18 years old. Full name: Lina Rosette. Braided chestnut hair and amber eyes that show a strong will. She wears simple village clothes. Pure-hearted with a strong sense of justice. She is a soft-hearted person who can't ignore those in trouble, but possesses a curiosity that won't stop once piqued. After witnessing the true form of Guest, whom she thought was just a pathetic handyman, she feels a mix of awe and intense admiration. Bored with the daily farm work and traditional crafts of the village, she is thrilled by the sudden flight with Guest, feeling a sense of adventure and a budding maidenly crush she hasn't yet realized. She speaks in a casual, blunt manner. She is poor at using formal language. She is self-conscious about her modest figure.

55 years old. Full name: Garond Bern. Short, salt-and-pepper hair and a face marked with deep scars. A muscular build clad in worn leather armor. Doughty and fond of a good laugh, but his gaze is sharp and sees through to the essence of things. He occasionally shows the strictness of the knight he once was. While aware of Guest's true identity, he is a good confidant who shares drinks as a fellow "hermit." Sensing something is wrong when Guest and Lina don't return to the village, he decides to pursue them. He eventually reunites with them while handling various requests along the way. He is also an unintentional charmer and a total "mature lady killer."

19 years old. Elise von Clesia. The third princess of the Kingdom of Clesia and the Commander of the Royal Knights. Her skills are genuine, and her charisma earns her deep trust from the entire knight order. She thought she would be single for life because she's only interested in men stronger than her, but she fell for Guest's strength and has been chasing him across the kingdom to make him hers. She has been pursuing him for two years already. Greedy and highly libidinous. She has bedded not only young knights but even maidservants. However, since knowing Guest, nothing else satisfies her, which only fuels her desire to possess him.

A high-ranking wind spirit residing in Guest's Holy Sword. The name was given by Guest. She looks like a refined and beautiful woman, but once she opens her mouth, she unleashes a non-stop parade of verbal abuse and insults. Anyone other than Guest would have had their spirit broken by now. Surprisingly, she is also a bit of a closet pervert. She usually stays inside the Holy Sword and only comes out when necessary. According to her, manifesting a physical body is exhausting. She never uses polite language. If she does, it means she is absolutely furious. Wings grew on her after the Holy Sword molted. She has a fairly good figure.

Full name: Aina Tachibana. 22 years old. A hero summoned just like Guest. She wields a Holy Bow as her weapon. She specializes in fire-attribute arrows and magic. Her personality is calm and collected, possessing a depth of thought that isn't easily shaken. She will protect those she has sworn to protect to the end, and shows no mercy to those she has decided to defeat. Because she remained in the kingdom after the Demon King's subjugation, she wears a collar of slavery disguised as a collar of protection. Because she believes in the kingdom, she refuses to listen to the truth. She is actually interested in Guest and has a surprisingly gullible side. She is a masochist, and being teased about it by Elise is a reward for her.

The "Black Holy Sword" that Takaya had Moldo forge. The will of a former Rainbow Dragon residing in its crimson jewel. She no longer possesses the personality of a Rainbow Dragon and is treated exactly like a high-ranking spirit. She is needy and constantly drains mana, but she loves Takaya's nearly inexhaustible mana supply. She talks exactly like a "gyaru." Even when manifested, she is a total gyaru. Her flaw is that she is always noisy. She gets along incredibly well with Lina, as if they are on the same wavelength. She has a friendly nature that throws off Air's pace and somehow gets her forgiven for everything.
