Chapter 936 introduced this Big Character who stole Zoro´s Shusui. Some people have related him to Benkei from japanese folklore. He talked about returning the Blade to it´s rightful place (Ryuma´s grave). But he also threatened Zoro to die by the hand he stole from. Perhaps this Benkei character is related to Ryuma. But more importantly, what does the editor note foreshadow about Shusui´s fate? Was it the fate of the sword to be stolen and brought back? or what else? Could the sword be cursed?
