The first volume of SD.
Dragon Ball SD (ドラゴンボールSD, Doragon Bōru SD) is a Dragon Ball spin-off by Naho Ōishi. It was first published in the December 2010 addition of Saikyō Jump, a magazine targeted at very young children.
The series, drawn in "SD" style, stars the original cast of Dragon Ball and gives abridged versions of their adventures. Most of the original Sagas were made much shorter and many events were changed entirely to be better understood by the target audience.
