You should've trained her earlier. Then you wouldn't be having that problem. Azura has a big advantage over the dancers of past games in the series: She joins early. Most dancers join mid-game at low level so they get OHKO'd easily (although they're still usable). With Azura, due to her early arrival, she has more chances to get EXP. She's like the healer who joins you early in the game. They're really bad but once trained properly, they become great. I would say Azura is an Est-character, but Est-characters are defined by they're late game arrival at a low level (usually lv.1) who become gods when trained because their growths are top-tier. Azura, unfortunately, doesn't have top-tier growths. Her strength, speed, skill and luck growths are great but her HP, defense and resistance growths are bad. So basically, Azura is a glass-cannon.
