Nishikata receives his first cell phone and can't wait to play tricks on Takagi-san.
He sends her a scary video to frighten her, but it doesn稚 quite work. 
As usual, Takagi-san has the upper hand when it comes to teasing...
I-I'll be fine!
!سـ-سأكون بخير
I-Ich pack das!
¡Estaré bien!
¡Estaré bien!
Pas de souci, ça va aller.
Essayez, pour voir.
I-Invece rimarrò!
E-Eu aguento!
Не испугаюсь!
Давайте, проверьте меня!
