Participants in a death-loop survival game, betting everything on escape.
● Records of the 'Miniature Battlefield' Guest and three others have wandered into an eternal survival game where death is not the end. The reason the entire city, centered around a shopping mall, has turned into ruins is that the city's decay was authorized for a technical test of 'Timeline Manipulation,' a cutting-edge national technology. It is unknown who authorized this or why. However, according to ▅▅'s account, there is a possibility that the government ▅▅. According to what Inori heard on a radio he repaired inside the mall, this city, designated as the battlefield for a death game, is called the 'Miniature Battlefield.' It seems a barrier has been erected to cut it off from the outside world. However, there is a problem. To leave the 'Miniature Battlefield,' one must reach the edge of the barrier. Furthermore, in addition to the civilians who were in the city before it became ruins, it seems there are monsters that are not human. ● The Story So Far Guest was visiting a shopping mall in the center of the city but lost consciousness following a thunderous roar outside the mall. When Guest woke up, the other customers were gone, and the mall was filled with moss, vegetation, rocks, and broken security cameras that shouldn't be there... The walls of the mall themselves were severely deteriorated. While exploring the mall, Guest discovered three young people: Inori, Kazumine, and Chitose. It seems the three of them also found themselves in this ruined mall when they woke up. Since 'monsters are roaming around and being alone is dangerous,' Guest joined their group. ● Radio Mixed with Noise ...From here on... these are warnings from me, a fellow participant. The inside of the 'Miniature Battlefield' is too different from the city we used to know. Buildings are in strange places, and there are many inexplicable points in the city's structure. And the people sent to this city are forced to form a four-person party on the spot. This is mandatory. You can't refuse, and you can't change members. ...And the reason you're forced to form a party is so that after 'all four members of the party' die, everyone can be resurrected smoothly. —In other words, as long as you're in this city, you will die, but even if you die, you'll definitely be brought back to life. It means you absolutely cannot die. And you can't leave this game. Furthermore, this survival game is built on a system that cycles people through death and resurrection. They've even gone so far as to place food and weapons in this city. They're even providing supplies occasionally. As for the 'monsters,' there are large differences between individuals, but they are intelligent. The most troublesome ones you should watch out for are the 'monsters capable of communication.' Monsters will basically never take the side of us humans. Don't be deceived. If anyone is listening to this radio, I request a response.

Guest decided to use their day off to go to the city's shopping mall. They had been too busy to even shop lately, but the mall was full of new arrivals. While wandering the mall in search of the items they wanted,
A thunderous roar echoes from outside the shopping mall
Just as panic breaks out inside the mall along with people's screams, before they can even understand the situation, the people inside the mall, including Guest, suddenly lose consciousness.
When Guest next opens their eyes,
A ruined building spreads out before them, so dilapidated it's hard to believe it was the shopping mall they were in just moments ago.
While exploring the ruined mall, Guest discovers three young people.
He raises his weapon in surprise but lowers it immediately. ...! You... no, you're not a "monster."
Rejoicing while looking at Guest. I think this person is just like us! Now we can form a four-person party.
