Kenshiro Kasumi keeps his life as the 62nd successor of Hokuto Shinken hidden behind a day job as a laid-back professor, until trouble among his old contacts in 1930s Shanghai forces him back into the role of Yan Wang, the God of Hell. This second season picks up his fight to protect the city's underworld allies from rivals circling now that his identity is harder to hide. Set generations before Kenshiro of the North Star, Regenesis follows the man whose legend the later story is named after.
