Huh. I like Serah. Goofy one moment then serious the next! I wanna write with her now :3

She's only like that in an actual battle. She feels her attitude isn't going to help people, so she shoves aside her own emotions and focuses on the task at hand.

But she'll be goofy about 90% of the time, and that's what counts.
