She's an engineer, a very fragile and young one (doesn't has degree but is some kind of empirical self-teaching one). And of course, she doesn't has any combat training as opposed to almost any other character in the game.
Have to say too that the mechanical arms are a little inspired in Precis, a Star Ocean character that uses some mechanical arms at her back too.
As for gameplay impact from her design, didn't thought about anything by now haha! The 4-wielding seems neat, I'll see what I can do C:
Thanks for your comment,
