Kill La Kill is a different type of anime from the usual ones that seem to be too cute with pastel themes. This series is about a character transferring schools in order to investigate about the person who has murdered her father. The theme itself is already a bit dark so if you download this wallpaper theme, you can expect that the colors will be dark as well. This can be a good situation for you given the fact that dark colors fit well with almost everything. The girl seen on screen smiles at you but deep inside that smile is the desire to find out the truth.
