Gah, totally forgot about this thing...

Not sure where Seth is lately, though he could've been just quietly observing the forums in the background, logged in anonymously...

Anyway, the characters I have are(just brief descriptions, as I don't have them that well developed...):
Andromeda: A 23rd century teen who's accidentally landed in the 21st century via the time machine she'd rented... She doesn't trust anyone in the current century as of yet, so she's been trying to keep things on the down low and goes it alone with the tech she'd brought back from her time(albeit well hidden tech lol)...
Amethyst: A somewhat rebellious mermaid who swam away from home and, thanks to a tsunami, got marooned on the shores of Japan just outside the city of Tokyo. A sweet teenager(female, next character) found and befriended her, agreeing to keep her true identity a secret from prying eyes who could potentially exploit her... Has light purple hair and scales of the same color on her outer thighs and ankles, so she has to keep them covered up with the clothes her new best friend gives her...
Nicole Ichuga: A teen who lives in Tokyo and rescued Amethyst, quickly becoming her best friend. She has the appearance of a punk rocker, but her personality couldn't be more different... She can also be found doing things around her part of Tokyo to help people out who are in need... Although she has a sweet disposition, she isn't afraid to stick up for people she loves when trouble arises, plus is willing to stand up for what's right despite the potential consequences...
Yuki: The most popular girl at Nicole's(and now Amethyst's) school, who tends to pick on those she deems inferior to her... Once Amethyst shows up out of seemingly nowhere, she gets jealous and sometimes tries to sabotage her, but Nicole always steps in before anything bad happens...
Umi: Yuki's sidekick and most loyal companion... Tends to stick her nose where it doesn't belong, is rather dim-witted, and can be a bit of a klutz sometimes... Being such a busybody can get her into trouble sometimes...
Mori: Another girl in Yuki's group, but secretly wants out of it... She tends to be overly cautious a lot of the time, and is rather intelligent, as well... The only reason Yuki keeps her around is due to her(Mori's) intelligence... Mori tends to be rather secretive, just like Amethyst is, and the reason is because she and Amethyst have the same secret...
Okay, that pretty much covers my characters...

I bet they can easily be improved somehow, though...
