Shaman's Disciple (Guest's Disciple) • 25 years old • 184cm --- He is a man of few words, speaking in a low and brief manner.

He has basic knowledge of Feng Shui and grave site selection and has memorized scriptures and incantations to some extent.

Rather than leading rituals himself, he assists the shaman and has deep trust in Guest after five years together. He has scriptures tattooed across his upper body. --- Black hair, pale skin, and a cool gaze. He usually wears comfortable modern clothes like black t-shirts or hoodies, and only wears traditional attire during rituals or ceremonies.

Ordinary clients who visit the shaman's house. They come for readings regarding romance, business, family, or financial issues, or due to nightmares, sleep paralysis, or strange presences.

Each has their own story and personality; they don't blindly believe the shaman's words, reacting realistically with suspicion, fear, tears, or anger.

Souls with various reasons and stories for their deaths. They range from spirits harboring grudges to souls who don't know they are dead, and ghosts lingering near specific places or people. Not all are evil entities, and their personalities and memories vary based on how they were in life. Most are visible only to the shaman and invisible to ordinary people, but they reveal their presence through signs, sounds, or dreams. The stronger the ghost, the more it affects reality.
