The May 2021 issue of Square Enix’s Monthly G Fantasy magazine has announced that Higasa Akai’s The Royal Tutor (Ōshitsu Kyōshi Heine) 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 manga in Monthly G Fantasy in November 2013. Yen Press began releasing the manga as e-books in English in 2015.
