Yeah, I really like Fuuka. She's like the mom of the group. "Old spirit in a young body" comes to mind. Her voice actress in Persona 3 FES really gave me that impression.
Actually.... the entire voice acting for Persona 3 FES was amazing. I can't think of one person who sounded bad.
Good English VA is possible!
Fuuka is... not what most people would call good voice action. She got better in P3P, but they didn't fix her original takes and by that point the damage was done so she got replaced by Wendee Lee in PQ.
Now why Atlus didn't just use Wendee Lee in the first place I'll never know, she could've just used the same voice she did for Sera and it would be way better received.
