Summary: In an era where monsters threaten both humans and outlaws, ascetics arise to fight back over the past 500 years. Some of them were heroes, some of them were prophets, some of them were just ascetics going from place to place, in order to protect people from being devoured and the lands from being corrupted. Baek So-Juh is a girl isolated from her village by other youngsters, since she knows how to read and write. On a night in the bush of the outskirt, she witnesses monsters eating a corpse, just to encounter the next day a boy who happens to be an ascetic on the hunt for those same man eater monsters, calling himself Hong Kil-Dong. From then on, she decides to follow him in order to write the story of his life.
