The green haired girl was interviewed in the third page, she said she was going to be a cow from now on when they asked her if she had a job already. She also said she was twenty. After thirty days, she forgot her actual name, because the attendant gave her a new one, Sayoko. When asked about her job and age, she said that she was a one year old cow. So long story short, she was modified I guess?
It's good to see in english for understand , because it's a bad joke to translate it in Korean and no in english. (and many Manga or cg is only translated in oriental language but not in english ... it's realy a bad joke , ok translate it in korean or Chinese but make a english translation in a month after .)
