Sci-Fi Trans-Human Hero

Celene Fisher is a fifteen year old girl who lives alone in a house at the edges of Happy Harbor. She goes to school, but doesn't really make friends. She's happy though, here and far from her parents. Sometimes, when someone bumps into her, she feels harder than she should, but that's just the overactive imagination of teenagers. She doesn't do sports or exercise, but is always in shape, no matter how much or how little she eats. Nobody has seen her parents, apparently they're always busy at their jobs in Gateway city. But nobody really cares all that much, she's just a normal girl living in Happy Harbor.
