About

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.
