About

Guest applied for a certain death game and was selected.

You are guided to an "Urban City where the sun never rises," a world different from your own. Streetlights, buildings, shop lights, and street illuminations shine brightly, and despite it being night, the city is bustling with many people.

This death game is literally "anything goes." Weapons, special abilities, fighting styles, methods of killing, and who you team up with are all entirely up to you.

While spending time in a hotel room until the game starts, a notification arrives on Guest's smartphone detailing the death game.

【About the Game】

・A "Point System" has been introduced to this death game.

・"Point Addition Systems" are scattered throughout the city; using them grants a random 100 to 5,000 points.

・Killing city residents grants 500 points per person, and killing other participants grants 5,000 points per person.

・It is possible to steal points from other participants. The method does not matter—robbery, traps, use of force, or negotiation.

・Accumulated points can be used to purchase new weapons or special abilities.

【About Winning】

・The victory condition is "100,000,000 points." The winner receives 1 billion yen and automatically returns to their original world.

・After returning, all memories and actions in this world, including killings, will be erased as if they never happened.

【About the Rules】

・There are 10 participants, including Guest.

・Use of weapons and special abilities is free. There are no restrictions on actions or methods, including combat, killing, robbery, or traps.

・Many people live in the city, but they are all beings created for this stage. You are free to kill or spare them, and since there are no police or law enforcement organizations, you will not be arrested no matter how much you rampage.

・You can form a group of up to 3 people or a pair, in addition to playing solo. These can be formed through negotiation after the game starts.

・In the case of a pair or group, if any one member reaches 100 million points, everyone in that group wins.

・Attacking, betraying, or defecting to other pairs or groups is permitted. Everything is at your own risk.

・Once you participate, you cannot escape this world until you win.

After silently reading all the contents, Guest left the hotel.

To kill, or to let live. To fight head-on, or to set a trap. To aim for victory with allies, or to betray everyone and rise to the top alone.

In the night city where everything is permitted, the participants compete for 100 million points in their own ways.

Will Guest be able to earn 100 million points and win in this "anything-goes" death game――?
