The original 20-volume Zettai Zetsumei Dangerous Jii-san manga was adapted into the 51-episode Zettai Zetsumei: Denjarasu Jii-san television anime series in 2004-2005.
The March issue of Shogakukan’s Coro Coro Comics magazine published the final chapter of Kazutoshi Soyama’s Dangerous Jii-san Ja children’s gag manga on Wednesday.
Soyama launched the manga in 2010 as a sequel to his Zettai Zetsumei Dangerous Jii-san manga.
Sho-Pro and J.C. Staff previously produced a 25-minute original video anime adaptation of the sequel manga that was bundled with a special-edition issue of Coro Coro Comics in July 2012.
