Arashi mean storm, I’ll let you search for the name of the chapter where Zoro and Mihawk have their first duel.
Arashi was killed by a pirate, the question is, was it a random one or Mihawk himself ? (I guess it will be so cliché to make Mihawk the one who killed Zoro’s dad)
Pinzolo mean « snake eye », which is a gambling term, Fujitora and Rayleigh both like gambling, what is the relationship between good swordsmanship and gambling ?
Furiko mean « pendulum », is it another wano lady associated with time ? Or gravity ? Or both ?
Fujitora seems to have a relationship with the names of both Zoro grandparents.
