Six years ago, Kamui Shirou and siblings Fuuma and Kotori Monou were inseparable childhood friends. After the sudden, gruesome death of the Monou siblings' mother, Kamui was taken away from Tokyo by his own mother. In the years that passed, the two lived peacefully while Kamui strengthened his innate telekinetic abilities. When his mother passes away in 1999, her dying wish prompts him to return to Tokyo to face his "destiny."

When Kamui reappears in the city, his attitude has taken a drastic turn, and he displays the growth of his powers through violent confrontations in the streets. Various opponents come after him asking if he is "Kamui," but they seem to be demanding something far more significant than his name. These fighters represent two opposite factions—the Dragons of Heaven and the Dragons of Earth—who each wish to recruit him to their cause. Piecing together clues about the apocalyptic "promised day," Kamui realizes that he holds the fate of the world in his hands. Depending on which group of Dragons he allies himself with, he can either choose to save the world—or end it.

Manji is an infamous swordsman in feudal Japan who is known as the "Hundred Man Killer," as he has killed one hundred innocent men. However, there is something far more frightening than his ominous reputation: the fact that he is immortal. This is the handiwork of eight-hundred-year-old nun Yaobikuni, who placed bloodworms capable of healing almost any wound in Manji's body. 

To atone for his crimes, Manji resolves to kill one thousand evil men. Yaobikuni agrees to this proposal, saying that if he succeeds, she will undo his curse of immortality. Soon after this promise, Manji meets Rin Asano, a 16-year-old girl who requests Manji's assistance in killing those who slaughtered her parents.

Initially reluctant, Manji refuses Rin's desperate plea. However, owing to her evident lack of strength, Manji changes his mind and agrees to protect Rin for four years. With this partnership set in stone, the two embark on a perilous journey of bloodshed, vengeance, and redemption, each to fulfill their own life's cause.
