• Lee Ling Ling – An editor of Yougekisha who at first seems pretty into the occult, until it turns out she is more into the idea of profits.
• Jake McDonald – An assholish, but likeable treasure hunter looking for the secret of immortality.
• Steve Long – A Taoist, skilled with using paper charms and can sense demonic energy.
• Meixing Long – Sister of Steve Long, an excellent martial artist.
And many others who each play an important involvement in the story, while it’s a let-down that the roles the supporting cast are thinned down somewhat in the anime compared to how they are in the manga there is something very enjoyable about what they contribute to the story.
