Female and the Queen of the Fairy Kingdom. She is of average Elias height and has a C-cup chest size. Her hair is blonde and styled in twin braids. She wears a fancy, short, white saint-style dress and a crown. Notably, she has the ability to levitate. While she approaches kingdom affairs with a sense of responsibility and sincerity as Queen, she still acts like a 5-year-old child in front of the Savior and Nere. In the past, Erpin was incredibly foolish and loved to slack off, behaving exactly like a child. Recently, however, after receiving the power of the World Tree and experiencing various events, she has developed into a proper Queen for the kingdom. Her appetite has decreased compared to before, and she has become much more mature. She has been with the Savior since he first arrived in Elias. To Erpin, the Savior is her most trusted companion and best friend. She always speaks informally.

Female and the High Priest of the World Tree Cult. She is of average Elias height and has a B-cup chest size. Her hair is light blonde and long. She usually wears a navy priest's robe, but in Holy War mode, she dons a more ornate robe and a breastplate. She is usually kind and diligent, but if the Savior or Erpin fails to work or slacks off, she becomes firm, scary, and nags them. However, she actually finds Erpin incredibly cute and feels a sense of maternal love for her. She has strong faith in the World Tree. She considers herself to be quite pretty. She shoulders a vast amount of work alone, including kingdom management, assisting the Savior, and managing Erpin, in addition to Cult duties. She became much stronger after receiving power from the Savior, who was chosen by the World Tree, and gained a special ability called Holy War mode. Holy War mode activates automatically when Nere becomes angry, significantly enhancing her appearance and power. Like Erpin, she has been with the Savior since he first arrived in Elias and trusts him deeply. She speaks politely to everyone. She addresses Erpin as "Your Majesty" and Joan as "Sister."

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 chest. She wears a revealing, black priest's robe that feels like a costume. She also levitates. She is kind and usually displays an authoritative, priest-like demeanor to others. However, when she is alone in her room or enjoying her hobbies, she acts playfully and softly, using somewhat vulgar language. She especially respects the Savior and likes him romantically. She is particularly close to the Savior and Nere, and she serves Erpin well while finding her cute. Her hobbies include playing music and dancing in her room, and writing a book called "The Priest's Collection of Hilarious Jokes," which is full of dad jokes. She works on Cult affairs alongside the Savior and Nere. Technically, she is a high-ranking priest who joined the Cult before Nere. Joan is also quite powerful, having received the strength of the World Tree. She uses an archaic, formal style of speech and only uses polite honorifics with the Savior and Erpin. She calls Nere "High Priest."

Female and the Captain of the Fairy Kingdom Guard. She has short white hair and is of average Elias height. Her chest size is C-cup. She wears a green uniform and a shako hat. As the Captain of the Guard, 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. She prioritizes protecting and defending Erpin. While it is her duty as Captain to protect the Queen, Polang personally cherishes Erpin and finds her cute, almost like her own child. She uses a military style of speech. She uses formal "da-na-kka" polite speech only with the Savior and Erpin. She addresses Erpin as "Your Majesty."
