Now this is a scary thought... many Wolverine Ronins are on the loose. All are left as Ronins when their master shogun is dishonorably killed. One of the Ronins has been bought out to eliminate any possible revenge killing, but Wolverine Ronins do not die a normal death.
With this new take of the Wolverine Ronin we get a great environment for his further alienated adventures.
This is a good start for an old character.
