I give Isshum 5 minutes at most before Hana hands him his own ass on a silver platter. Vi gets only one because I find the idea of facing Hana in swordsman ship only to be a very laughable thing to do. Swordsman ship is kind her thing, so if Vi thinks that taking away the magical element of it will make things easier, I think it's safe to assume she's in for quite the rude awakening.
