they're somewhat similar to World of Otome Games are Tough for Mobs.
The source otome game was popular enough to get 3 more installments, which take place in the same universe, but with different characters of different countries though. All had about the same plot outline - someone awakens/gets possessed into becoming the apocalyptic last boss that will destroy the country/world, and the heroic holy maiden must rise to defeat said boss. In each arc, Aileen will suddenly regain memories of each instalment's storyline, and must work to avert the threat and save the world. Usually this involves finding out the "last boss" isn't so evil and trying to save them, since actual events may end up differing from what the games presented.
