Let me avail myself of thy anime/manga/game knowledge...

So, I have been looking for a FC for a water-goddess type character for some time now, and I have not had much success yet. For species, this character is going to look human (although having a few fish-like qualities might be interesting–they just have to be pretty vague). Preferably she would have blue hair, but green or turquoise could work as well. Eye color is not necessarily a deal breaker; I think just about any old eye color will do. Likewise, skin color is not a major issue. While I've typically envisioned this character as fair-skinned (especially with blue hair), tan skin might look good as well, I don't know. 

With that said, age is fairly important when it comes to this character. She's in reality very old, but has the appearance of a young woman, so child FC's will not work (unless there's a good amount of art of that child as an adult). I'd also appreciate it if the FC isn't the cheeriest person–someone who's usually serious, irritated, or closed-off would be great. 

The FC's outfit is also pretty important. I'm thinking she would wear something that's both regal-looking, yet somewhat revealing (she does come from the ocean, after all). If that isn't easy to find, civilian clothes would be fine as well. It might actually be more interesting to do it that way, since this character is going through a lot of inner conflict between what she's always known and believed, and the realities of the modern world. 

Finally, there is just one FC that I am pretty sure I do NOT want, and that is Juvia Lockser from Fairy Tail; this charrie's abilities resemble hers just a little too much for comfort. 

Hopefully this isn't too much to work with; let me know if you come up with anything! Thanks!
