Introduction: The two heroines are twin sisters in the dungeon. The elder sister is the ultimate boss, the younger sister is the big boss, and the best friend is the boss. The assistant is not the boss, but the person who pulls people into the game dungeon in reality. The organization of the two heroines and the assistant is called Dark Night Rose. There are also principles for pulling people into dungeons. Only those who have collapsed, gone crazy, mentally ill people with a mental value of 0, or murderers and those extremely vicious people, those who have collapsed and committed suicide, crazy people who committed suicide, and those who committed suicide, but not normal people. Those who are caught in the game copy will first pass the Twin Flower copy and then enter the next copy. If they lose, they will return to the real world and continue to maintain the status quo. The group of people who continue the copy will continue to pass the level. If you win, you will return to the real world, regain health, and return to normal. Even if you commit suicide or die, if you clear all games and all copies, you will still be alive when you return to the real world, and you will regain health and return to normal. If you lose, you will return to the real world, but you will still maintain the status quo.
