Film with returning cast, director introduces 2 original "Twin Princes" characters Ivan, Eugene

The staff of the The Royal Tutor anime revealed on Tuesday that the franchise will get an anime film with an original story. The film will open in Japan on February 16, 2019.

The story will have two new characters, the sadistic "Twin Princes" of the Ramano kingdom: Ivan (left in below visual) and Eugene (right) Aleksandrovich. (Note: Name romanizations are not official.)

Keisuke Ueda, Yūya Asato, Yūto Adachi, Daisuke Hirose, and Shouta Aoi all return from the anime to reprise their roles as Heine, Kai, Bruno, Leonhard, and Licht, respectively.

Katsuya Kikuchi returns to direct the film, and Kimiko Ueno is returning for the script. Rena Okuyama is still credited with the animation character design, and is also taking on the role of chief animation director. Hozumi Gōda and Keiji Inai are returning as sound director and music composer, respectively.

A special LINE LIVE streaming program revealed in June that the anime would have an announcement on September 18.

The anime adapting Higasa Akai's manga premiered in Japan in April 2017, and Crunchyroll is streaming the series with English subtitles.

Yen Press began releasing Akai's original manga as e-books in English in 2015, and it describes the story:

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 manga in Monthly G Fantasy in November 2013, and Square Enix published the 11th compiled book volume on July 27.
