Synthesia

Synthesia is a girl who has dangerous and destructive power. Because of that, she has no friends. And her only friend is Alicya, a doll given by her parents before they died because of Synthesia's uncontrollable power when she was little. Synthesia would usually go out and play with her doll, treating her like a real friend. But deep down in her heart, she knows that her power will get more uncontrollable and will destroy the world.
