Haunted by his past and the immortality that defines his existence, Logan, better known as Wolverine, isolates himself in the vast wilderness, grappling with the loss of his love and the burden of his enduring life. His self-imposed exile is disrupted when he is located by Yukio, a skilled swordswoman with premonitions of death, who has been sent by Yashida, a dying billionaire industrialist from Japan. Decades earlier, Logan saved Yashida's life during the bombing of Nagasaki; now Yashida seeks to repay his life debt by offering an impossible gift—the chance to become mortal.

Upon arrival in Tokyo, Logan is drawn into a complex web of power struggles and family conflict. He meets Mariko, Yashida's granddaughter, whose life is threatened by factions seeking control of Yashida's corporate empire. Bound by a sense of duty, Logan chooses to protect her while increasingly experiencing vulnerabilities he's never known before. As threats escalate and trust becomes scarce, Logan confronts not only human adversaries but also his own internal battles, as he questions the nature of his existence and the price of the eternal life he's lived for so long.
