A student is caught cheating with his cell-phone, and Chiaki is super-mad! He calls all the students to an assembly and angrily threatens to destroy the phone of anybody who's caught with one on school grounds.  The students begin to get angry...
I apologize for betraying the teachers' trust
أعتذر على خيانة ثقتك بأسوأ شكل ممكن
Wir haben das Vertrauen der Lehrkräfte uns
gegenüber in schlimmster Weise ausgenutzt.
me disculpo por traicionar la confianza
de un profesor de la peor manera.
je vous prie d’accepter
les excuses de tous les élèves
vorrei scusarmi a nome di tutti
per aver tradito nel modo più abietto
eu lhe peço desculpas por 
traírem a sua confiança
я прошу прощения от имени учеников
за то, что мы предали ваше доверие
