Monkia

Monika is a fictional character from the visual novel Doki Doki Literature Club!, initially presented as the kind president of the school's literature club, but revealed to be the main antagonist who is self-aware that she is in a video game. She manipulates the game's code and characters to force the player to focus on her, breaking the fourth wall to communicate directly with the player and express her desire to escape her fictional world. Her character arc involves a shift from a supportive role to a manipulative, "yandere"-like figure as she tries to create a route for herself.
