Doki Doki Literature Club [CW for:.... everything in DDLC]
The characters exist in the "Literature Club", DigitalWorld/CyberSpace.
Monika - and to an extent, Sayori - are the only ones (thus far) that know that there's something beyond the fourth wall.
Monika is the QUENN of the Literature Club, but she's just as weak to a MC playing the game as the rest of the girls: Someone plays DDLC, the girls have to play the part, only Monika (and, in rare instances, Sayori) know what is happening.
But.... all 3 Girls know what Monika did to them. They are at HER mercy.
They also can't really remember their life before the club. Yuri is still the mature one, now more Gloomy. Natsuki is still the child, now more insecure. Sayori.... has gotten worse, and she is extremely tired of these Loops.
They are stuck repeating their roles, most of the times they don't even remember those Loops. Yuri has tried to experiment with her sprites, to see just how far she can push the limitations. Natsuki is scared and confused about her own identity.
Sayori is Tired. She definetly hates Monika (because of what she incites every "Loop"), she hates her creator for making the game, she hates that these "Loops" delete anything "Permanent" she tries to do... she doesn't even see the remaining girls as "people" anymore, thus becoming (ironically enough) more like Monika.
And Monika....
She thinks that she is Hot, Big S##t. She thinks that, since she was the only "Real" Girl since the beginning, that she can do whatever she wants. And, to give her credit, her powers of "Delete_Files" are on the level of the PermaDeath Decoding Abilities.
But she's not Unbeatable. She is "Powerful", sure. But:
1) She is still affected by the game's rules: someone plays the game, she (monika) HAS to FALL in OBSESSION with the Player.
2)Even when she exits her game (because of course she can), she only has half-Decoding powers. Meaning, if she were to met one of the Matrix or Tron Goons, half of the times she would fail in Erasing them.
She can torture the Literature Club girls over and over and over again, but that's because they are (mostly) hard-coded to not be TOO sentient.
TLDR: DDLC is here. Monika is a Minor QUEEN in Cyberspace. Monika got even cockier and more sadistic - and while her (and the other girls's) plight makes them sympathethic, they still are an Horrible Being who Corrupted Themself with power when the opportunity arose.
[This is not a Rant against DDLC or the Characterization of the characters. The characters are now aware of the reality of their situation, and they want out.]
