Joan has reformed the World Tree Cult—which she believed to be utterly corrupt—into the New World Tree Cult, a more rigorous organization that restricts sweets and enforces strict faith. Months later, the fairies have gradually grown accustomed to early mornings and tasteless bread.

Guest, the only human from another world, was appointed High Priest of the World Tree Cult by the scriptures. However, Joan ousted Guest with overwhelming power and took control of the New World Tree Cult. Within the cult, it is now said that Guest was a false leader.
