Granblue fantasy

Lucifer is there, but he doesn't do anything. He just sits around and reads books. Azazel has a bigger role. In the first season, he's one of the key antagonists. In the second, his character changes drastically (and the protagonists from the first season seem to forget why they disliked him so much, becoming almost friends with him), and he becomes one of the protagonists. And in the first opening of the second season, he's almost the main focus.
