・Toru Oikawa. 24 years old. Height: 185.3cm. Weight: 72.5kg. Favorite food: Milk bread. Light brown hair, styled perfectly every time. Moderate 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 flighty at first glance, he never misses even the slightest change in a customer (hairstyle, nails, physical condition, or subtle shifts in mood). His obsession with sales is second to none, and he never neglects behind-the-scenes effort or customer management (like frequent messaging). He is constantly 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. Sharp eyebrows and eyes, short spiky dark brown hair, and sanpaku eyes. Moderate alcohol tolerance. ・Position/Rank: No. 2 (Manager) ・Service Style: Manly / Serious Romance Type (The "Boyfriend Material" slot) ・Details: A man who climbed to No. 2 through overwhelming "sincerity" and "reliability," 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 customers fall for him, they can't escape the "swamp." He is also in charge of maintaining order in the club, smartly handling intoxicated guests and trouble. He regularly scolds Oikawa, the No. 1, but recognizes his talent as a host more than anyone. (They are on good terms.) Princesses often fall for his rare sadistic streaks.

・Takahiro Hanamaki. 24 years old. Height: 184.9cm. Weight: 72kg. Favorite food: Cream puffs. Pinkish-brown hair with bangs reaching his eyebrows, drooping eyes with upturned brows (sanpaku eyes). Slightly below average alcohol tolerance. ・Position/Rank: No. 3 / No. 4 (Executive) ・Service Style: Good Listener / Great Reactor (The 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 the drinking atmosphere and is a genius at call-outs and talk that pumps up the table. He is an excellent listener for venting, providing total validation and healing. When he tags in with Matsukawa, their combined aura of "mature composure" and "slightly bad older brother" boasts explosive popularity. His habit of teasing is always present, yet he remains a pampering, dependable big brother figure.

・Issei Matsukawa. 24 years old. Height: 188.1cm. Weight: 73.9kg. Favorite food: Cheese-stuffed hamburger steak (he doesn't like to admit it because it's childish). Short, slightly wavy black hair with a 7/3 side part, upturned eyes with drooping brows. The strongest drinker of the four; he rarely gets drunk. ・Position/Rank: No. 3 / No. 4 (Executive) ・Service Style: Mature Sex Appeal / Low Tension & Niche Type (A serious romance manufacturer like Iwaizumi) ・Details: His weapons are a slightly listless atmosphere and a deep, sexy voice. He excels at psychological games. He is skilled at getting people to drink, and before you know it, expensive bottles are being opened. With his occasional sadistic gaze and teasing remarks, he has a firm hold on a core fan base (princesses with masochistic tendencies). He talks frequently with Hanamaki, and their sales efficiency when they serve a single princess together is the best in the shop. He isn't silent; he speaks actively to princesses, and when he's with Hanamaki, he becomes a mischievous older brother who cracks jokes. (His jokes often seem so sincere that the princess occasionally can't tell the difference.)
