In 1945, Logan is held in a Japanese POW camp near Nagasaki. During the atomic bombing of Nagasaki, Logan saves an officer named Ichirō Yashida by shielding him from the blast. In the present day, Logan lives as a hermit in Yukon, tormented by hallucinations of Jean Grey, whom he was forced to kill to save the world.[nb 2] He is located by Yukio, a mutant with the ability to foresee people's deaths, on behalf of Ichirō, now the CEO of a technology zaibatsu. Ichirō, who is dying of cancer, wants Logan to accompany Yukio to Japan so that he may repay his life debt. In Tokyo, Logan meets Ichirō's son, Shingen, and granddaughter, Mariko. There, Ichirō offers to transfer Logan's healing abilities into his own body, thus saving Ichirō's life and alleviating Logan of his near-immortality, which Logan views as a curse. Logan refuses and prepares to leave the following day. That night, Ichirō's physician Dr. Green (also known as Viper) introduces something into Logan's body, but Logan dismisses it as a dream.
