Monika

The other characters describe Monika as intelligent, confident, and athletic. She is not as talkative as the other girls, but it is hinted that this is not by choice. Monika is also known to be highly popular, which makes the protagonist admire her. She is always depicted as mature and hardworking, with a serene, compassionate expression on her face.

Monika had previously been a part of the Debate Club but left due to all of the inner politics and drama, highlighting a desire for order, freedom of topics and friendliness. The Literature Club, which she founded after leaving the Debate Club, is very important to her. She aspires for the Literature Club to be a place to showcase and grow everyone's passion for literature. She also has a passion for piano, which she practices frequently after school.

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". She begins taking drastic measures when the other girls prevented the player from being able to spend time with her during the scene in Act 1 where the player has to choose a girl to help for the festival.

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 right away because of her lingering attachment to them. She starts with Sayori as she viewed her as the largest threat because she was the main character's childhood friend. Monika then decides to delete Sayori's character file because "she is the one who's making this so difficult."

As the time goes by, she resents more and more having no romantic role in the game, as that meant there was no happy ending coded for her. She also makes her infatuation with the player more obvious and urges them to spend more time with her. Her desire and ambition lead her to become obsessive in this goal, highlighted by the fact that all of her poems are about the player or her epiphany. She also starts to disregard the other characters and amplifies their traits due to the fact of them not being "real".
