As a reward for saving the kidnapped Princess Flora, Rio has been enrolled in the primary school branch of the Beltrum Royal Academy. However, the students at the academy are mostly the children of royalty and the nobility, and they do not welcome the orphaned Rio. With so many scornful gazes turned toward him, there is one person who worries for him—Celia, a girl of twelve who is nonetheless, at her young age, the lecturer in charge of the primary school. As Rio cannot read, Professor Celia begins privately tutoring him after school.
I said I don't mind! You're so mean, Rio!
!قلت أنني لا أمانع! أنت لئيم حقا يا ريو
Ich habe doch gesagt, dass es mir
nicht unangenehm ist. Du bist so fies!
¡Dije que no me molesta!
¡Qué malo eres, Rio!
Je te dis que non !
Ce que tu peux être méchant !
Ho detto che non c'è problema!
Uffa, Rio, sei tremendo!
Eu disse que não acho ruim!
Você é maldoso, Rio!
Сказала же, я не против! 
Рио, ну ты и злюка!
