Let me see if I get the story… So first of all, all these students are in like saw-ish scenerio where they need to fuck each other to get keys, which open doors and these doors lead to the exit so they can escape.
But, if any of them go against the rules they die…
Did I miss anything?

i watched all so i dont deserve a girlfriend i should die alone

If I am watching this, then I must be really fucking lonely.

4 minutes in. Nothing like violent murder via a painful electrocution to set the mood, eh?

The fuck am I watching

i just read the entire story plot of the game, end here is it for you if you want to know what actually happend for as far as i could understand the story (this is the true route, so the route wich you get if you play the game right i guess)
basically nemu is the good girl haha, she has to make the male protoganist hate her because then she and he would be set free. it is really hard to explain and i cant find the right words but basically kanae is the antagonis (so the bad guy) who wants nemu as depressed as possible for her plan to work.

in the end kanae dies and the male protoganist finds nemu who lost her memories and they live happily ever after :)

the hot teacher is an intelligence agent who lives.

the loli dies and the one with the black hair lives. (or the other way around, dont know their names haha)

hope it helped!

not too cool bt y’know moderate
