If I wanted to be honest, I honestly didn't really like Fuuka. As much as I jab at the stilted delivery of her lines when she comes up, she just never really clicked for me as a personality. Her own individual arc, around Natsuki and her never worked for me the way that, I dunno, Junpei and Chidori did, or hell, even Yukari and Mitsuru. Not to mention it struck me as really unbelievable that her and Natsuki could come so close despite everything that she'd inflicted on her, although I'll admit I might have been projecting a bit of myself there. The game makes a point of suggesting she's got a really troubled home life, but doesn't go anywhere with it. She's just... I dunno, half-baked, personally. I mean, like, pretty much everyone else (besides the dog) sees their Persona evolve after finding themselves and finding new resolve. Fuuka just... gets hers. And I think that in and of itself encapsulates a lot of my problems with her.
I think I liked her more in FeMC's route.
