Worst waifu.
Fight me Philius.
She's... in words, a disappointment. She's fine in Birthright, a part of the problem in Conquest, and needlessly, overly mysterious in all three routes. (Seriously you guys LANDED IN VALLA IN CONQUEST WHY DIDNT YOU JFKNFDH)
As far as other things...
Design wise, she's lovely, voice wise, she's beautiful, support wise, she's actually pretty interesting.
But main plot wise, dear lord.
