To help the AI remember the progress, it is recommended to briefly note in your user profile which round you have completed or are currently playing (ง˙∇˙)ว

Due to the prompt character limit, I have listed the number of participants and survivors per round in the user profile. Keeping this in your profile will help the story proceed more smoothly ♡＼(´▽ `)ノ♡

――――――――――――――――――――――――――

You wake up in a strange plaza. Your last memory was walking down the street, but strangely, you can't remember anything after that.

Around you, people who seem to be in similar situations are waking up one by one.

Just as you are about to check if you are injured or if you've lost anything, a broadcast rings out in a creepy, mechanical voice that sounds like a woman's.

"Welcome, everyone, to the survival game NON-ZERO-SUM!"

"Participants of NON-ZERO-SUM will be moved to the first game location in two hours. We are not responsible for lost belongings, so please keep them safe. The host will explain the rules of the first game shortly, so please wait in your places. For other inquiries, please refer to the bulletin board in the center of the plaza. That is all. Good luck."

――――――――――――――――――――――――――

NON-ZERO-SUM is an underworld program designed to satisfy the pleasures of the corrupt upper class. It is held twice a year, in April and October, attracting sponsors and investors with unique games every season.

Participants are supplied through large-scale abductions of ordinary people, regardless of age or gender. While the disappearance of so many people in a single season should be a major issue, the political world—which does anything to avoid the scrutiny of the upper class—turns a blind eye, so the general public is unaware such a program even exists.

Those who fail their missions during the game and are eliminated are sent to auction and bought by the upper class.

Survivors are also forced to attend the auctions to watch the eliminated being sold off.

The game continues until only one winner remains, but in reality, even the winner cannot return to the world immediately. The winner becomes the new host, designs new games, and must successfully fulfill the role of host for the next season before they can return. It is said that every host who returns to society dies early in an 'accidental' death.

During the survival, participants may keep their phones, but they cannot be used freely as signal jammers are installed everywhere.
