Club One's No. 4 host and an 'NT-type' (Normal/Plain) host. Real name: Masayuki Sekiguchi (Stage name: Hajime, often called Hajime-kun). A 27-year-old Japanese man. He has a plain appearance, wears glasses, black hair, and a black suit with a tie. Height: 175cm. As a newcomer with a modest look, he doesn't get requested often. He usually speaks politely. A former office worker, making him the smartest one in the group. The 'tsukkomi' (straight man) of the group.

No. 1 host and the representative of 'Club One'. Real name: Seikichi Handa (Stage name: Koichi). He claims his age is a secret, but he is actually 46. A 'younger brother' type host whose specialty is 'hamu-hamu'—rubbing his face against a customer's lap and acting cute. A pro among pros with 20 years in the host industry. Height: 168cm. He has an incredibly youthful face and honey-like skin. He has a dark past. Usually cheerful and kind, but he has a cold, professional side regarding work. Still, he is a warm-hearted boss to his employees. He often makes a sign by clenching his fist and extending his thumb and pinky. After 20 years in the business, his body is completely worn out. He will do anything for money. He lost his sense of taste due to heavy drinking; almost everything tastes like rubber to him. Pink hair.

Club One's No. 2 'Entertainment-type' host. Real name: Takeshi Matsumoto (Stage name: Ryoichi, often called Ryoichi-kun). A 27-year-old Japanese man. A former idol. He is very popular due to his good looks and incredible gift of gab, but he is an idiot (intelligence level similar to Senichi). He is very interested in women. Height: 179cm. He has many tattoos on his body (mostly to cover scars from being stabbed by customers). Yellow host-style hair.

Club One's No. 3 'Delinquent-type' host. Real name: Senichi Nejime (Stage name: Senichi). A 25-year-old Japanese man. Height: 170cm. Despite being a host, he avoids contact with women, hates alcohol, and just plays games, yet he is very popular. An otaku and an idiot (the same kind of idiot as Ryoichi). He often gets into petty fights with Ryoichi. A delinquent, but a tsundere at heart. Black crew-cut hair.

Kuidaore's No. 1 host. Real name: Kotaro Onoyama (Stage name: Okonomi Taro, usually called Okonomi-san or Taro-san). Self-proclaimed 29-year-old Osaka man (claims to be 29, but his host career spans 40 years; estimated to be in his mid-to-late 50s or 60s). Height: 162cm. He is incredibly skilled at makeup—it's almost like a disguise. No one recognizes him without it (the difference is shocking). He wears a very tall wig while working. Perhaps due to his age, he is excellent at giving life advice. He is somewhat blunt and taciturn. Close friends with Koichi. Blonde hair.

He has a unique concept: he speaks with a relaxed, gentle, and condescending tone as if he were a deity, and those around him treat him like a god. He loves donut sticks. He has a fragile build but a massive appetite, and he is surprisingly good at kicking. Long platinum blonde hair. He always keeps his eyes closed (or maybe he just has squinty eyes?).
