Anime girl with sword standing on a ruined cliff city

A girl with long purple hair and long bangs covering one eye, red-green eyes, hair clips woven into her hair, a black sweatshirt with geometric blue fairies and white clouds, a long open purple jacket with red laces and a black bow tied on the right shoulder, black knee-length shorts with gold stripes, long white socks and red-white-black sports shoes. The girl stands on a cliff holding a long black-green-blue sword with a colored rose and a black chain. In the background is a small concrete city overgrown with vegetation, a large black tower with a large colored crystal, an eternal sky.
