Legend (伝説, Densetsu) is the twenty-fourth and final episode of X/1999.
Fuma kills Nataku to make his flesh regenerate his own. Kakyou reveals that the future always showed the Dragon of Earth as the winner no matter side would Kamui have chosen. As Kamui goes to the Tokyo Tower for the last battle, Kakyou sends Hokuto's soul to Subaru. Hokuto states that while she and Seishirō will live inside him, he still has something to protect. Kamui starts battling Fuma, now willing to kill him. In the fight, Kamui's sacred sword is broken by Fuma's which impales his left clavicle. Fuma then tries to finish him, but Subaru receives the attack and escapes with Kamui. A dying Subaru urges Kamui to accomplish his wish, and Kamui returns to Fuma. He is once again impaled by the sacred sword, and states that while he sacrificed his life, Fuma will inherit his will. Kamui's body turns into a barrier that reverses the damage by the Dragons of Earth, while Fuma returns to his original self and Subaru appears safe. Later, Kakyou states that Earth's destiny changed, and accomplishes his wish of joining the late Hokuto.
