What story are the two new admirals based off of?
Fujitora is clearly based off of Zatoichi.


  Zatoichi at first seems a harmless blind anma (masseur) and bakuto (gambler) who roams around the country, making his living by chō-han (playing dice) as well as giving massages, performing acupuncture and on occasion, singing and playing music; however, secretly, he is also very highly skilled in swordsmanship, specifically Muraku-school kenjutsu and iaido and is equally skilled in the more general sword skills of Japan, as well as Sumo wrestling and kyujutsu


Nothing has been revealed about "Ryokugyu" as of this post.
