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...

إي... إيشي-سان؟
Ku… Kushii-san?
I… ¿Ishii-san?
I… ¿Ishii-san?
I... Ishii?
I... Ishii-san?
