Jaki is a Japanese author recognized as the original creator of the light novel series The Most Notorious Talker Runs the World's Greatest Clan, which has since expanded into a manga adaptation and an anime television series. Jaki began writing the story as a web novel, serializing it on the user-generated publishing site Shōsetsuka ni Narō from September 2019 to July 2020. The series was later acquired by the publisher Overlap, who began publishing it as a light novel under their Overlap Bunko imprint in June 2020, with illustrations provided by the artist fame. To date, four volumes of the light novel have been released.

The property has seen significant adaptation across media. A manga adaptation, illustrated by Yamorichan, began serialization on Overlap’s Comic Gardo service in June 2020. The manga has been compiled into multiple volumes and is published in English by Seven Seas Entertainment. An anime adaptation of the series, produced by the animation studios Felix Film and GA-CREW, is scheduled to premiere in October 2024. The story follows Noel, who aspires to become a great seeker like his legendary grandfather but is assigned the supposedly weakest support class, Talker, leading him to use cunning strategy and manipulation to achieve his goals.

Information regarding Jaki’s personal background, artistic identity, or recurring thematic preoccupations across other works remains unavailable, as the creator is primarily known for this single series. The consistent use of the name Jaki across all official publications for the light novel, manga, and anime credits confirms this authorship. The industry significance of Jaki’s work is evidenced by its transition from a web novel to a commercially published light novel, its subsequent adaptation into a long-running manga series, and its forthcoming anime adaptation, indicating a successful trajectory within the contemporary Japanese publishing and media mix landscape.
