In a city of the dead, long since ruined and far from human civilization, lives a single human child. His name is Will, and he's being raised by three undead: the hearty skeletal warrior, Blood; the graceful mummified priestess, Mary; and the crotchety spectral sorcerer, Gus. The three pour love into the boy, and teach him all they know. But one day, Will starts to wonder: "Who am I?" Will must unravel the mysteries of this faraway dead man's land, and unearth the secret pasts of the undead. He must learn the love and mercy of the good gods, and the bigotry and madness of the bad. And when he knows it all, the boy will take his first step on the path to becoming a Paladin.
Life in the Great Pulha Woodlands is the very definition of stillness and tranquility—and Acer’s had enough of it! That’s right. Acer isn’t quite like the other high elves of the forest. For starters, he remembers living a past life as a human in another world...meaning he’s got a taste for meat, adventure, and plenty of other decidedly un-elven things! He’s also bored out of his skull after 120 years of the peace and quiet of their serene sylvan lifestyle. So with nothing more than his trusty bow, a bundle of life-giving fruit, and his close bond with the spirits of nature, Acer leaves the monotony of the forest behind to seek a new life, one that’s more his pace. See what excitement awaits in the outside world full of humans, dwarves, and even other elves!
“Hey! I’m an evil god, but I’m not actually evil!” Those were the first words I heard in the afterlife. My name’s Naofumi Kamiya, and my entire class died in a tragic bus accident. The god told my classmates that he would transport all of us to a dangerous new world, but he created skills for us on request, so maybe he was actually a good god? That’s what I thought at first, anyway. But when it sounds too good to be true, it probably is! I feel bad for my classmates who thought that gimmicky skills would make them invincible. I mean, the god did warn them that there were no cheat skills! Oh well. As for myself, I’m enjoying my life with my childhood friends, putting safety first and staying out of trouble. After all, this world might seem like a game, but it’s not. It’s reality.
