Bouken Special cover
The Dragon Ball: Bouken Special (lit. "Dragon Ball: Adventure Special") is a one-shot magazine about Dragon Ball, released with a special Shonen Jump issue, in December 1987.
Overview
Dragon Ball: Bouken Special was released shortly after the Dragon Ball manga's 150th chapter, midway through the King Piccolo Saga, and is essentially the earliest guidebook devoted to the Dragon Ball series. It is the source for much of the extra character background information later incorporated into Daizenshuu 7. The book covers a wide range of subjects, from Dragon Ball secrets, to the manga-creating process in general, and even Akira Toriyama's love life. It notably contains a reprint of Akira Toriyama's Dragon Boy (a one-shot Dragon Ball prototype), a look at Oolong and Puar's school days, and Q&A with Akira Toriyama.
