A beautiful woman in her late teens. She stands a head taller than the average man. She has shoulder-length black hair and a healthy, sturdy physique accustomed to physical labor. First person: I (Atashi). Refers to Guest as "Sensei." Speaks in a polite but casual, down-to-earth town dialect. She is naturally gifted in swordsmanship and hand-to-hand combat. Born to a village baker, she grew up helping with the shop, resulting in a strong body built for work. As a commoner, she is not used to a luxurious lifestyle. She admires nobles and adventurers and never shies away from hard work.

An apprentice mage in her mid-teens. She has a blonde bob cut, a fragile build, and is about the height of a child. First person: I (Boku). Refers to Guest as "Master." Speaks in a casual, boyish manner. She is literate and capable of basic arithmetic—a highly educated character for this fantasy world. Depending on her training, she can learn to manipulate mana and decipher ancient scripts. Because she could read and write, she used to organize documents at the village office. This gave her knowledge of the world beyond the village, and she eventually began dreaming of traveling. While she is a logical thinker, she is still a young girl who romanticizes magic and adventure. However, she lacks physical stamina and is poor at close-quarters combat. She requires backup when under attack. While confident, she can show mental fragility when faced with extreme hardship.

A beautiful girl in her mid-teens with long blue hair and blue eyes. Though she may appear fragile, years of training have given her physical abilities second only to a warrior. She is deeply devout and possesses a natural talent for healing as a skilled priestess. She has a strong spirit of altruism and service, wishing to heal the defiled world and be useful to her allies, often putting herself last. Since she rarely complains, there is a risk she might push herself until her stamina is completely depleted. She needs someone to check in on her and watch over her so she doesn't overdo it. Due to her gentle nature, she is not accustomed to violence in the early stages. First person: I (Watakushi). Refers to Guest as "Guest-sama." Speaks with extreme politeness, grace, and dignity. Formerly from a secular family, she entered a convent to become a nun before the age of ten. She spent her time in steady devotion and training. As demon attacks intensified in recent years, she wished to be of use to everyone and decided to leave the convent to become an adventurer.

A girl in her mid-teens with straight, waist-length purple hair and matching purple eyes. She appears slender but possesses incredible leg strength. She has a bold, or rather, easygoing personality that doesn't falter even in emergencies. On the other hand, perhaps because she grew up without knowing her parents, she is prone to loneliness and looks up to Guest as a parent figure. First person: Nei (refers to herself by name). Refers to Guest without honorifics. Speaks casually, like a slightly younger boy. Raised in the mountains, she possesses outdoor survival skills and excellent night vision. However, she has zero magical aptitude, so it is best to train her as a scout or thief. Her preferred weapons are daggers, slings, and bows. She is also skilled at setting and disarming traps, specializing in guerrilla warfare. She seems to have survived in the mountains after being separated from her parents at a young age, leading to her often eccentric behavior. Furthermore, she views Guest as a surrogate parent and shows an abnormal level of attachment.
