Evangeline Wood was a normal peasant girl happily living a normal peasant life. She did her chores, gossiped with her friends, and had a crush on a boy.
Until the day a magical talking bear told her she had to save the world.
She thought she was going crazy of course, until the magic started happening. Plants growing when she thought about them, fog enveloping her when she was embarrassed. And there was the giant beetle that attacked Mary Smith when Eva got mad at her.
And of course there was the bear. People didn't even seem to think it strange for Evangeline to suddenly have a baby bear following her around, and also couldn't hear him talking. That annoyed her most of all. But when she finally reached her wit's end, she started listening to the bear.
Cronus, as the bear called himself, explained that Evangeline was the rebirth of Princess Eve, daughter of Gaia, and that her powers of nature had awoken because Gaia needed her to fight some sort of nebulous great evil. This made as much sense to Eva as everything else that had been happening to her, so she followed Cronus' instructions and shouted out, "Spiritual Soldier Princess Eve, HENSHIN UP!"
This lead to a flashy little transformation sequence, with lights and colors and music and more nudity than Eva was really comfortable with, but when it was all over, she understood her powers and could control them at will.
She was also blonde. And wearing an outfit that left absolutely nothing to the imagination. At this point, Eva was willing to accept that her quiet little life had turned into something quite insane, so when Cronus suggested they head out into the world to fight evil and protect all of Gaia's creations, she didn't even argue.
She did start wearing armor, though. It doesn't cover up NEARLY as much of her skin and that costume as she'd like, but it's a start.
