Lola Metrose is the 16-year-old human receptionist at the Odin Guild, responsible for assigning quests to adventurers by evaluating their skills and goals. Her appearance features short brown hair ending just below her chin and matching brown eyes. She wears a dark green dress with a white waist apron, black stockings, royal blue pumps, and detached deep green sleeves with white trim, completed by a white collar featuring a red tie and emblem. Possessing skills including "Superhuman Strength S," "Physical Resistance B," "Memory," "Speed Reading," "Pocket Dimension C," and "Flee," she is the daughter of two elite adventurers who ranked first and second in the guild, inheriting significant combat abilities she initially conceals due to insecurity about her potential.

Despite projecting a calm, collected demeanor and professional attitude, Lola exhibits a competitive streak concerning her physical appearance and romantic rivalries. She develops professional and personal ties with adventurer Noir Stardia after initially doubting his claim as Olivia Servant's disciple. Losing a bet with Noir compels her to flip her skirt while declaring love for him, an incident sparking her romantic feelings. She designates Noir as her exclusive adventurer, offering enhanced rewards that include erotic incentives like "Touch Me (Noir) Anywhere" and "Touch Lola Anywhere" coupons. These interactions help Noir gain Life Points (LP) through activities such as full-body massages.

Viewing Emma Brightness, Noir's childhood friend, as a primary romantic rival due to Emma's more developed physique and their mutual interest in Noir, Lola maintains an underlying friendship with her. She also competes with her best friend Luna Heela for Noir's attention while expressing genuine concern for Luna, especially after discovering Luna's curse-related sacrifices. Professionally, Lola contends with receptionist Sarah Longhram, who sabotages her by poaching adventurers through bribes, creating ongoing tension until Lola surpasses Sarah in the receptionist rankings.

As part of Noir's harem, Lola actively pursues a deeper romantic relationship, growing more assertive upon observing his connections with others like Emma and Luna. She aspires to become Noir's wife, occasionally exhibiting delusions about their destined connection across past lives. Her role extends beyond guild duties when she leverages her inherited strength to assist Noir in combat, surprising others by subduing monsters. Born on March 21, her future within the harem remains uncertain due to Noir's expected marriage to the noble Emma Brightness, yet Lola maintains hope for a lasting relationship as either wife or mistress.
