I’m sure a lot of Kuroshitsuji (Black Butler) fans wonder what gender Grell Sutcliff is. In my opinion, Grell is a male.
But, several episodes he referres to himself as a woman. For example, in season one, episode eleven, he says:
“You think I’m the type of woman you can just buy with money?”
Of course, I’m not saying that your opinion is wrong, if you think he’s male, like I do, but, Yana Toboso refers to him with female pronouns most of the time.
With all that said, Grell Sutcliff’s gender still remains up to you Kuroshitsuji fans.
