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!
So you're the one who 
tricked my son, are you?
أنت من خدع ابني إذاً؟
Du bist also der Hauptgrund,
dass mein Sohn vom Weg abkam …!
Alors c’est vous qui avez volé
la vocation de mon fils ?
Allora sei stato tu a raggirare mio figlio, dico bene?
Foi você quem persuadiu
o meu filho, não foi?
Так это ты моего сына обманул?
