Wasn't trying to be. As for your assertion 1) I'm not one of those "many people" since if everyone did everything the same way, the world would be an incredibly boring place and 2) if it worked for his original design and the real-life singer on which Gakupo is based, then I'd like to think it could work here.
That is one of the least accurate depictions of him. And, yes, it's a him. If you listen to his (synthetic) voice, Gakupo is clearly male. I don't intend to fan-rant, but it bothers me when mix-ups like this occur. (I don't know how to put links in, but here are some urls to some info on him.) [link] [link] [link]
