Not knowing who this is, but rather based on what I see, which is: anus, no clear vagina, and possibly (probably) testicles, I'll assume it is, in fact, a dude.
Anonymous said: To be exact, this isn't Mashiro. It's "Manshiro" (his real name is never revealed.) He's the guy who poses as Mashiro after she's "assassinated."
yeah on the first f*ing page apparently they're twins as well so hes technically the prince/king anyway
