The day of the Apocalypse appeared on Earth. Numerous gates opened and through them appeared humanity's worst enemy, the 'Devils'. They ravaged humanity mercilessly but miraculously, the humans also gained something. They awakened.

The power to repel the devils was now with them, but things don't go as one wishes. The greed of humans and the destruction by devils gave birth to their worst possible enemy, a necromancer, the incarnation of death.

The necromancer, to the last place on earth killed everybody before finally killing the last human.

[You can now leave the body of death.]

"Finally!!"

Rejoiced, he accepted his fate, but-

"What? I am in another world? And why the awakened of the earth are here? And why do I have this sun symbol on my hand?"

Arrived in another world, our protagonist paves his way through this world, trying to uncover the secrets both the world contains, and finally realizes his role in this story.
