100 Sleeping Princes and the Kingdom of Dreams Official Artbook Vol. 2

100 Sleeping Princes and the Kingdom of Dreams Official Artbook Vol. 2 explores the characters, costumes and stories developed during the game's first three years. Detailed profiles cover 21 princes introduced after the March 2016 Prince Award, from Toya to Inami.

Nineteen short stories bring together new pieces based on readers' suggested conversation topics and stories previously published in B's LOG. Standing character illustrations show costumes from in-game events, accompanied by the development team's explanations, while rough sketches reveal how the princes and their outfits were designed.

Licensed illustrations and a developer interview reflecting on those first three years complete the collection. Its five sections move from prince profiles and short fiction through in-game costume features to the illustration gallery and additional editorial material. Published by Kadokawa, this Japanese-language A4 volume contains 192 pages.
