On Shonen Jump's official website, aside from spin-offs that were announced earlier coming from Naruto, One Piece and Katekyo Hitman Reborn, they announced that Naho Oishi's Dragon Ball spin-off, Dragon Ball SD will be part of Saikyo Jump!
The manga will feature the misadventures of Son Goku, Krillin, and other friends from the original story (Hence, their outfits are those when they first appeared in the manga/anime). The website hints that another popular character will also appear in Dragon Ball SD.
Saikyo Jump will be released in Japan this December 3 along with a poster for next year's Jump Heroes Film, a stereoscopic 3D double-billing of One Piece 3D: Mugiwara Chase and Toriko 3D: Kaimaku Gourmet Adventure!!.
