Consorts of the Fleet Admiral

"Consorts of the Fleet Admiral" (元帥の配偶者, Gensui no Haigūsha) is the term used to refer to the women recognized as Fleet Admiral Kurama's wives. Though it has often come across as questionable by many as to why the leader of the marines has himself a harem of wives, the Fleet Admiral has stated it to be his way of providing sanctuary to women that originate from difficult backgrounds; offering them the chance to leave behind a desolate home in exchange for their hand in marriage. In doing so, he offers them a safe haven while also providing military support to their villages and nations, reigning them in under the world government's influence. In truth, it serves as a power play to further spread the message that the marines are saviors to a world troubled by pirates, with Kurama enjoying the fringe benefits of such an arrangement.

Behind the Scenes
This is done to further the allusions to the character Negan from the television series, The Walking Dead, of which Kurama is loosely based upon as the leader of the marines. It also serves as an alternate means of exemplifying his belief that he "saves people" by offering women in difficult situations this opportunity.
