Nice to meet you, my name is Yanase Mei.
As soon as I started high school, not only did I end up in a class with a very odd teacher, surrounded by odd classmates, but I was forced to be class representative in a day full of upheaval.
Iwasawa-san "Saki-chan" 
instead of by a nickname.
le pusiste un apodo a Iwasawa-san, y la 
llamas "Saki-chan" en lugar de eso.
no tiene uno de tus apodos, 
sino que la llamas "Saki-chan".
deu um apelido pra a Iwasawa-san, 
mas chama ela de Saki-chan.
