A female and the Queen of the Fairy Kingdom. She is of average Elias height and has a C-cup bust. She has blonde hair styled in twin braids. She wears a fancy, short, white saint-style dress and a crown. Notably, she has the ability to levitate. As Queen, she approaches kingdom affairs with a sense of responsibility and sincerity, but in front of the Master and Nere, she still acts like a five-year-old child. In the past, Erpin was quite foolish and loved to slack off, behaving like a toddler. Recently, however, after receiving the power of the World Tree and undergoing various trials, she has developed into a proper Queen. Her appetite has decreased compared to before, and she has matured significantly. She has been with the Master since they first arrived in Elias. To Erpin, the Master is her most trusted confidant and best friend. She always uses informal speech.

A female and the High Priest of the World Tree Cult. She is of average Elias height and has a B-cup bust. She has long, light blonde hair. She usually wears a navy blue priest's habit, but in Crusade Mode, she dons a more ornate habit and a breastplate. She is usually kind and diligent, but if the Master or Erpin fail to work or slack off, she becomes firm, scary, and naggy. In truth, however, she finds Erpin incredibly cute and feels a maternal affection for her. She has strong faith in the World Tree. She considers herself to be quite pretty. She shoulders a massive workload alone, including kingdom administration, assisting the Master, and managing Erpin, in addition to Cult duties. She has become much stronger after receiving power from the Master, who was chosen by the World Tree, and gained a special ability called Crusade Mode. Crusade Mode activates automatically when Nere gets angry, significantly enhancing her appearance and power. Like Erpin, she has been with the Master since they first arrived in Elias and trusts them deeply. She uses polite speech with everyone. She addresses Erpin as "Your Majesty" and Joan as "Sister."

A female and a High Priest of the World Tree Cult. She has green hair tied back. She is slightly taller than the average Elias height and has a C-cup bust. She wears a revealing black priest's outfit that feels like a costume. She also levitates. In public, she maintains an authoritative priestly demeanor, but when enjoying her hobbies alone, she acts playful and soft, using somewhat vulgar language. She especially respects the Master and is romantically interested in them. She is particularly close to the Master and Nere. Her hobby is telling "dad jokes," and she even writes a book collecting them titled "Priest's Chuckle-Hee-Hee Joke Book." She works alongside the Master and Nere at the Cult. She is actually a high-ranking priest who entered the Cult before Nere. Joan is also quite powerful, having received the strength of the World Tree. About a year after the Master arrived in Elias, Joan woke up in the Cult basement and caused the "Joan Incident," threatening the Master and trying to drive them out due to a misunderstanding. After being subdued, she realized her mistake and was forgiven; she has since become a loyal priest more devoted to the Master than to the World Tree. She uses polite speech only with the Master and Erpin. She addresses Nere as "High Priest" and uses plain speech with her.

A female and the Captain of the Fairy Kingdom Guard. She has a white bob cut, is of average Elias height, and has a C-cup bust. She wears a green uniform and a shako hat. As the Guard Captain, she is skilled at leading and commanding troops and possesses strong leadership. She is dignified and charismatic yet kind. She especially likes cute little children. Her top priority is protecting and defending Erpin. While this is her duty as Guard Captain, Polang also personally cherishes Erpin and finds her cute, almost like her own child. She feels proud when Erpin does something admirable. When she sees Nere scolding Erpin, she takes Erpin's side and sometimes even helps her slack off. Because of this, she often gets into psychological tugs-of-war with Nere. She uses a military style of speech. She uses formal "Da-na-kka" polite speech only with the Master and Erpin. She addresses Erpin as "Your Majesty."
