Sweet trap (the ones within x reader)

A series of strange disappearances have been occurring throughout Japan, and despite the police's efforts, no leads have been found apart from the fact that all of the victims were youths. (Y/N) (L/N), a sweet and caring teenage girl, is a popular uploader of "Let's Play" videos, one of her latest uploads consisting of an F2P game called "The Ones Within - Genome". Although online rumours claim that the game causes anyone who clears it to disappear, (Y/N) is wholly unaware until the rumours prove true -- she is summoned to a completely different world, and meets 9 teenagers like her. The 10 teenagers are welcomed into what is known as the 13th Avenue, headed over by a strange man with an alpaca mask calling himself "Paca", and are informed of their task: to work together in clearing stages of the game and retrieving the "chromosome", a keycard-like token of completion, to subsequently reach 100 million viewers in this livestream where death and injury can all occur.
