimune in Touken Ranbu, among many other achievements. Original artwork for these projects is also included.

The appeal of AU’s illustrations lies in the combination of delicately rendered, translucent light and richly detailed, textured elements, creating a compelling, immersive world. This art book focuses on AU’s signature works and also includes an author interview, illustration-making notes, and character explanations.
