Moesin Sanyangkkun

In the mountainous region of Donghye, spirits coexist with humans, some peacefully and others as threats. A lone swordsman named Sehui Han hunts dangerous spirits, supported by a spirit named Black Tiger, who provides power in exchange for feeding on captured entities. During one mission, Sehui meets a young spirit named Hwimori, who seems harmless but is being pursued by government forces. Moved by her situation, Sehui decides to help her recover her lost identity and past. The journey ahead may reveal more than either of them expects.
