Please understand that this is managed by amateurs. This book focuses on "background originals," a material used in the animation production process. Background originals are materials created in the preliminary stages of background art production. The quality of the background originals directly affects the quality of the background art itself. Though they are not always noticeable, they are essential materials that support the world of the work. One of the creators who works on such background originals is Satoshi Takabatake. We hope you enjoy the beautiful and complex world of background originals, drawn with the precise and detailed lines cultivated during his time as an assistant on the manga "AKIRA," and utilizing digital technology.
