From Yen Press: 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!
