~ Um....abt Hiromu Arakawa Sensei... ~
i really want to know whether Arakawa sensei is a male or female...i know his name was a male name (and i believed that he's a male)...but there are some people saying that they saw in the GANGAN magazine said that he is a female...so...i don't really know whether he is a male or a female...?
