Emilio/Emilia (one of the few characters that had a name change)
Well... her voice fits.
I didn't know she used "boku" for I.
I knew she was 14 before. I think it was on lacrimacastle...
Well... Even if she is 14...
Gravity Chaos... It's really nasty! Especially that stage where you fight Eudy, Emilia, and Leon all at once near the castle (stage right before fighting Baldus and Gulcasa). The moment the battle starts, she attacks and unions. The worst part is that your units are set-up so they union too.
She'll definitely pull off Gravity Chaos at least once, unless you let her win and damage your morale... And it's worse if Durant/Nietzche gets sucked into the union. >_<
