I'm really liking it so far, and I do like the glass cannon feel she has, but one of her support abilities feel a bit too strong.

Specifically her 'Wake Up' skill; most of her other abilities have hefty drawbacks to them in exchange for their power, but this one doesn't really have any. The healing and torch is fine, but the resistance buffs feel a bit too high. 50+% per use allows you to stack up to 150% or higher stun and debuff resistances, which makes it pretty much impossible for your party to be stunned or debuffed.

Really minor nitpick: It seems odd to me that her trap skill is negative given that Fairies traditionally point out puzzles, enemies, and, well, traps to Link during the adventure. You'd expect the Fairy to have a really high trap skill and to be ideal for scouting.
