What is an innocent sounding girl name?

For the record, the main character is the reason of the horror for the story. I want her to have an innocent name because I like it when the character's name conflicts with the character's personality.

For her apperence, the girl is a very short (5'3), pale girl with white hair (part of her back story as to why), and she lines her eyes darkly. She always wears a plain white flowwy shirt that goes to her knees with jean shorts underneath (that at this point is stained with dirt and blood). She's constantly barefoot, and has long, harsh nails almost like claws.

I know it sounds cliche, but the story is better, trust me.

She basically wishes to kill the entire human population because humans are destroying the planet and causing innocent creatures to go extinct. She ran away from civilization and refuses to use anything man made. She kills any human she can find and doesn't care who knows or who sees. She's not afraid of the law of humans because what gives them the right to decide laws? She loves animals and plants (a little too much), and often sleeps in abandoned animal dens, trees, or caves.
