poor sanji, he won't stand a chance...
still, if the Vice admiral needed an 'active' defense to resist petrification, doesn't it mean that any person who doesn't know about her ability will turn to stone? I can't see any of the SH avoiding it, and honestly, most of the big shots (Shishibukai, yoniko, admirals) either.
it seems like a really serious 'headshot' attack, very unbalanced.
