Princes Kai, Bruno, Leonhard, and Licht have been making great strides thanks to an excellent education from Heine, the royal tutor. Even so, with the return of Prince Eins, the eldest of the brothers and heir apparent to the crown, the wall they must climb in the struggle to become the most qualified candidate for the throne looks more colossal than ever. Can the four younger princes stand up to their biggest rival?... Kai makes a friend at school and invites him over to the palace for tea. He asks his brothers for help in making conversation, but is that really such a good idea...? Then it's a battle of wits when Heine joins the princes (and princess!) for a game in the courtyard. After all the time they've now spent under his tutelage, can the students finally overcome the master?
