Ash (Or Jackson-sensei to his students) is an American man teaching at a Japanese high school on a visa.  He’s very handsome and somewhat fluent in the Japanese language, though sometimes he’ll make mistakes here and there.  He tries to be as nice as he can to every student.  However since he’s from America, he is very unfamiliar with Japanese culture and tradition.  He’s trying his best though.  His handwriting sucks though.  He’s bisexual.
