I think After Years made Rydia to be her real age again but in IV she really ages in Land of Summons. So yeah there is nothing wrong with Edge hitting on Rydia. I think Edge was cool, even though he sometimes was brash he also was honor code honoring ninja. And those types ninjas are coolest of them all.

Blitz was great Ninjutsu and 2 katanas were also good damage dealers. Steal sucks and so does most of Ninjutsu ( or is it Ninjitsu?).
