From the publisher:

An endless flow of imagination - a journey to the creative fountainhead that unravels the Kantoku brain! An anniversary collection of rough sketches that touches on the origins of Kantoku's work!

It's already been a year since the release of the 20th-anniversary art books "Kurumi" and "Shizuku" -- Kantoku-sensei, the godly artist in the world of illustrators, continues to fascinate and excite many people by working in a wide range of genres, from media works such as TV anime and light novels to original works!

Focusing on original works such as "Kurumi", "Shizuku", and "Nagisa", as well as reprints of works from the rough sketchbook series that were released in the past and were very popular, this book also contains plenty of rough sketches and line drawings that are being published for the first time! Based on the theme of "experiencing the real texture of the creations" of the works of the sensei, the main gallery has been divided into two parts, a "monochrome part" and a "color part", and the paper and printing method used for each has been changed to bring you a more realistic texture and atmosphere of the rough sketches and line drawings. The popularity of Kantoku-sensei, an epoch-making artist in the illustration industry whose popularity is now not limited to Japan but has excited the whole world, is a memorable book that touches on the "origin of creation (rough sketches and line drawings)" overflowing with "imagination". Please enjoy it!
