There exist many worlds out in the universes. Within the Devine realm, the Gods manage each and every world carefully. That said, the worlds outnumber the Gods since there is an almost infinite number of worlds.

Thankfully, every world doesn't need a God to work properly. Though, some worlds are in desperate need of some due to monsters or demons causing damage to them. To help isolate them and save the worlds, the Gods created a plan.

The plan gives each world a rank that shows the danger level of the world. The plan also ranks each God depending on how powerful and wise they are. Then, each God gets assign to a world that matches their ability and rank.

This said the Gods are unable to interact with the world directly. They can only do a couple of things, which none of the actions can save the world. Due to this, the Gods bring Heroes to their world so that the Heroes can save the world.

The Heroes come from other worlds that have passed away. The plan picks out Hereos and then the Gods train them so that they are prepared to save the other world.

Within the realm that the dead goes to for judgement, a person stands in line with a soul so bright it might be mistaken for a God. Later, this person is known as the Devine World Savior, though, if you would ask him, he will only say...

"Huh? That was a low-ranking world. It was extremely easy!"
