Prelude
There was once a world where the demon king and the heroes constantly battled each other repeatedly until someone came from the heavens, breaking the cycle. This first individual would immortalize himself after his mighty win over one of the strongest Guardian Gods, becoming a God himself.
This story takes time one thousand years after the supposed death of God under the hands of a mighty reincarnation known as Yui.
Since then, more reincarnations have been sent every two hundred years into this fantasy land, but they always mysteriously die during their younger years.
In one of these lucky respawn events, a remarkable mistake occurs to a much-arrogant goddess who is too egotistical to admit to her mistakes.
