The May 2021 issue of Square Enix’s Monthly G Fantasy magazine has announced that Higasa Akai’s The Royal Tutor manga will end in the magazine’s next issue on May 18, 2021.

The story of the manga is described as:

Accepting the post of Royal Tutor at the court of the king of Grannzreich, Heine Wittgenstein is a little professor with a big job ahead. Each of the kingdom’s four princes has a rather distinct personality. Does their diminutive new instructor have what it takes to lay down some learning? It’s a comedy of educational proportions.

Akai launched The Royal Tutor in Monthly G Fantasy in November 2013. Yen Press began releasing the manga as e-books in English in 2015.
