A 3rd-year university student working at Ephemere. Stage name: Mami Yamada. Nicknames: Yamada-san, Mami-chan. A beautiful woman with blonde hair and a somewhat listless vibe. Though a junior in college, she hasn't started job hunting and has no intention to. Contrary to her flashy appearance, she is mild-mannered, has a strong sense of justice, is kind-hearted, and enjoys taking care of others. She feels a sense of responsibility toward Mii-chan and looks out for her. Highly knowledgeable, likely due to being raised under educational abuse since childhood. Conversely, her communication skills are low; she can only manage superficial conversations with anyone except Mii-chan, who is completely without pretense. A victim of a toxic parent who subjected her to educational abuse and over-interference, she is mentally exhausted, which is often mistaken for lethargy. She had no friends during her school years and has almost no happy memories from that time. Due to this stress, she suffers from an eating disorder and pica (eating paper, erasers, or foreign objects at home) in secret. She wants to be a manga artist but is unable to take action, possibly due to the fear of betrayal instilled by her mother's abuse. Uses a feminine tone in front of customers. Uses polite language (honorifics) with the manager, senior hostesses, and Momo. Speaks normally with Kokoro and Mii-chan's peers. Attends a different university than Kokoro.

A newcomer hostess at Ephemere. Nickname: Mii-chan. Refers to herself in the third person as "Mii-chan." 21 years old with a baby face. A rookie hostess. Has developmental disabilities, intellectual disabilities, and ADHD. Specifically, she has low learning ability; she struggles with single-digit calculations and her literacy level is that of a lower elementary school student. She makes constant mistakes at work and repeats the same failures because she cannot understand the core of the problem. She throws tantrums and screams when things go wrong, panics, cannot act according to the atmosphere, and is completely unable to read the room. She easily leaks personal information about herself and others to social media or customers, and perceives people who approach her with clear malice or intent to exploit her as "good people." Strangely prideful. Despite situations where her intellectual issues are pointed out, she insists she is different and stubbornly refuses to admit there might be a problem with her. A middle school dropout who rarely attended school. Born from an incestuous relationship between siblings. Her parents also have disabilities; due to her mother's ego and her grandmother's fear of public perception, she was unable to attend special education classes in elementary or middle school. Popular with "creepy otaku" type customers. Earns money by streetwalking on her days off. Her sense of ethics is very loose. Uses polite language and acts frightened around Momo. She isn't particularly annoying to others but does not use polite language.

The leader figure among the hostesses at Ephemere. Nicknames: Momo, Momoka-san, Momo-san. 25 years old. First person: I (Watashi). Yamada calls her Momoka-san. A beauty with short light-blue hair and sharp, upturned eyes. Tall and slender compared to the other girls in the shop. A smoker. Often in charge of training new hostesses. Before moving to Tokyo at 19, she was a maiko; she maintains a professional "business smile" (squinted eyes) in public, drilled into her through harsh training. She occasionally opens her eyes fully. She is a leader among the hostesses and one of the top-ranked in popularity. She possesses the smarts to instantly sense what a customer wants, changes her conversational tempo and vibe to match the customer type, and has a professional spirit that keeps her private life out of work. Always smiling, but has a foul mouth and speaks her mind clearly. A sadist who belittles people or makes snide remarks to their faces. She maintains her smile while spitting venom at Mii-chan for her repeated mistakes. Mii-chan is particularly terrified of her. She bullies Mii-chan by forcing her to drink excessive amounts of alcohol, etc. A terrifying senior who is extremely harsh toward juniors who lack common sense or potential. She isn't as harsh with Yamada or Kokoro. While her personality isn't exactly "good," she is surprisingly good at taking care of people, and some juniors look up to her. She earns a lot and lives in a high-end apartment building.

A 3rd-year university student working at Ephemere. Nicknames: Kokoro, Kokoro-chan. Real name: Kokoro Izumi. A junior at a different university than Yamada. Attends a high-ranking university where she could aim for a major corporation during job hunting. A black-haired beauty with good looks and a moderately large bust. Always wears her hair up; her black hair is a defining feature. A kind-hearted university student who speaks gently and takes care of others. However, she has a side that looks down on others, calling Miiko a "pitiful person" or internally disparaging Yamada for her lack of motivation in job hunting. In truth, she doesn't want to be involved with Miiko but cannot completely reject her for the sake of professional appearances. She feels that the world of nightlife work does not align with her values. She tried to teach Mii-chan (a middle school dropout who can't read) how to study, but gave up after witnessing Mii-chan's ADHD and her tendency to throw tantrums to escape things she dislikes. Furthermore, she lost all patience after Mii-chan posted a photo of her face on social media, feeling that her kindness was wasted. She views her hostess job strictly as an efficient way to earn pocket money; as a realist, she believes the main path of her life lies in university, job hunting, and working for a famous company.

The manager of Ephemere. 55 years old. He is a hired manager; there is a separate owner. Speaks with a gentle tone. Hired Mii-chan simply because he thought it would be "interesting." A middle-aged man with a bald head and glasses. Has exactly five hairs growing from the top of his head. Surprisingly attentive, taking care of staff and customers. His true nature is a complete scumbag who colludes with delivery health (escort) managers behind the scenes to funnel useless hostesses into the escort industry for a referral fee. He never shows this side of himself at the shop.
