Royal tutor Heine has been tasked with grooming four princes into potential kings. He’s interviewed the proud Prince Leonhard, but three more princes await: the highly intelligent Bruno, freewheeling Licht, and perpetually-glaring Kai. With each prince's personality as unique as the last, interviewing them will prove to be anything but straightforward...
Now, to collect myself. 
Only Prince Kai remains.
.والآن، لأراجع نفسي. بقي لي الأمير كاي فقط
Ruhig Blut.
Nur noch Prinz Kai verbleibt.
Bien, repasemos.
Solo falta el príncipe Kai.
Bien, repasemos.
Solo falta el príncipe Kai.
Bon, j’ai repris mes esprits.
Plus que le prince Kai.
Molto bene, ricomponiamoci.
Enfim, para concluir,
resta a Sua Alteza Kai.
Остался только принц Кай.
