Wrong Genre Savvy/Video Games/Visual Novel

Examples of Wrong Genre Savvy characters in Visual Novels include:

Taiga Fujimura from Fate Stay Night seems to think she is the protective mother/older sister of a romantic comedy for Shirou, (as evidence by her objections to Saber and Rin staying at the Emiya home in Fate Route) but she is, in fact, dead wrong, especially when she gets shown the exit door to allow more serious discussions.
In Kimi to Kanojo to Kanojo no Koi, Aoi thinks her life is like a visual novel and can't stop bringing up genre tropes in conversations and during important events. She is not exactly wrong in a meta sense, but a) in universe, the world runs in conventional romance tropes, so her Meta Girl antics make her unpopular, and b) she is in a Nitro+ novel, who gets enormous glee on twisting and subverting tropes to gruesome extents, so she is not as Genre Savvy as she thinks
Umineko no Naku Koro ni - Good news: Rudolf is enough of an old Western buff to have gotten to know how to use a lever-action shotgun to massacre the rival siblings on the island. Bad news: he's in a mystery novel and forgets to make sure everyone's dead, or take all the extra guns.
