Dragon Ball Daizenshuu 4: World Guide
Introduction by Akira Toriyama
It seems that the fourth volume is a Dragon Ball
“world guide”. I think that the staff all worked very hard, particularly on the buildings’ layouts, the maps, and whatnot. On top of just sloppily drawing things by the seat of my pants, there are many things that not even I had precisely determined. Weren’t they a bit fed up with how things didn’t come together consistently? I’m very sorry.
— Akira Toriyama
