I was just wondering if there is a rank system for vizards and what ranks are still available

the only ranks for vizards so far are

VIzard Commander

Elite vizard

Vizard

i have the vizard commander rank and im not sure how many elite vizard there are allowed to be, but i hope you join the ranks

What types of weapons are allowed for vizards, and how many swords are allowed for sealed and shikai?

zanpokuto are any type of weapons, always the best fit for the character's style and physique.... i have two in shikai but one in sealed...... so i dont think there is a limit, but i doubt you can use more than three, unless you have more arms >.>
