In Amaranto, is Troy a girl or boy?

Question

In the Visual Novel Amaranto, one of the members of Triad is Troy. I'm playing the English patch of it now, and they refer to Troy as a "she". When they say Troy's name, it does sound exactly like they've translated it. However I'm confused about whether this is a translation error or not.

Points that indicate that Troy could be a girl

• All characters that are in the story or mentioned but two are girls (the two guys being a nameless vagrant that Mio was about to kill and the strawberry-loving owner of the cafe Yuuki's group hangs out in).

• It's noted that Queen hates men, even going so far as to kill most of them off when she takes over a Sect, and since the Triad are like her elite guard, she would have nothing but girls in it.

• The twins joke about how Troy only has eyes for "Senpai" which refers to Ria, since all the relationships shown/possible are Shoujo Ai (female × female). So, this would be the same with Troy and Ria.

Points that indicate that Troy could be a boy

• Troy is a guy's name at least in English (in Japanese, it's pronounced as to-ro-i / トロイ) however in the game it seemed to be pronounced as to-ro-i-a / トロイア so the English name may be a mistranslation.

• Troy's appearance:

• Troy sounds like a boy (but that could mean little)

So I am wondering, is Troy a girl, or is Troy actually a boy (and the translation is wrong)?

Answer 1

This is Troy's profile from the official site's character introduction.

Although Troy's appearance is like a boy, Troy is a she. From the last paragraph of Troy's description:

口数が少なく、常に行動を共にする双子も
彼女のことはよく知らない。

Does not talk much, and even the twins whom Troy usually act together with
do not know much about her.

While VNDB claims that she is also a transgender, I don't have any proof to support or counter it. However, from the sample dialog on the image,

「そんなの、ボクには関係ない。
　　君たちの好きにすればいいだろ」

she refers to herself as ボク (boku) which defines her personality as a bokukko (Warning: TV Tropes link)

A Bokukko is, literally, a girl who uses the first-person Japanese Pronoun boku, primarily used by boys and young men. [...]

Most bokukko are tomboys, but not all; sometimes it just indicates that the user is a Plucky Girl or unaware of social norms. [...] Although none of this has to be reflected in her appearance, bokukko are usually either flat-chested or extremely well-endowed.

This speech pattern can also be used to keep a character's gender obscured—is she a boyish girl, or a girlish boy?

Last but not least, Kisaki Kotori ― the voice-actor herself ― listed her role on her official site as female for Troy.

Regarding the name トロイア (toroia) as Troy, most possibly it refers to Troy, a city used as the setting of the famous Trojan War. Japanese Wikipedia lists トロイア (toroia), トロイ (toroi) and トロイアー (toroia-) as the possible pronunciations.
