The Greatest Magicmaster's Retirement Plan is a Japanese light novel series written by Izushiro and illustrated by Ruria Miyuki.

J-Novel Club licensed the light novel series for English releases in March 2019. A manga adaptation by Yū Uonuma began serialization online in Hobby Japan's Comic Fire manga website from July 2017 to January 2019 before it got canceled.

Plot
100 years ago, out of nowhere, humanity faced a new enemy and was gradually driven out of its land. This enemy was an abomination called "Fiends", and they wielded devastating power in which conventional weaponry was useless. 100 years later, humanity is yet to reclaim their lost lands, and remnants of human civilizations are splintered into seven countries but are united against the fiends. A massive magical barrier was erected by Babel in the center of the seven nations, thwarting the fiends' invasion and saving humanity from extinction.Magicmasters, numbering in the hundreds of thousands, are what stand between humanity and its extinction, protecting their countries against the Fiends. Magicmasters distinguish themselves through a numerical ranking system. The lower their digits, the stronger the Magicmaster is. Alus Reigin, protagonist and Magicmaster from the nation of Alpha, has been battling the fiends since the age of six. He has reclaimed more of humanity's lost territory than anyone else alive. One day at the age of 16, he requests retirement from military services. Naturally, the governor-general can not accept his resignation, and so they reach a compromise. With that, he ends up as a student at Second Magical Institute, forced to hide his identity, but some of the select few knew who this boy truly is.
He finds himself a partner, Loki Leevahl, to aid in his mission. He also ends up training his successors, Tesfia Fable and Alice Tilake. He even comes across the daughter of his former superior, Felinella Socalent. On top of his growing list of responsibilities and frequent messes in dealing with these beauties, he resumes his research and continues to defeat the Fiends in secret.
