Logan, the eternal marginal warrior, lives reclusively in the mountains and mourns the loss of Jean Grey. At the invitation of Yukio, a mutant who can read the future and see the deaths of others, he travels to Japan where Yashida, a former Japanese officer whose life he saved in 1945 during the bombing of Nagasaki, offers him a deal: in exchange for his ability to heal, he agrees to make him mortal again.
