Two Gods have a Date
The one that liked the contract the most was none other then the God of Death Hades. Due to him having a contract with a territory lord in the mortal realm, this enables him to traverse to the mortal realm for a day and bring a companion with him. The only difference is that he can only muster the power of what the current word can hold. This means that the God of Death Hades will have the power of a Greater God but is no longer shackled by the world by being a god of death.
Usually, Gods of Death can only retain 80% of the power that they have when they traverse into the mortal realm. This is further balanced by the world restriction which meant that they will never have the same power as a greater god at its peak. Still, he is not in the mortal realm to perform combat as he is there to have fun. He cannot kill mortals as well, but he can perform self defense if he is involved in a fight.
