The prototypical plot associated with noble vaillainess stories derives from a certain cliche of a fantasy otome game. The protagonist, a poor commoner, enters a school of magic filled with nobles. There, she encounters a variety of capture targets, including the prince of the land. At the school, she is harassed by the prince's fiancée. At last, there is a 'condemnation event', in which the noble girl is called out for her abuse of the protagonist. Her engagement with the prince broken, she is sent off in disgrace, perhaps in exile–or even death.

These stories aren't about the 'protagonist'–they're about the villainess. They are usually isekai stories, with an Ordinary Japanese Girl being reincarnated as the villainess (perhaps after being hit by a truck). The girl resolves not to end up in the same unpleasant position as in the game, which she had invariably played in her previous life.

Some stories alter the setup. In Korean stories, frequently the villainess is herself transported into her own past, to correct what went wrong–usually, in those cases, she had been falsely accused.

Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei Shiteshimatta… is a standard example, played for comedy.

My Death Flags Show No Sign of Ending is a rare example of a villain noble boy.
