Interview with a Prince II is the third chapter of the Oushitsu Kyoushi Heine manga.
After assessing Leonhard, Heine meets with the third prince, Bruno. Bruno is widely known as a genius and despite being only sixteen, he had already published numerous theses. Bruno is less resistant than Leonhard, but looks down on Heine because of his lack of a formal education and challenges him to several tests in order to prove that he's worthy to be his tutor. Heine aces all of the tests, causing the extremely competitive and perfectionist Bruno to despair. However, when Heine begins to perfectly analyze and understand one of his theses, he's overcome with respect and the realization that he met someone who can give him useful guidance, and begins to call him "master". Heine is weirded out by this, but wonders if the reason why Bruno wanted to test him is because he was searching for a worthy teacher. As Heine tries to dissuade him from calling him "master", the youngest prince, Licht, barges in and carries Heine away.
