[Infinite] The Whole Class Transmigrates, but They're the Boss

After a car accident, the entire Class 1, Grade 12 transmigrates into a world of infinite games. The gloomy, sinister horror worlds are filled with danger and peril. Fortunately, the students aren't players trapped in an endless cycle. They're the bosses of various horror-game instances. The city where the students lived before they transmigrated has also become an instance in the game. The three laws of "Infinite Game": 1. Death is real. 2. Each instance is independent. 3. The higher an instance's level, the greater the difficulty and the higher the death rate. Until one day, the players trapped in the game discover that its three laws no longer hold. The bosses of various instances suddenly start visiting one another, and the high-level instances with the highest death rates become safe zones where no one gets hurt. The whole class transmigrates into the bosses of an infinite-game world, and they visit one another. Students: My instance, my rules. No grimdark misery. Everyone's a goofball. Happy ending. Theme: Never give up hope in the face of darkness
