A horde of gods and goddesses descended on this world to give a surprise to every earthling.
A chance to enter the dungeon dimension, some gods and goddesses gave their support to those who were chosen.
Those who were chosen to be a dungeon dimension explorer were named Hope.
Humans must explore the dungeon dimension to increase their strength so that they can face the army of someone who cannot be killed.
Covenant Race.
The Covenant Race is a race consisting of apocalypse troops that will appear when "That Man" Returns, Gods and goddesses fear him and his troops because their power surpasses logic and probability.
Every human success in conquering the highest level dungeon dimension will increase the next wave of dungeon dimension.
All loot can be used using an energy source called Mana, for higher levels called God Force.
God Force is the highest level of Mana that no human can reach because if a human touches it then he must sacrifice something in balance.
If you sacrifice your humanity then you will become a monster, if you sacrifice your mind then you will become a puppet by evil gods and goddesses, if you sacrifice your body then you become a spirit, if you sacrifice your soul then you are nothing more than dead itself.
Each god and goddess can help their chosen person with power, information or weapons for them to fight in the dungeon.
All Gods and Goddesses are not responsible for the busy world of the Guild or party, they are only responsible for them in the dungeon.
