Wolverine comes back to the mansion to discover that the Silver Samurai had captured the X-Men. Having been defeated by Wolverine a few years ago, the Samurai forces Wolverine to fight him to death and regain his honor, in order to officially become a Yakuza clan leader. The odds are stacked against Wolverine as the rules of the duel restrict him from using his claws, and he has long since forgotten how to fight with a sword.
