Former life insurance salesman Hajime Sekiguchi joins Club One, transitioning careers due to health issues. He leverages his polished sales techniques as a host, adopting an "NT-type" natural and comfortable communication style focused on genuine dialogue. Initially questioning his suitability for the unconventional profession, he overcomes reservations by applying his business acumen to attract clients and carve out a distinct presence. He commits to honesty and consistently kind, respectful treatment of all guests. Physically, he is 27 years old, stands 175 cm tall, and celebrates his birthday on October 10th (Libra). His blood type is B. A defining feature is his glasses, which typically obscure his eyes completely, rendering them invisible except in specific close-up shots. As the club's newest member, this promising rookie garners attention. His journey centers on navigating the host club's eccentric environment, learning from diverse colleagues, and growing within the profession by balancing his innate professionalism with its unconventional demands.
