So the game is intentionally left vague so that neither character is directly gendered (and they both have gender neutral names), and there’s actually some flavour text where an NPC asks your gender and Kit refuses to answer! I wanted anyone to be able to project on them, whether they see them as T4T, both nonbinary, lesbians, gay dudes, whatever! I suppose canonically that would make them both Agender though (hey, just like me!). I hope it’s not a problem that it isn’t super explicit.
That said? My personal headcanon for them is that they’re both transmasc. :3
