Synopsis
Oushitsu Kyoushi Heine follows Heine Wittgenstein, a small but brilliant man, as he's appointed the royal tutor to the four princes of Grannzreich.
Each prince – Licht, Leonhard, Bruno, and Kai – possesses unique and challenging personalities that Heine must overcome to prepare them for potential kingship.
The story focuses on Heine's efforts to connect with and educate the princes, leading to comedic situations and character development as he navigates their individual quirks.
However, the series also hints at a deeper mystery surrounding Heine's past and potential threats to the kingdom's stability, adding a layer of intrigue to the lighthearted premise.
