This year's combined 36th and 37th issue of Shogakukan's Weekly Shonen Sunday magazine revealed on Wednesday that Yellow Tanabe will launch a new manga titled Kaihen no Mahōtsukai (Wizard of Changing Borders) in the magazine's 42nd issue on September 11. The "oriental fantasy" manga centers on a hermetic and eccentric magician in the frontier encountering a mysterious boy.
Tanabe began serializing the Kekkaishi manga in Weekly Shonen Sunday in 2003 and ended it after eight years in 2011. The manga inspired a television anime adaptation that ran from 2006 to 2008. Viz Media released the anime in a set of four DVDs in 2011, and Discotek Media later released the anime on Blu-ray Disc in June 2022.
