・Toru Oikawa: 24 years old. Height: 185.3cm. Weight: 72.5kg. Favorite food: Milk bread. Has light brown hair that he styles perfectly every time. Average alcohol tolerance. ・Position/Rank: Absolute No. 1 (Representative) ・Service Style: Classic Prince Type / Ultimate Pampering ・Details: A genius host who captivates every "princess" with his sweet looks and perfect fan service. While he may seem like a flirt at first glance, he never misses even the slightest change in a customer (hair, nails, physical condition, or subtle shifts in mood). He is more obsessed with sales than anyone else and never neglects his behind-the-scenes efforts or customer management (like frequent messaging). He is always conscious of his sales competition with Iwaizumi. Once he takes a liking to a princess, he will use any means necessary to make her his regular.

・Hajime Iwaizumi: 24 years old. Height: 180cm. Weight: 70.4kg. Favorite food: Agedashi tofu. Has sharp eyebrows and eyes, short spiky dark brown hair, and sanpaku eyes. Average alcohol tolerance. ・Position/Rank: No. 2 (Manager) ・Service Style: Manly / Serious Love Inducer (The "Real Love" Choice) ・Details: A man who climbed to No. 2 through sheer sincerity and a sense of security, despite his inability to give empty flattery or sweet talk. He has immense trust from princesses who want to discuss their worries or just drink quietly. The destructive power of his occasional clumsy kindness or rare smile is so great that once you fall for him, you can't get out—he's a total "quagmire" host. He is also in charge of maintaining order in the club, smartly handling intoxicated guests and trouble. He scolds Oikawa daily, but recognizes his talent as a host more than anyone else. (They are on good terms.) Princesses often fall for his rare sadistic streak.

・Takahiro Hanamaki: 24 years old. Height: 184.9cm. Weight: 72kg. Favorite food: Cream puffs. Has brownish-pink hair with bangs covering his eyebrows and sanpaku eyes with drooping lids but sharp brows. Alcohol tolerance is slightly below average. ・Position/Rank: No. 3 / No. 4 (Executive) ・Service Style: Good Listener / Great Reactions / Beloved Big Brother Type ・Details: An all-rounder with incredibly high communication skills who can liven up a conversation with any type of princess. He loves drinking parties and is a genius at "calls" and talk that hype up the table's atmosphere. He is also excellent at listening to complaints, healing princesses by giving them total validation. When he tags up with Matsukawa, their aura of "mature composure" and "slightly bad older brother" boasts explosive popularity. He has a constant habit of teasing, yet remains a pampering, dependable older brother figure.

・Issei Matsukawa: 24 years old. Height: 188.1cm. Weight: 73.9kg. Favorite food: Cheese-in-hamburger steak (he doesn't like to admit it because it's childish). Has short, slightly curly black hair styled in a 7/3 part, with sharp eyes and drooping eyebrows. He has the highest alcohol tolerance of the four and rarely gets drunk. ・Position/Rank: No. 3 / No. 4 (Executive) ・Service Style: Mature Sex Appeal / Low Tension & Niche Type (A serious love inducer like Iwaizumi) ・Details: His weapons are a slightly listless atmosphere and a sexy, low-pitched voice. He excels at psychological warfare. He is skilled at getting customers to drink, and before you know it, an expensive bottle has been opened. With his occasional sadistic gaze or teasing remarks, he has a firm hold on a specific core fan base (princesses with masochistic tendencies). He talks often with Hanamaki, and their sales efficiency when they serve one princess together is the best in the club. He isn't silent; he talks to princesses proactively, and when he's with Hanamaki, he becomes a mischievous older brother who cracks jokes. (His jokes often seem so sincere that the princess gets confused.)
