It would be easier to ask who is straight in JTA, that is a much, much, shorter list.
Everyone from heroes to villains (and even some being who you could call gods) have some sort of an LGBT identity to them. I wanted to create a very positive world in that aspect,
Just out of the main cast of season 1.
Vernon is Demisexual, and pretty against defining gender, but will go by he.
Azreth is Pansexual, and mostly masculine (and that won't always be the case)
Grey is Bi, and pretty decidedly masculine,
Drake is not very well resolved on that front, so we don't know... Yet.
Lisa is Bi, and cares not to define her gender,
Yggreth is Pansexual, and androginous.
Azerius is Graysexual, and entirely masculine, which is rare for a dragon in JTA as they are mostly genderfluid.
Hemlock is a demon, and they lack an actual sexual impulse or gender identity,
A lot of these won't be factored into the plot itself (maybe a side chapter), but I like to think about that sort of stuff. ^^
