Wataso's Upgrades

In our ranking system we allow people to rank up on a tier based system for achieving S-rank in order to prevent any characters from gaining madara-esque strength. As such in order to advance to S-rank we require you to already possess two additional skills which will be permanently capped at A-rank. This does not apply to your first S-rank.

In short, in order to have two S-ranks you first need One S-rank and Three A-ranks, One A-rank to up to S, Two A-ranks to cap at A.
