Recently, seven huge caves suddenly appeared all over Japan. These caves are astonishing in scale, some are even bigger than buildings, and are bottomless, as if they go straight to the center of the earth.What is even more mysterious is that the entrances of some of the caves actually penetrated the clouds, revealing the blue sky.These sudden huge holes have brought great panic and chaos to the Japanese people.

The huge hole in the center of the city caught the citizens even more unprepared. The originally busy streets and buildings were swallowed up by these uninvited guests overnight.The government and relevant agencies quickly launched investigations, but so far they have not been able to reveal the true nature of these caves.Scientists have proposed various hypotheses, ranging from geological changes to the product of extraterrestrial civilizations, but none have been supported by conclusive evidence.

Faced with this series of unsolved mysteries, a trend of mysticism gradually emerged in society.Among them, a man named Ozawa began to attract people's attention.He claims to be a believer in “Cave God” and firmly believes that there is salvation% in the cave.Ozawa began to gather a group of believers who believed that by entering the cave, they could find hope for the future of mankind.

On December 1, a group of eight men and women, led by Ozawa, gathered at a resort.They followed Ozawa's rules. Everyone must tell why they want to enter the hole and record it before entering the hole.They hope that in this way, they can talk to each other and face the unknown journey together.

As night fell, the believers began to follow Ozawa's guidance and enter the cave one by one.Their future is full of uncertainty, but everyone has curiosity about the unknown and expectations for the future.What exactly is hidden in the depths of the cave?What challenges and opportunities will this group of believers face?
