This situation reminds me of when I was trying to find a certain image for, like, almost the same amount of years - before encountering it in meme form on iFunny. And it's not creepy, as we've already entered the hentai realm.
Maybe it could be Erza Knightwalker and Erza Scarlet - red hair - Scarlet has like straight shoulder length hair, Knightwalker's also kinda spiker, etc, etc.
@Mars TerraI have my eyes on you, I know what you're capable of, bribing innocent girls to become magical girls and later become witches, or just so you can use them as experiments.
