Now that the choir has ten members, it's time to get serious about entering the Kanto boys choir competition! The boys find out that last year's national winners are performing at a festival, so they go to check them out. Then they run into Maiden's dad!
That jerk is running off and leaving 
Rika-sensei behind! He's unbelievable!
!ذاك الوغد يرحل تاركاً ريكا-سينسي! لا يُعقل
Quelle enflure !
Il laisse Mme Rika et s’enfuit tout seul.
Scappa via lasciando qui la professoressa Rika.
Davvero inconcepibile.
Maldito...
Этот гад взял да и бросил вас
 в одиночестве! Как так можно?
