Nice! She looks like a character I'd really like. Also, I really like the story of how you ended up liking her. Isn't it weird when that sort of stuff happens? :D
I wanted to tell you, have you played FE6? Because it has a character who looks a lot like Cherche:
Milady. I think they don't share much personality-wise (except for the fact that they both consider wyverns to be cute, but that might not be too weird, heh), but they're both women with red hair who ride wyverns in Fire Emblem, so I thought this could interest you. :)
