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...
He was letting students 
keep their smartphones,
كان يترك التلامذة يحتفظون بهواتفهم الذكية
Da hat man schon einen Lehrer,
dem sonst Handys im Unterricht egal sind …
Dejaba que todos usaran sus celulares
Il laisse toujours couler,
quand un élève a son portable.
Ele sempre deixa os alunos 
ficarem com o celular,
Он закрыл глаза на то,
что ученики носят телефоны,
