Genso Suikoden Brunch is a collection of unconnected manga, all humorous, centered around the general time period of Suikoden II, allowing it to include returning Suikoden characters such as McDohl as well as events from Genso Suikogaiden Volumes 1 & 2.

What differs Brunch from its predecessor, Genso Suikoden Alliance, is its focus on shorter comedy stories. Many 4koma comics are included in between several of the works and even stories that start off seriously are quickly turned on their head. Three pages of color artwork are included in this volume and the mangaka Message Box section returns at the end.
