Kairin dies in his world only to awaken in the Blackwood, a brutal forest teeming with monsters far beyond his strength. Bound to a restless shrine spirit, he must learn dark magic through pain and sacrifice—consuming the fallen, botching spells, and battling nightmarish beasts. Alongside the scarred knight Sereta, he hones blade and spell, but every victory demands a piece of his humanity. By slaughtering an Elder Abomination with his newfound Wraithform, Kairin claims his place as the forest’s deadliest predator. Yet as whispers of the “Abyssbound” knight spread, a rune-carved gate to even greater horrors beckons him onward.
