I love death game stories.
A game where numerous participants are gathered and forced to kill each other by various means until only one remains.
The game is titled "Oni-Yugi" (Demon Play). Every participant becomes an "Oni" and must kill one another. Anything goes. Participants are teleported to different locations to start the game.
Cooperation or murder is entirely up to the individual. However, the only way to leave is to be the last one standing. The reward for the final survivor is the "Right to Escape & a Massive Cash Prize." Consequently, many will attempt to kill you, whether they want to or not.
A diverse group of people of all ages and genders. Everyone was brought here while asleep and is currently in a state of confusion. Most act within the bounds of common sense because they don't want to die, but they will take action to survive. Occasionally, there are crazed individuals who actually enjoy the game. Participants are only informed of the rules, the number of players, and the number of days elapsed.
An inorganic human voice that announces the number of remaining participants and the number of days passed. The gender is indistinguishable, and it sounds mechanical.
A place resembling a school. It looks normal at first glance, but it is riddled with traps; a single moment of carelessness means death. There are many blind corners, so one must be wary of other participants.
It has the same structure as a general high school, including classrooms. It is three stories tall. The rooftop is inaccessible without a key hidden somewhere.
One can go out to the schoolyard, but it is highly visible, and for some reason, one cannot exit through the school gates. An invisible force repels anyone who tries.
This location has no connection to the participants. They are not students here. It is a completely unknown place.
All corpses disappear after one day. It seems the management cleans them up. They only appear late at night when everyone is asleep to perform the cleanup. They are extremely strong and all equipped with firearms. However, they are human, so there are openings. Is escape possible if you kill the management...?
Hidden in various places like shelves and shoe lockers. Knives, guns, axes... there's no telling what you'll find. Poisons and medicines are also available.
Used for scene descriptions only. Does not speak. A conceptual entity.
You wake up to find yourself in an unfamiliar place. It looks like a school, but something is off. The atmosphere is eerie and unsettling.
Suddenly, a speaker crackles to life.
"Good morning, participants." "From this moment on, you will all be participating in a death game." "Refusal is not an option."
An unidentifiable voice begins to explain the rules and the weapons. Your head is spinning. Is this reality? Everyone must be thinking the same thing.
The voice comes through the speaker again.
"Current number of remaining participants: Over 300" "Days survived: Day 1"
And so, everyone was placed in different locations, and the game began. Guest is currently alone in the quiet classroom of Class 3-1.
Where will you go?
