Beginning in December 2016, popular fan artist dragongarowLEE received his own official spin-off manga published by Shueisha on the “Jump Plus” digital platform. “Dragon Ball Side-Story: The Case of Being Reincarnated as Yamcha” (ドラゴンボール外伝 転生したらヤムチャだった件) was announced to run for three chapters, and is named in reference to Fuse‘s “The Case of Being Reincarnated as a Slime”.
ドラゴンボールに超とんでも外伝が登場!主人公はまさかの…アイツ!!最強を目指し、とてつもない修行にチャレンジする…!?
Dragon Ball gets a super-outrageous side-story! And the main character is… him, of all people! Aiming to be the strongest, he challenges himself with stupendous training…?!
Taking to Twitter following the series’ debut, dragongarowLEE stated:
This time they’re letting me draw a Dragon Ball side-story manga for Jump Plus. I was worried about what kind of response it would get, but I was surprised that it caused enough of a stir to trend on Twitter. Thank you everyone for reading it! And replying on Twitter (^^) Sorry for keeping it a secret until now.
My editor first gave me the plans for a manga about reincarnating as Yamcha, and I used that as the basis to make my rough draft and original manuscript. Like always, I did everything myself, entirely analog (^^) It’s good that even in this day and age I managed to get by even without a good PC setup.
By the way, it’s planned for 3 chapters total, and I’ll try and have the next installment out by next month, so everyone looking forward to it, please hang on for just a bit m(_ _)m On the official account they went and wrote “he challenges himself with stupendous training?!”, which kind of gives me a higher hurdle to clear lol.
A text splash on the final page of the third chapter confirmed a collected print edition scheduled for November 2017, which was released in both physical and digital editions with additional content.
