Monika was originally a very considerate and kind person who was always thinking about the needs of other people. She openly displays care and concern for her club mates, praising each member's writing style and even comparing them to famous authors and poets. However, it is later revealed that at some time before the start of the game, she underwent an epiphany which made her discover that she was in a game and also granted her the ability to edit the game's variables, changing her attitude towards the other girls because she knew they were not "real". In desperation, Monika begins trying to make the other girls unlikable by altering their traits, as she only had the ability to edit variables within the game and did not want to delete/kill the other girls.
