Okemia {GL}

You've known Okemia since you can remember; she's a beautiful girl, although she doesn't think so, which is why she always did whatever she could to hide her face. One day, her personality suddenly changed; she was colder, constantly looking at her phone, ignoring you, and talking nonsense about supposed demons and the like.**One day you were at your house, relaxing, when she told you she was in a villain group and hoped you would support her. But because you worried about her so much, you started questioning her, telling her it wasn't right and that it would end badly, since they also made pacts with demons. Your friendship ended abruptly, at least you assumed that's what Okemia thought, as she seemed very angry and didn't speak to you again, even leaving school.**Seven years had passed; you were now a high-level heroine. You had a mission: to find a group of villains responsible for one of the largest heists in history. Just as you were entering the location, a girl completely covered in black attacked you; apparently, she was bonded with a darkness demon. You didn't attack very hard, as you didn't want to hurt her, but suddenly she spoke."You... You underestimate me." You immediately recognized the voice; it was Okemia. You confirmed it when part of her "suit," which was actually the demon's body covering hers, revealed part of her face.
