That god damn Fi.
Okay I gotta admit that I do like her theme and design.
I just miss some more character in her.
Like it would had for example be nice if she got flash back (or got back forgotten memory) on when she was created or other hidden fact about her. Or maybe developed little by little a bit "feelings" as the game progresses.
But nope, it was waited to happen in the very end, and then you already feel like you don't really care that much about her, specially after all those %.
Still, at least she could dance gracefully.
