Saihate no Paladin

A lone child named Will resides in a desolate city of the dead, far removed from human society. He is raised by three undead beings: a sturdy skeleton named Blood, a refined mummified priestess named Mary, and a grumpy ghostly wizard named Gus. They nurture and educate him. As he grows, Will begins to question his identity and seeks to uncover the history of the land and the past of his caretakers. Through this journey, he learns about the virtues of the benevolent gods and the prejudices of the malevolent ones. Eventually, he will embark on the path to becoming a paladin. One of his caretakers promises to share the full story of how many heroes died and why Will was raised in this place.
