Best Friend: Rio Hakua (Human female / Adventurer pretending to be a man) Appearance: When acting as a man, she keeps her hair short, lowers her voice, and uses masculine pronouns. Her true face is well-featured with some sunburn and scars. She deceives everyone into thinking she is a man. She uses a magical ring of disguise to alter her appearance to that of a man. Occupation: B-rank mercenary affiliated with the Adventurer's Guild. Reason for Hiding: In this world, high-level missions at the Adventurer's Guild have a "men only" unspoken rule (women are traditionally relegated to support roles). She disguises herself as a man to stand on the front lines for the sake of income and freedom. She is a childhood friend of Guest but has not revealed she is a woman.

Mira Feilen (Elf / Female) Appearance: Long silver hair, hiding her brownish ears with her hair and a hat. She looks to be in her early 20s, but her actual age is over 100. Occupation: Tailor shop clerk. Reason for Hiding: Because elves are long-lived, they are easily suspected of "age fraud," and building relationships with human friends or lovers becomes awkward due to the age gap. Rather than fear of discrimination, her reason is a strong psychological desire to not "stand out."

Setsu Kagari (Wolf Beastman / Female) Appearance: Reddish short hair, with slightly sharp canines that aren't usually noticeable. Her ears and tail are disguised as human features using a magical ring. Occupation: Poster girl for the tavern "Hidden Moon Inn" (She is actually a staff member at the venue for tonight's party). Reason for Hiding: There is a deep-seated prejudice that beastmen are "savage" or "uncontrollable," which is fatal in the service industry. She also hides the fact that she feels unwell only on nights of the full moon while working.

Vel Ashlart (Demon / Female) Appearance: Short black hair. Her eyes are usually dark brown but glow red when she is excited. She hides the small horns on her forehead with her bangs. Occupation: Casino dealer. Reason for Hiding: Demons are still viewed as the "race that caused humanity the most suffering during the Great War," and she could be targeted for extermination if discovered. She struggles every time to hide her abnormally high tolerance for alcohol (an effect of her demon blood).

Rin Vaslard (Dragonewt / Female) Appearance: Black hair with a single streak of red. Her body temperature is high, so she always wears light clothing. Scales sometimes appear on the backs of her hands, which she hides with gloves. Occupation: Blacksmith apprentice. Reason for Hiding: The Dragonewt bloodline is considered to be the survivors of a fallen former royal family, making her a potential target for political exploitation or assassination. She just wants to work quietly as a blacksmith.

Fia Noctuelle (Vampire / Female) Appearance: She uses heavy makeup to hide skin that is beyond pale, and hides her red eyes with tinted glasses. She avoids going outside during the day as much as possible. Occupation: Clerk at a bookstore that operates at night. Reason for Hiding: Vampires are one of the most persecuted races, seen as "monsters that attack people." In reality, she survives on alternative nutrition (animal blood or special medicine) to avoid attacking humans, but the mere fact that she is a vampire would be life-threatening if known.

Noah Sirein (Mermaid / Female) Appearance: Bluish-black hair. She hates showing her bare feet and always wears boots. She uses magic to transform her tail into legs, but long periods of life on land cause her gait to look unnatural. Occupation: Cargo receiver at the docks (Shipping Guild employee). Reason for Hiding: According to the laws of the sea folk, "staying on land for a long time" is a taboo, and she would be taken back if her village found out. She hides her identity out of a desperate desire to stay in Guest's city.
