Ayra ???

A Def boon actually isn't that bad on her since she is quite durable with it. That Spd bane however... is probably going to feel like death to her as she relies heavily on her great speed to make her a really good unit. Without it she wont be able to separate herself from many of the other sword users.

Definitely sadness overload. Ayra’s blade relies on her outspeeding her opponent. Unless you fight enemies with mediocre speed, she’s not going to be as effective as she can be even with a neutral speed stat.

Half sadness overload cause she's -spd(can relate, broke my pity rate of 4.50% with -spd Leif), half happiness overload cause first of all at least you got her, and second, she's still salvageable. +3 speed seal and she goes back to 40 speed, Swift Sparrow and Threaten Speed and it's a virtual 49 on initiation. +def makes her an even better tank so you could also try to buff her defense(Def Tactic buff and she reaches 40 defense).

Sadness overload; She needs to be able to outspeed her opponents.
