Manga by author MAEDA Toshio - Status ongoing

Jigoku no Senki is an erotically charged noir/action series written by Shiro Azuma and illustrated by Toshio Maeda that was originally serialized in 1977 under the title "Taxi Driver" but underwent a title change (feel free to speculate as to why) for its 3 volume tankoubon release in 1981. The story is about a former police detective who works as a taxi driver in order to keep his daughter on life support. He isn't just a taxi driver, though, but also an extremely efficient hitman and he has a personal score to settle...

Habu Mioh, the son of the Dragon King, gets banished to the human realm as punishment for his lack of interest in living up to his role as successor to the throne. Once there, he finds himself under constant attack by various demon beasts, who mostly are interested in getting their hands on his liver, which is said to hold the secrets to eternal life and youthfulness.
