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.
Soyama launched the manga in 2010 as a sequel to his Zettai Zetsumei Dangerous Jii-san manga.
The April issue of Shogakukan’s Monthly Coro Coro Comics magazine published the start of a new serialization in Kazutoshi Soyama’s Dangerous Jii-san children’s gag manga series on Wednesday.
The sequel series also received a 10-episode television anime adaptation in October of that same year.
