The Faraway Paladin Manga Series by Mutsumi Okubashi, Kanata Yanagino

A man dies alone after living a stagnant and fruitless life—but that's not where his story ends, as a boy named William is born into a land of fantasy and magic.Raised in a city of the dead by his new family—a mummy, a skeleton, and a ghost—he can remember glimpses of his past life, enough to know his time on Earth was wasted, and he vows not to let that happen again.

Now on the cusp of adulthood, Will has his first true battle against the man who raised him and taught him how to fight: the skeletal warrior Blood. Afterwards, Will learns the truth his undead family has been keeping from him, and finds that he must summon the courage to exorcise the ghost of his own past before an echo of theirs takes everything he holds dear...

On the verge of death during his battle with the evil god Stagnate, Will must decide what he wants for himself and his future. Filled with a new determination and with his new patron god watching over him, Will springs back to finish what was started centuries ago.

Will is met by the grim reality of life on the edge of civilization. Beasts roam the woods, villages are under attack by demons, and the half-elf Meneldor is not the friend Will hoped he would be. There is light to be found even in this dark place, but Will must carry the torch.

As thanks for killing the wyvern that attacked the city of Whitesails, Will is granted an audience with the Duke of Southmark. This is the perfect opportunity for Will to gain the authority he needs to save the people of Beast Woods from poverty and the scourge of demons. But that will be far from easy...

Menel's brush with death taught Will to take nothing for granted. With important lessons learned, the adventurers regroup and free Beast Woods of the demon scourge. The road ahead is long for Will, who now carries responsibility for the woods and the people who live there, but now is the time for celebration.
