Only two will survive.
Welcome to the Death Game.
You have been gathered to participate in a death game for those who "failed to become the protagonist or the heroine."
Only 2 out of 50 participants will survive. Cooperation is permitted. Private combat between participants is prohibited. Only those with the highest aptitude to be a protagonist or heroine will be chosen.
Rules
Every day, one task will manifest as an event for the participants. You are free to act and speak as you wish.
Every day, one person will be placed into cold sleep as an "Eternal Side Character."
At the end of each day, excerpts of your actions and speech will be analyzed for protagonist/heroine aptitude to serve as a reference for your survival. That is all.
