On school festival day, the gang sells a ton of rice balls thanks to an innovative Prince Yuki marketing technique. Bonus: two other members of the Soma family come to the festival to introduce themselves.
I'll head back to the classroom.
Ich gehe schon mal zurück.
Volveré al salón.
Bon, je pars devant.
Vou voltar para a sala de aula.
Ну, пойду в класс.
