From Software announced their massive Dark Souls art book will be available in Japan on March 31. When we first heard about the Dark Souls Design Works it was slated for release at the end of February.

This book has concept art for monsters, NPCs, CG art, and illustrations from the game’s dark fantasy world. Another highlight is a 30,000 character interview with five key people. Enterbrain will sell the book for 2,625 yen ($32).
