As an alternative to the Kitsune upgrade, consider adding a more DPS oriented upgrade to Yozora. I think it'd be badass.
#Consider: Yozora with a sword (third upgrade path)

Maybe instead of boosting the aura she could get enhanced attacks after a dodge?

The aura is a signature move of the Yozora character. Why not amplify it?

Because auras tend to be overall really strong while feeling lackluster

Relying on them makes you weak during single-target waves, same as any AoE
EDIT and waves like 13 with few but tanky units

Maybe reduce the range to only enemies in melee range? Would encourage the player to build "Yozora's with Swords" next to one another like wolf packs or dryads, in order to maximize the effect of their closer-range blizzard storm
A shorter range aura would enable the enemy player to counter the Yozora's by sending ranged units, too. Lizard spam and no attack-speed debuff on them means dead Yozoras...

Or perhaps "deals 200 damage in a radius, split equally among nearby enemies" if you want to remove that weakness
