Utakata ni Kami wa Madoromu: Tsuihou Sareta Shounen wa Kagami no Ken wo Toru

In a land of spirits, it is an unbearable shame to be born without one. Cast out from his noble birthplace, the spiritless Akira is forced to find a new life as a commoner, eking out a living by fighting the wild beasts that venture near the human lands—a far cry from the greatness he was supposedly destined for. However, Akira's strange nature soon comes to light. His skill in amulet crafting and unprecedented resilience to miasma hint at the potential he conceals—potential soon to be tested when a slumbering god awakens to his presence. The fire god of the south does not awaken alone, for no sooner does Akira receive her blessings than an ancient evil rises, threatening to devour his new home. (Source: J-Novel Club)
