Renji Kuriyama is a Japanese manga artist whose professional work is primarily associated with illustrating manga adaptations of existing stories. Kuriyama is best known for his contributions to the King's Game franchise, a series of manga that began as a cell phone novel written by Nobuaki Kanazawa. Kuriyama did not create the original story for King's Game but served as the artist for multiple manga sequels and spin-offs within the franchise. The original manga series was drawn by a different artist, Hitori Renda.

Kuriyama's role as an illustrator is clearly defined in the credits for the King's Game series. He is listed as the artist for the manga King's Game Extreme, which was published by Futabasha in five volumes between November 2012 and July 2014. He also drew King's Game Spiral, a four-volume series published between January 2015 and November 2016. It was the manga adaptation by Kuriyama that served as the basis for the anime television series King's Game The Animation, which aired in October 2017.

Beyond the King's Game franchise, Kuriyama has worked on other manga series. He is the artist for Call to Adventure Defeating Dungeons with a Skill Board, a fantasy action manga based on web novels. The series is published by Seven Seas Entertainment, and Kuriyama collaborates with author Aki Hagiu, who writes the story. The first volume was released in August 2021, and multiple volumes have followed.

Kuriyama's early work includes contributions to anthology comics, such as the four-panel anthology Starry Sky in Summer, released in April 2010. His career demonstrates a focus on adapting prose narratives into visual manga form, particularly within the horror, suspense, and action genres. While his name is associated with a popular anime title, his credited role is consistently that of a manga artist and illustrator, not the originator of the story concepts.
