I was thinking of an antagonist for the Wano Arc and man you sure did nailed it. It fits, the 7th shichibukai, Wano Arc, samurai antagonist, cursed swords, Kuinaand Tashigi, and an introduction for Kaido. Great theory @Vandenreich-senpai.. Kudos! P.S. do you have a theory for the 3rd admiral that replaced Aokiji/Akainu?
