What is The Greatest Magicmaster's Retirement Plan about?

The fantasy anime is based on a novel series written by Izushiro and illustrated by Ruria Miyuki. It began serialising in the Shōsetsuka ni Narō website in 2014. Later, Hobby Japan started publishing the story in print format with illustrations by Miyuki in 2017. A manga adaptation by Yu Uonuma began on the Comic Fire manga website in the same year. A second manga adaptation by Karu Yoneshiro titled The Greatest Magicmaster's Retirement Plan: The Alternative began serialising in Square Enix’s Manga UP! website in 2020 and ended in 2023. 

J-Novel Club publishes the light novels in English and describes the story as:

In a world where the Fiends run rampant... Magicmaster Alus Reigin, the young prodigy that has defeated more Fiends and reclaimed more of humanity’s lost territory than anyone else alive, requests retirement from military service at age 16. But due to the twists and turns of fate surrounding his status as the No. 1 Magicmaster in the nation—the top Magicmaster out of more than 100,000—he ends up as a student at a special magical institute, hiding his identity and training his successors – a pair of beautiful Magicmaster girls! Not to mention continuing to defeat Fiends in secret... Get ready—the epic adventure of the Greatest Magicmaster Alus Reigin begins now!

To celebrate the anime adaptation of the original novel, a prequel manga series titled The Greatest Magicmaster's Retirement Plan Zero -The Secret History of the Beginning- (Saikyō Mahōshi no Inton Keikaku Zero -Hajimari no Hishi-roku-) illustrated by Yoneshiro will launch this winter. It will follow Alus’ life in the academy and connect to the main story eventually.
