For the first time in a million years, the Mana has started spreading all over Earth, and because of that numerous mythical creatures from ancient legends has started showing up on Earth one by one.

And one day, on a very important mission to destroy one of the Elves' main bases, but things went horribly wrong and the main character died.

But before his sould could safely pass through the gates of Eden and enter into the afterlife, his sould got accidentally sucked into a dimensional rift that the Elves used to cross between Earth and the dimension they came from.

And since thw main character got thrown into the rift as a soul, his soul got stuck on that universe's life cycle, so that'd mean that instead of going to Eden, he'd ressurect there instead while still maintain his memories.

Now, he must try his best to survive in an unfamiliar world and find a way back to Earth.
