This year's 10th issue of Kodansha's Weekly Shonen Magazine is announcing on Wednesday that Ken Akamatsu will end his Negima! Magister Negi Magi manga after three more chapters. However, he will first take a two-issue hiatus to prepare for the end, so the series will return in this year's 13th issue of the magazine on February 29. The finale will not come until this year's 15th issue in March, at the earliest.

Akamatsu launched the manga in Weekly Shonen Magazine in 2003, and Kodansha is publishing the 37th compiled book volume this month. Del Rey Manga began publishing the manga in North America, but Kodansha USA took over publishing duties for this title and others in 2010. The manga inspired a television anime series, several video anime releases, a live-action series, a film, and a few manga spinoffs.
