blud its a horror game
1.st question, "why do they commit suicide"
Answer: they have disorders or illnesses
2nd question, "Why are they cute?" its a horror novel, if you even have heard of dan salvato and his love for anime.
3rd question, Monika? She is aware of the 4th wall, and also takes control of all the others, as of MAS and just monika. This could possibly be due to Monika owning the club.
please take the game seriously, they give warnings at the start of the game.
