193X year. Before World War II, Kasumi Kenshiro, the former sixty‑second heir of the ancient martial art Hokuto Shinken, previously known by the nickname "Yan Wan" — "King of Death," who kept peace in the "City of Demons," hid behind the persona of a modest and absent‑minded literature professor at a small Tokyo women"s college. He dreamed of a quiet life and anonymity, while fighting bandits and drug traffickers, but the death of his beloved and former comrades forced him to return to Shanghai to fulfill his destiny and avenge those who were dear to him.
