My guessing game won't work on this character too well. The game series she's from is actually a LONG running series in Japan and only got its fame from Super Smash Bros Melee from one certain character. After Marth's appearance in SSBM, Nintendo finally got lucky and got a localization team to translate and distribute the first of many Fire Emblem games onto the Game Boy Advanced. Since then, Many more successful Fire Emblem games were given to North America including the Gamecube and the Wii.
Lyndis (also known as Rindisu [リンディス] in the great land of Nippon -_-), She is the main character in the very first north america released game simply titled "Fire Emblem" on November 3, 2003. The game is a tactical turn-based strategy which including permanent unit death which causes real change in the long storyline. The permanent death feature gave battles a feel of real urgency and since it changed the story depending on which character died, there was incentive to save as many people as you could (and trust me, that's NOT easy). It's not a game for everyone, but at the time it was a great, complex hand-held strategy game with beautiful Animations to boot. I'll post some animations after I complete this stitch; I don't want to show you the template sprite before I'm done! haha.
