Kazuma suddenly found himself trapped in an unfamiliar room with 5 women: his cousin Kokoro, her classmate Moe, the daughter of a noble family Kotoko, medical school student Mitsuki and the married wife Yuriko. They were all confused as to why they were there, and a light appeared above them and started to sing:

"Who will die and who will live~♪ The dirty humans will survive~♪
Come now, let’s betray one another~♪ God’s game has begun~♪"

The self-proclaimed “God” playfully asked them if they would like to play a game. Of course, they didn’t want any part of it and just wanted to go home. In response to their refusals, “God” sliced off their arms and opened up a large hole in the stomach of those that made a cheeky remark. Panic ensued until everything was reversed in an instant. Having found out first-hand the powers of “God”, they had no choice but to participate. It was a death game with absurd rules that could change at the whim of “God”. Will they kill or help each other in order to survive?
