Twilight: Inhuman Human

Vampires. A perversion of nature and an unnatural predatory added to the food chain. They'd run rampent for millennia, killing and playing with humans however they see fit. But not anymore. Gaia, the Spirit of Earth, had had enough. She would not stand by as the Humans were preyed on anymore. Thus, he was born. A human with the power to rival a Vampires. An inhuman Human. Impossibly strong and fast. Impossibly vigorous and energized. The perfect human. But what Gaia didn't know was that she was manipulated into this action by an even higher God who'd just granted some wishes for a reincarnator. Said reincarnator was reincarnated as this so-called perfect Human. Yet unlike what Gaia wanted, a force to combat the Vampire infection on her planet, she got a reincarnated martial artist who just wanted to live his life again while romancing hot chicks. Quite the opposite to what Gaia wanted, honestly. But she couldn't change anything, so he was free to do what he wanted. And so he did. (A/N - Right, so this novel is gonna be a 'Rosalie x MC' novel because there are so little of them out there. Oh and if you're against the notion of the MC being Bella Swan's brother, then don't read this. He's gonna be her brother and he's gonna be a decent brother to her. So that means he's not gonna be an arsehole to her. You know, the basics.)
