(Single female protagonist + non-invincible + non-travel) Sunshine Mountain, a mysterious mountain bathed in golden halo. Because of the ore that can absorb sunlight, the weapons forged have become the nemesis of evil spirits, and this place has also become a place coveted by evil spirits.
Kawakaku Yuta grew up here and has a pair of eyes that can discern the subtleties of all things. He is an orphan who grew up eating hundreds of meals, and he is a family member with the villagers. He thought this mountain, this ordinary mining job, was his entire world.
Until that snowy night, the devil's claws tore everything into pieces.
Sunshine Mountain turned into a sea of fire. The eleven-year-old Yuta held a broken knife and faced the ghost's vampire technique alone. Every knife he swung was tearing his own bones.
The strongest pillar saved his life, but could not save his lost home.
"The blood debt of Sunshine Mountain must be repaid with the blood of ghosts."
Three months later, Yuta packed his baggage and embarked on the road to Mount Samagiri alone.
