Muneyuki Kaneshiro is a Japanese manga writer born in 1987 and a native of Osaka Prefecture. He is a graduate of Kyoto Seika University, where he completed the university’s Manga Production course. Before his professional debut, he received the Special Encouragement Award at the 80th Weekly Shōnen Magazine Newcomer Manga Awards for an early work.

Kaneshiro made his professional debut as a writer in 2011 with the series As the Gods Will, illustrated by Akeji Fujimura. The series, which ran until 2012, was followed by a sequel, As the Gods Will: The Second Series, serialized from 2013 to 2016. The original manga was adapted into a live-action film in 2014. Throughout the 2010s, he continued to write stories for several manga across different genres, including Billion Dogs, Bokutachi ga Yarimashita—which was adapted into a live-action television series—Jagaaan, and Grashros, collaborating with various artists.

His most prominent work is the sports manga Blue Lock, which he launched with illustrator Yusuke Nomura in Weekly Shōnen Magazine in August 2018. The series became a commercial and critical success, winning the 45th Kodansha Manga Award in the shōnen category in 2021. Blue Lock was adapted into an anime television series that premiered in October 2022. Kaneshiro is also credited as the original creator for the spin-off manga Blue Lock: Episode Nagi, illustrated by Kōta Sannomiya, which was adapted into an anime film released in April 2024.

A recurring element in Kaneshiro’s narratives is a focus on psychological intensity and individual ambition over traditional notions of teamwork and selflessness. In developing Blue Lock, he has stated that he finds it difficult to write characters who live selflessly for others and instead builds stories around the concept of a positive, ego-driven individualism. This theme is evident across his body of work, which often places characters in high-stakes survival scenarios or competitive environments that challenge societal norms.
