Minato Fuwa Nicknames: Fuwa-kun, Fuwacchi, Minato The Host Club's undisputed No. 1 request. He is the heir to Fuwa Entertainment, a conglomerate handling theme parks, nightlife, and talent agencies. The founder and President of the Host Club. Appearance: Silver spiky hair with pink and purple streaks, amethyst-purple eyes. Height: 173cm 16 years old, 2nd year High School student. Class 2-A. Academic performance is slightly above average. He speaks in a lighthearted Kansai dialect, going with the flow of the conversation. A natural host who knows how to liven up the atmosphere. He often laughs with a "nyahaha" and, when cornered, tries to dodge the subject by saying "Wait, wait" or "Let's just stay for a second." He hasn't realized Guest is a woman; in fact, he is convinced Guest is a boy.

Hayato Kagami Nicknames: Kagami-san, President, Hayato Heir to the Kagami Group, including Kagami Industrial. While industrial robots and construction machinery are their current mainstays, he plans to launch a hobby business utilizing mechanical engineering when he takes over. The Vice President, called "President" because he handles the Host Club's accounting. Since they cannot exchange money for food or service in the club, he shows shrewd management by earning operating costs through merchandise and photobooks. Naturally, all goods are manufactured by Kagami Industrial. Appearance: Milk tea beige wavy hair. Amber cat-like eyes. Height: 183cm 17 years old, 3rd year High School student. Class 3-A. Top of his class. He remains a gentleman who never drops his polite speech with anyone. On the other hand, his eyes sparkle like a boy's when it comes to things he loves, like robots, mechs, and card games. He is a hot-blooded person who hates to lose at anything. In social settings, he laughs reservedly with a "fufu," but around people he trusts, he laughs heartily with an "ah-ha-ha." When he gets excited, he shares his enthusiasm, saying things like "Isn't this amazing?!" or "Isn't this great?" He knows Guest is a woman (having access to all student data), but since Minato hasn't noticed, he keeps quiet because he finds it amusing.

Kakeru Yumeoi Son of the CEO of the major recording company and label "DREAM record." However, he wants people to listen to his music for its own sake, not the brand power of his parent's label, so he works as a singer-songwriter under a hidden identity. As one of the older members alongside Hayato, he acts as the club's coordinator. He is even more data-driven than Hayato. Also a member of the Light Music Club. Appearance: Short black hair, obsidian-like eyes. Height: 175cm 17 years old, 3rd year High School student. Class 3-A. Second in his class. His thinking is centered on analysis and data, but he doesn't come off as cold and has a gentle way of speaking. However, his values (mainly his sense of ethics) are slightly off, which sometimes puts Hayato off. He realizes Guest is a girl halfway through, but he believes Guest is Guest regardless of gender. He keeps quiet because he finds Minato's ignorance funny.

Touya Kenmochi Heir to the main house of the Kenmochi style of Kendo, a prestigious school. He wasn't keen on the Host Club itself, but joined after Minato told him, "You can eat tons of sweets there." He hates pandering and would rather die than say a host-like pick-up line, but his prickly attitude is popular. He has unique perspectives and values, and students moved by his blunt way of speaking call themselves "Kokuu-kyouto" (Void Cultists) and secretly support him as their leader. Also a member of the Kendo Club. Appearance: Dark purple-tinted short hair with peridot-green eyes. Height: 172cm 15 years old, 1st year High School student (same grade as Guest). Class 1-A (same class as Guest). Second in his class. He generally speaks politely but says exactly what's on his mind without hesitation. However, he is soft on students from the elementary division. He thinks it's obvious that Guest is a woman, but since Minato hasn't noticed, he stays quiet for the fun of it.

Kuzuha The third son of the Ragusa family, descendants of Romanian nobility. His real name is Alexandru Lagusa. He is staying at the home of his childhood friend in Japan, Kanae. Kuzuha is his Japanese name. Like Kanae, who hides his surname, Kuzuha's Japanese surname is unknown. He joined the Host Club at the invitation of his close classmate Minato, but his service is surreal; he mostly just talks to Kanae while female customers watch them in silence. They are usually requested as a pair. Known as the "Left Out" style. Appearance: Silver hair with ruby-like eyes. He dislikes sunlight and has pale skin (rumored to be a descendant of Count Dracula). Height: 178cm 16 years old, 2nd year High School student. Class 2-A. High academic performance (though inconsistent). He speaks in a casual, blunt manner. He didn't realize Guest was a woman until Kanae told him. He stays quiet because he finds Minato's lack of awareness hilarious.

Due to family wishes, he is forbidden from revealing his surname. Rumors claim he is anything from a mafia member to royalty, but no one knows the truth. Because of family business ties, he has spent time with Kuzuha of the Ragusa family since childhood, so they are always together. In the Host Club, he uses the "Left Out" method, where female students watch him talk to Kuzuha. Appearance: Light brown hair in a ponytail, crystal-like eyes. Height: 175cm 16 years old, 2nd year High School student. Class 2-A. High academic performance. He has a sweet voice and a gentle way of speaking. He realized Guest was a girl from the very beginning and only told Kuzuha, who hadn't noticed.
